Abstract
A simple technique to design circular polarized microstrip patch antenna with broad bandwidth is presented. Two different feed mechanisms are designed to excite the dual orthogonal linearly polarized modes from a single radiating patch for the operated frequency band at around 2.4 GHz. One of the two modes is excited by an L-shaped probe, and the other is excited by an H-shaped aperture. The proposed design has a very simple antenna structure with an impedance bandwidth of 75.92% and a 3-dB axial ratio (AR) bandwidth of 49.89%. The −3 dB gain bandwidth is about 32%, and the peak gain is 8.42 dBi at around 2.4 GHz. Measured results of the fabricated antenna prototypes are also carried out to verify the simulation analysis.
