Abstract

ABSTRACT In this letter, a design of dual-circularly-polarised series-fed truncated corner patch antenna is proposed. This low-profile antenna consists of a 4 4 radiative truncated corner square shape array patches and two non-radiative substrate integrated waveguide (SIW) power-dividers. Moreover, using two perpendicular network feeds can help to generate right-hand and left-hand circular polarisations with two distinguished ports. The antenna operates with acceptable radiation characteristics in which the reflection coefficient is less than −10 dB from 11.7 to 12.2 GHz. Hence, the operating bandwidth of this antenna is about 500 MHz. To verify the simulated results, a prototype of this antenna is fabricated and measured. Simulation and measurement results prove that the proposed antenna can be a good candidate for satellite communication.

一种紧凑的RHCP和LHCP截断角贴片串联馈电阵列天线

摘要本文提出了一种双圆极化串联馈电截角贴片天线的设计方案。这种低剖面天线由4个4辐射截角方形阵列贴片和两个非辐射衬底集成波导（SIW）功率分配器组成。此外，使用两个垂直的网络馈送可以帮助生成具有两个不同端口的右手和左手圆极化。天线工作时具有可接受的辐射特性，其中11.7至12.2 GHz的反射系数小于−10 dB。因此，该天线的工作带宽约为500MHz。为了验证仿真结果，制作并测量了该天线的原型。仿真和测量结果表明，该天线是一种很好的卫星通信候选天线。
