Abstract

This article proposes an impressive design of a circular polarized square slot antenna (CPSSA). The proposed single layer antenna composed of a square ground plane embedded with three unequal sized inverted-L strips around corners, which are capable of generating a resonant mode for exciting two orthogonal E vectors. Compared to the previous similar CPSSA designs, the axial-ratio bandwidth of the antenna is increased, more than two times. The designed CPSS antenna with its compact 40 × 40 × 0.8 mm ³ size operates over the frequency band between 2.63 and 6.38 GHz for VSWR<2 exhibiting a 71.11% (3-6.1 GHz) circular polarization (CP) bandwidth. Throughout this letter, the improvement process of the axial ratio and S ₁₁ properties are presented and discussed in detailed.
