摘要

提出了一种宽波束北斗导航天线。16条金属条均匀地包裹在圆极化微带天线周围。金属条激发的辐射可以扩大微带天线的波束宽度和AR波束宽度。在1.561 GHz时，天线主方向的RHCP增益为3.3 dBic。天线阻抗带宽(|S11|<−10 dB)为109 MHz (1.520 GHz-1.629 GHz)。3db轴向带宽为27mhz (1.549 GHz-1.576 GHz)。在xz面和yz面，3db波束宽度分别为112°和111°，3db AR波束宽度分别为162°和149°。因此，这种北斗导航天线具有宽波束。

Design of a wide beam BeiDou navigation antenna

A wide beam BeiDou navigation antenna is presented. The 16 metal strips are evenly put around the circularly polarized microstrip antenna. The radiation which metal strips excite can expand the beamwidth and AR beamwidth of the microstrip antenna. The RHCP gain of the antenna is 3.3 dBic in the main direction at 1.561 GHz. The impedance bandwidth (|S11|<−10 dB) of antenna is 109 MHz (1.520 GHz-1.629 GHz). And the 3-dB axial bandwidth is 27 MHz (1.549 GHz-1.576 GHz). In xoz-plane and yoz-plane, the 3-dB beamwidths are 112° and 111°, respectively, and the 3-dB AR beamwidths are 162° and 149°, respectively. Thus, this BeiDou navigation antenna has a wide beam.
