一种新型高增益低雷达散射截面微带天线
Novel high gain and low RCS microstrip antenna
摘要
Abstract
A double screen frequency selective surface(FSS) is designed and applied as the radome of the microstrip antenna.By analyzing the transmission line model and simulating the electric field distribution and current distribution on the double screen frequency selective surface at the resonance frequency,its physical mechanism of wave-transparent is theoretically investigated.The new antenna high-gain and in-band radar cross section(RCS) reduction mechanism is analyzed by the ray theory and phase cancellation principle.Simulation and measurement results demonstrate that:the application of the double screen FSS has hardly influence the bandwidth of the antenna,while the gain of antenna is enhanced by 5.49 dB,the half-power beam width of the E-plane and H-plane is reduced 63°and 52°,respectively.The RCS of the antenna is reduced by 5 dB or more in an operation band from 2~18 GHz,and the in-band RCS reduction of the antenna is above 5 dB from -23°~23° and the maximum reduction value exceeds 20.94 dB in the boresight direction.关键词
