Abstract

A thin dual band circularly polarized (CP) patch antenna with a wide 3-dB axial ratio beamwidth (ARBW) is presented for BeiDou Navigation System (BDS) application. The CP radiation is achieved using simple stacked square patches for dual band radiation in the BDS B1 band (1561±2 MHz) and B3 band (1268±10 MHz). A `string moon' type branch extension technique is proposed to enhance the ARBW and axial ratio bandwidth in both operating bands. Loading 30° gap-type annular parasitic metal strips (APMS) further improves the ARBW in both operating bands. The experimental results show that the impedance bandwidth of the antenna is 6.3% (1.25-1.33 GHz) and 4.5% (1.52-1.59 GHz), and the axial ratio bandwidth is 1.6% (1.26-1.28 GHz) and 1.2% (1.55-1.57 GHz), respectively. In addition, the 3-dB ARBWs in the φ=0° and φ=90° planes are 185° and 184° at 1.268 GHz, respectively; and 222° and 211° at 1.561 GHz, respectively. The simulated results are in good agreement with the measured ones.
