摘要：
This paper proposes and analyses a circularly polarized square patch antenna with an improved axial ratio bandwidth covering a frequency of 1.665GHz to 1.845GHz. The antenna attains circular polarization using the perturbations truncated corners and well-shaped slots embedded on the patch. The results indicate that the antenna attains desirable axial ratio (below 3dB) for a wide elevation range of-134 degrees to 47 degrees. When compared to conventional truncated corner circularly polarized square patch antenna, the axial ratio bandwidth of the proposed antenna is increased by 30MHz. The antenna model is fabricated, tested and the measured results show a high correlation with the predicted ones.
