【摘要】 本文提出了一种基于天线集成技术的多频段共口径圆极化天线。通过在双频段层叠圆极化微带天线上集成一副交叉偶极子天线,使得该天线实现多频段圆极化性能。基于此天线集成技术的多频段共口径圆极化天线能够在北斗频段(1268.52±10.23MHz、1615.68±5MHz、2491.75±5MHz)&天通频段(1980-2010MHz、2170-2200MHz)实现宽波束圆极化性能,同时,在北斗3个频段内,VSWR<1.5,在天通三个频带内VSWR<2。更多还原

【Abstract】 A multi-band shared aperture circularly antenna based on antenna integration technology is propose d in this paper. By integrating a cross dipole antenna on a dual-band stacked circularly polarized microstrip an tenna, a multi-band circularly p-olarized antenna can be realized.The multi-band shared aperture circularly ant enna based on antenna integration technology can realize circularly polarized in Beidou(1.268GHz,1.615GHz,2.492GHz)&Tiantong(1.980GHz-2.010GHz,2.170GHz-2.200GH-z),with VSWR<1.5 at 3 operate frequency b ands(Beidou),and VSWR<2 at 2operate frequency bands(Tiantong).更多还原
