摘要
Abstract
For wideband radar cross section (RCS) reduction of circular polarized (CP) microstrip antennas,a novel metasurface with the partially reflecting characteristics and the polarization conversion characteristics is proposed to enhance the gain and broaden the RCS reduction bandwidth of CP microstrip antennas simultaneously.The simulated results indicate that the gain of the proposed antenna is enhanced about 1.4 dB around the operating frequency compared with the reference microstrip antenna.The proposed antenna has a lower RCS value than the reference antenna in the frequency range from 9.7 GHz to 21 GHz,in which the average RCS reduction is 9.06 dB for xpolarized incident wave and 9.21 dB for ypolarized incident way erespectively.The simulated results demonstrate the validity of the design and show that the proposed method helps to realize the wideband RCS reduction of CP microstrip antennas and is useful for the stealth technology of CP microstrip antennas.关键词
