摘要

本文提出了一种采用接近耦合馈源的低轮廓圆极化贴片天线。利用宽带移相网络的四个近距离耦合馈源激励贴片天线，实现了宽带带宽。−10 dB |S11|带宽范围为1480 ~ 2730 MHz (58.4%)， 3db轴比带宽范围为1650 ~ 2820 MHz(52.4%)。仿真结果表明，天线在2000 MHz宽方向上的峰值增益为4.4 dBi。这是在保持非常低的0.05λ的情况下实现的，其中λ是与最低工作频率对应的波长。天线整体尺寸为75.0 mm × 75.0 mm × 9.2 mm。

Wideband Proximity-Fed Low Profile Circularly Polarized Patch Antenna

This paper presents a low profile, circularly polarized patch antenna using proximity coupled feeds. A wide bandwidth was achieved by exciting the patch antenna with four proximity coupled feeds from a wideband phase shifting network. The simulated −10 dB |S11| bandwidth was from 1480 MHz to 2730 MHz (58.4%) and the simulated 3 dB axial ratio bandwidth was from 1650 MHz to 2820 MHz (52.4%). The peak gain of the antenna was simulated to be 4.4 dBi at 2000 MHz in the broadside direction. This was achieved while maintaining a very low profile of 0.05λ, where λ is the wavelength corresponding to the lowest operating frequency. The overall antenna dimensions were 75.0 mm × 75.0 mm × 9.2 mm.
