Antenna solved problems pdf One of those we commonly run into is the application of ISM band radio equipment in unique situations. In this text, noted author Professor Syed Nasar has divided the book's problems into topic areas similar to a textbook and presented a wide array of problems, followed immediately by their solutions. Luckily, there is a uniform process that we can use to solve these problems. It seems to be serious science, but the results are most definitely not in Lumia's favor. Just found a very odd recently made study of mobile phones antenna performance. Then draw a vertical line up from this point and determine the value of f at this point. Solution: Given data: solution of the antenna placement problem. Antenna problems: 1. Finite-length dipoles. This power variation as a function of the arrival angle is observed in the far field. The lament behaves approximately as a black body, emitting radiation isotropically. Now I am making a rhombic model using cylindrical wires, but I am not sure how to get HFSS to recognize the model as 3 dimensional. All full-power television stations have stopped broadcasting in analog, and now broadcast only in digital. Antenna with a 20 degree beamwidth has a 20 dB gain.

These are arrays that can be sorted. The array b[] is a duplicate of a[]. Similarly, the array d[] is a duplicate of the array c[], each containing three String elements.

In both cases, the duplication is obtained by invoking the clone method. Since it returns a reference to an Object, it must be cast to the array type being duplicated, int[] or String[]. The last part of the example shows that the cloned array d[] is indeed a separate copy of c[]: Changing c[1] to "XYZ" has no effect upon the value "CD" of d[1].

The name of this class is Arrays, and it is defined in the java. Arrays Class This program imports the Arrays class from the java. It also imports the static print method from Example 2. At line 7, the call Arrays. At line 9, the Arrays. The second argument, 44, is the search target.

The method returns the index 2, which is assigned to k at line 9. Line 11 verifies that 44 is indeed the value of a[2]. The method is invoked again at line 13, this time searching for the target The output from line 17 shows how the Arrays. It will return true only if the two arrays have the same element type as a[] and b[] do: int[] , the same length as a[] and b[] do: 8 , and the same values at each element a[] and b[] do not.

The java. Arrays class is outlined in more detail in page It is also the least efficient. It simply examines each element sequentially, starting with the first element, until it finds the key element or it reaches the end of the array.

If you were looking for someone on a moving passenger train, you would use a sequential search. Return 1. It is implemented in Example 2.

The method returns —1 when the target is not in the array: search a, 50 returns —1, because 50 is not in the array. The sequential search is correct. This means that it works.

The following argument is a proof of that fact. Only step 4 executes, immediately returning 1. If s0 z x, then the loop terminates, step 4 executes, and 1 is returned, and that satisfies the postcondition because the single element of the sequence is not equal to x. We want to apply the First Principle of Mathematical Induction to deduce that the loop invariant must be true on every iteration of the loop.

See page That requires the verification of the invariant on the first iteration and the deduction of the invariant on iteration i from the corresponding invariant on iteration i 1. If s0 z x, then the loop continues on to a second iteration. Thus, si z x. This means that, on average, the running time is proportional to the number of elements in the array.

So if everything else is the same, then applying the sequential search to an array twice as long will take about twice as long, on average. If x is not in the sequence, then the loop will iterate n times, making the running time proportional to n, which is O n.

It is much more efficient than the sequential search, but it does require that the elements be in order. It repeatedly divides the sequence in two, each time restricting the search to the half that would contain the element. You might use the binary search to look up a word in a dictionary. Let ss be a subsequence of the sequence s, initially set equal to s. If the subsequence ss is empty, return 1. Invariant: If x is in the sequence s, then it must be in the subsequence ss.

Let si be the middle element of ss. Repeat steps 2 7 on the subsequence of ss that lies below si.

The binary search is correct. The loop invariant is true on the first iteration because the current subsequence is the same as the original sequence. On every other iteration, the current subsequence was defined in the preceding iteration to be the half of the previous subsequence that remained after omitting the half that did not contain x.

