Abstract

A two-dimensional (2D) monopulse microstrip array antenna for X-band missile terminal guidance radar application is proposed. The design consists of microstrip array radiation front-end and four quadrants microstrip hybrid couplers back-end. The microstrip array comprises four rectangular patches etched on the top side of upper substrate layer. Four corresponding 3dB directional couplers are connected to form a four quadrant monopulse comparator and etched on the bottom side of lower substrate layer. Both layers are made of Rogers 5880 substrate and punched with four metal probes to prove the feeding from back-end to front-end. The whole structure can be fabricated with standard multilayer printed circuit board (PCB) or 3D printing process. Optimization results show about 11.5dBi max gain of sum pattern and -28dB null-depth of difference pattern in E and H planes at 10GHz center frequency.
