Abstract

The design of a novel microstrip-line fed circularly polarized (CP) annular-ring slot antenna (ARSA) is studied. To achieve CP radiation with broad axial ratio (AR) bandwidth that can cover both the WiMAX 2.3 GHz and WLAN 2.4 GHz bands, a simple method of loading an inverted L-shaped slot into the bottom section of the ARSA is proposed. Measured results show that the proposed antenna can exhibit wide 10-dB impedance bandwidth of 48% (1.69-2.76 GHz), and its corresponding 3-dB AR bandwidth was approximately 8% (2.29-2.48 GHz).
