Abstract

A new technique to design single-fed circularly polarized (CP) microstrip patch antenna is presented in this paper. The estimation of bandwidth enhancement is based on dimension adjustment of the fractal defected ground structure (FDGS). Then, by inserting circular slot on the patch, circular polarization (CP) is obtained. The parametric optimization is done in ANSYS HFSS simulator in order to fix the dimensions of the microstrip patch antenna. The microstrip patch antenna with third iterative FDGS is fabricated and measured. The bandwidth of the measured microstrip antenna with CP radiation is about 120 MHz (2.13–2.25 GHz) and axial ratio of 2.3 dB to ensure circular polarization.
