【摘要】 传统的Fabry-Perot谐振腔天线通常在部分反射层里面使用了介质基板,本文设计了一款新型的FP谐振腔天线,其采用了全金属的双层缝隙结构作为部分反射层,在一定频率范围实现了实现了正向变化梯度的反射相位。仿真结果表明该FP谐振腔天线在10.52 GHz-10.898 GHz频率范围之间满足|S₁₁|<-10 dB,在10.7 GHz时增益为17.65 dBi,相应的口径效率为42.88%;与不加覆盖层相比,增益的提高量为7.145 dB。更多还原

【Abstract】 Traditional Fabry-Perot antennas（FPAs） usually use dielectric substrate in the partially reflective layer.This paper designs a new type of FPA,which uses a double-layer all-metal slot structure as partially reflective layer and positive phase gradient can be realized in a certain frequency range.The simulated results show that the FPA satisfies |S₁₁|<-10 dB in the frequency range of 10.52 GHz～10.898 GHz,the gain is 17.65 dBi at 10.7 GHz,and the corresponding aperture efficiency is 42.88%.Compared with the feed antenna only,the gain is increased by7.145 dB.更多还原
