摘要

提出了一种带环形开环的宽带圆极化单极天线。通过在环路上引入间隙,该天线具有宽带特性并产生双向CP辐射。仿真结果表明,该天线具有宽带CP特性,在2.7 ~ 7.7 GHz范围内阻抗带宽$\mathbf{S11 < -10 dB}$为96.1%,在2.7 ~ 6.4 GHz频率范围内3db轴比(AR)带宽为81.3%。

Broadband Circularly Polarized Monopole Antenna with an Open loop
A broadband circularly polarized (CP) monopole antenna with an annular open-loop is presented. By introducing an gap on the loop, the presented antenna features broadband and produces a bidirectional CP radiation. The simulated results show that the proposed antenna has the advantage of broadband CP characteristics in terms of an impedance bandwidth with $\mathbf{S11 < -10 dB}$ of 96.1% from 2.7 to 7.7 GHz and a 3-dB axial ratio (AR) bandwidth of 81.3% in the frequency range of 2.7 to 6.4 GHz.
