Abstract :
A fixed beam (broadside) two-dimensional microstrip array of 16×16 resonant rectangular radiating elements at the frequency of 8.15 GHz with a gain of 29.5 dB is presented. A modular approach is utilized in which a given antenna is used as a building block for a higher-gain antenna. The high efficiency is achieved by optimising the layout and the impedance levels of subarray feeding of the conventional uniformly illuminated monolithic array.
