In aperture coupling, ground plane is used to minimize the inference due to spurious radiation.(a) True(b) FalseI have been asked this question by my college director while I was bunking the class.This intriguing question comes from Feed Methods in section Slot & Microstrip Antenna of Antennas

Answer»

Right answer is (a) True

Best explanation: In Aperture coupling, TWO different substrates are separated by ground plane.This type of arrangement optimizes feed mechanism and RADIATING element. The ground plane is between the substrates and isolates feed from the radiating element and minimizes the interference DUE to SPURIOUS RADIATION.
