Abstract :
It is proposed that the radar cross section (RCS) of a microstrip antenna can be effectively reduced over a broad frequency band by utilizing a well-designed meshed ground plane. The radiation characteristic of the microstrip antenna is only slightly influenced by cutting slots on the ground plane. The calculated results suggest that the meshed microstrip ground antenna has much lower RCS than the solid ground one over a band 1-18GHz, with a maximum reduction of 15dB, while the radiation performance of the microstrip antenna, such as gain, impedance bandwidth and so on, remains almost the same as that of the solid antenna.
