摘要：

This paper introduces a square slot antenna with circular polarization and dual-band capability. The structure of the antenna is similar to an L-shape patch but with modifications in the lower rectangular part of the L, the patch has been transformed into a circle. Additionally, two strips having rectangular shape are located on the ground plane at opposite corners. By adjusting the size of the rectangular strips, the antenna can achieve dual-band and dual-sense circular polarization. The measured results of this design indicate that the Impedance Bandwidths are 45.16% (2.4-3.8 GHz) and 43.75% (5-7.8 GHz), while the Axial Ratio Bandwidths are 45.16% (2.4-3.8 GHz) and 37.4% (5-7.3 GHz) for the lower and upper bands respectively.
