2.4 GHz Circularly polarized Microstrip Patch Antenna with Diagonal Structural Symmetry

In this paper, a single feed circularly polarized microstrip patch antenna has been presented. The proposed antenna geometry is a square shaped patch with all four corners are etched and exhibits diagonal symmetry. Antenna parameters are obtained using the electromagnetic simulation tool. The dependency of bandwidth, and radiation efficiency with respect to substrate thickness has been studied. The antenna parameters of the proposed structure are compared with the conventional antenna structure.
