一款适用于CNSS及GNSS的双频圆极化天线
内容简介:介绍了一款适用于北斗导航卫星系统(CNSS)以及格罗纳斯导航卫星系统(GNSS)的天线.该天线为双频圆极化层叠贴片天线,可覆盖1258.52~1278.52MHz(133频段)以及1575~1609MHz(B1—2/L1频段).仿真结果显示,在B3频段和B1—2/L1频段,该天线为右旋圆极化(RHCP),法线方向轴比均小于1.5,增益可分别达4.6dB和4.7dB,驻波比分别小于1.4和1.1.
Abstract:A dual-band circularly polarized stacked patch antenna for Compass(Beidou) Navigation Satellite System (CNSS) and Glonass Navigation Satellite System(GNSS ) is presented in this paper. The antenna can cover both 1258.52 MHz-1278.52 MHz (133 band) and 1 575-1 609 MHz (B1-2/L1 band). The results of simulation show that: at B3 band and B1-2/L1 band, the antenna is right-hand circularly polarized (RHCP), the axial ratios of normal line direction are both less than 1.5, the gains are 4. 6 dB and 4. 7 dB respectively, and the VSWR are less than 1.4 and 1.1 respectively.
