摘要

提出了一种用于无线应用的2×2宽带圆极化(CP)天线阵列的设计，该天线阵列在2.4 GHz的s波段内谐振。为了实现宽带操作，在天线阵贴片几何结构中嵌入多个可变长度的插槽。单个阵列贴片由功率分配器电路产生的微带馈线激发。整个进给结构采用序相(SP) 00、90、180、2700设计。所提出的多槽阵列结构具有宽阻抗和高增益的轴比带宽等优点。- 10db反射系数带宽为86% (1.68 GHz-4.22 GHz)， 3db轴比带宽为29% (2.99 GHz-4.02GHz)。在工作区域获得了增益大于10dbi的良好辐射特性。

Broadband circularly polarized antenna array for S-band wireless applications

A design of 2×2 broadband circularly polarized (CP) antenna array is proposed to resonate within S-band at 2.4 GHz for wireless applications. To realize broadband operation, multiple slots of variable length are embedded in antenna array patch geometry. The individual array patch is excited by microstrip feed lines, which are derived from power divider circuits. The whole feeding structure is designed with sequential phase (SP) of 00, 90, 180 and 2700. The proposed multi-slot array structure gives the advantage of being wide impedance and axial ratio bandwidth with high gain. The -10 dB reflection coefficient bandwidth and 3 dB axial ratio (AR) bandwidth are 86% (1.68 GHz-4.22 GHz) and 29% (2.99 GHz-4.02GHz), respectively. Good radiation characteristics with gain more than 10 dBi in the operating region are obtained.
