InterviewSolution

1.	Two identical antennas are placed in the θ = /2 plane as shown in the figure. The elements have equal amplitude excitation with 180° polarity difference, operating of the far-zone resultant electric field strength normalized with that of a single element, both computed for φ = 0, is
Answer» Normalised array factor = n cos where φ is the phase difference. φ = (βd sin θ cos φ + θ1) and θ = 90°, φ = 45°
