X- Band Microstrip Antenna for Radar and Amateur Radio Service

Abstract

Microstrip antennas and arrays are used as an alternative for the bulky and heavy weight reflector/slotted waveguide array antennas. For radars which demand a low profile, light weight antenna subsystem, the microstrip antennas are an ideal choice. The proposed antenna is designed in the X-band for the radar and missile application. It is a dual band antenna with resonant frequency of 8.5 GHz and 10.132 GHz having return loss 38.59 dB and 45.98 dB.
