Abstract :
A 1 times 8 monopulse microstrip patch antenna array in Ka-band has been proposed. The radiating element is a modified circular patch antenna, designed for getting circular polarization. The feed network is composed of six Wilkinson power dividers, a 3 dB hybrid, and a microstrip to waveguide transition. Both the array and the feed network are placed on the same layer.