So if x was in the original sequence, then it must be in the current subsequence. Thus the loop invariant is true on every iteration. Since the original sequence has only a finite number of elements, the loop cannot continue indefinitely. Consequently, the algorithm terminates either by returning i from within the loop or at step 6 or step 7 where 1 is returned.

In that case we know by the loop invariant that si is not in the original sequence.

This means that, on average, the running time is proportional to the logarithm of the number of elements in the array. So if everything else is the same, if it takes an average of T milliseconds to run on an array of n elements, then will take an average of 2T milliseconds to run on an array of n 2 elements. For example, if it takes 3 ms to search 10, elements, then it should take about 6 ms to search ,, elements! Each iteration of the loop searches a subarray that is less than half as long as the subarray on the previous iteration.

Thus the total number of iterations is no more than the number of times that the length n can be divided by 2. That number is lgn. And the total running time is roughly proportional to the number of iterations that the loop makes. Review Questions 2. Problems 2. The interpolation search can be shown to run in O lglgn time. If it took 5 ms to run on an array of 1, elements, how long would you expect it to take to run on an array of 1,, elements on the same computer? Use the following algorithm to compute and print a sieve of size Precondition: p is an array of n bits.

Postcondition: p[i] is true if and only if i is prime. Initialize p[0] and p[1] to be false, and all other p[i] to be true. Repeat step 3 for each i from 3 to n, incrementing by 2. If there is a prime d the square root of i that divides i, set p[i] false. Vector object. BitSet object. One other fact, such as the sum or product of the numbers, is also given.

What can be the problem? If you need more info or you misunderstood something feel free to ask. Vector Magnetic Potential Page 1 Vector Magnetic Potential In radiation problems, the goal is to determine the radiated elds electric and magnetic from an antennas, knowing what currents are owing on the antenna.

Answer: One definition: Antenna is a device which moves electromagnetic energy from two dimensional space to three dimensional space and vice versa.

If you notice that your reception isn't as good as it used to be, or you're noticing other problems with your TV antenna, there are a few ways to recognize the problem so you can fix it.

Here we exchange ideas on the Cadence meaning of this error? I replaced the antenna, checked the wiring in the antenna violation with calibre DRC.

Answers are given for most of the problems. These are acknowledged by inserting the citation. Method of images — revision. No need to build it or download it from aur anymore. Most antennas are resonant devices, which operate efficiently over a relatively narrow frequency band.

In the diagram below is shown an antenna array with its elements along the z axis such that the distance between each two successive elements is Chapter 1 Solved Problems Problem Problem Problem Problem Problem Problem Problem Problem Problem Problem Fawwaz T. Antenna arrays are formed by assembling identical in most cases radiating elements such as dipoles for example.

We Antennas come in two styles, band specific, and combo. Focus of this course more mature and developed Synthesis problem Given the desired operational characteristics like the radiation i am pretty new at the base station side of radios,so when i decided to put up a base antenna i thought "no big deal anybody can do it" guess i lied to myself.

Find the maximum power delivered to a matched load at the receiver when W of power is supplied to the transmitter. Anyone have any info on the rumors concerning antenna problems with the Razr Maxx HD?

I read that the antenna is on the bottom of the phone and may actually be touching the frame. The electric field linesat a certain instant in time are shown. An antenna is a device for converting electromagnetic radiation in space into electrical currents in conductors or vice-versa, depending on whether it is being used for receiving or for transmitting, respectively.

The antenna is attractive due to its low-profile conformal design, relatively low cost, and very narrow bandwidth. Chapter 4 Solution to Problems Question 1. The signal is then routed to a Problem 9. The signal is then routed to a of Eq. The results obtain that microstrip patch antenna can be used as client antenna in computer and workable antenna for wireless fidelity. The monopole and its variations are common in portable equipment, such as cellular telephones, cordless telephones, automobiles, trains, etc.
