WebQuestion: 1. For a non-uniform broadside linear array derive the expression for array factor if the array has (i) even number of elements and (ii) odd number of elements. 2. Draw and explain the radiation pattern of monopole antenna in … WebPlanar arrays are more versatile; they provide more symmetrical patterns with lower side lobes, much higher directivity (narrow main beam). They can be used to scan the main beam toward any point in space. Applications – tracking radars, remote sensing, communications, etc. 1.1 The array factor of a rectangular planar array Fig. 6.23(b), pp ...

WebThe factor multiplying jE 0jabove is also called the array factor. The above can be used to plot the far- eld pattern of an antenna array. Equation (27.1.7) has an array factor that is of the form jsinNxj jsinxj This function appears in digital signal processing frequently, and is known as the digital sinc function [133]. WebThe Array Factor is a function of the positions of the antennas in the array and the weights used. By tayloring these parameters the antenna array's performance may be optimized to achieve desirable properties. For instance, the antenna array can be steered (change … The resulting Array Factor for this array becomes: In the above, k is the wave … how much is parents benefit
