Antenna Theory PS#02 | 4-Element Broadside Array

Instructor: Dr. Süleyman Burak ÇELİK

In this problem-solving session we analyze a 4-element uniform linear array configured for broadside radiation. With element spacing d = lambda/2 and zero progressive phase shift, we compute the array factor, locate the null angles, determine the half-power beamwidth, and sketch the polar radiation pattern.
