- Abstract
In this paper, a novel broadband circular polarized (CP) antenna for mobile communication is proposed. The antenna is constructed by a square ring patch with a gap and coplanar waveguide (CPW) feed structure. To achieve a broadband CP wave, a cross patch is embedded at the center of the slotted square ring patch to excite two orthogonal resonant modes with equal amplitude and 90° phase difference for CP radiation. Furthermore, on one side of ground a stub is embedded to match impedance bandwidth that can cover the whole CP bandwidth completely. Loading the AMC (Artificial magnetic conductor) structure on the back of the antenna achieves directed radiation of circular polarized waves. An antenna was fabricated based on simulation and optimization. The simulated and measured results show that the bandwidth with S11 < -10 dB is 66.9% from 1.82 GHz to 3.65GHz, and the 3 dB axial ratio bandwidth is 52.8% from 1.95GHz ~ 3.35 GHz.
