A Broadband Circularly Polarized Wide-Slot Antenna with a Miniaturized Footprint

Abstract

This letter presents a novel and simple feeding technique for exciting orthogonal components in a wide-slot antenna. In this technique, a rectangular bracket-shape parasitic strip is placed at the open end of the straight microstrip line to excite the fundamental horizontal and vertical components of the circular polarization (CP). The proposed technique—when employed in conjunction with the asymmetrical geometry of coplanar waveguide (CPW) and a protruded stub from the ground plane—permits for maintaining axial ratio (AR) below 3 dB within a wide range in the C-band as well as a compact footprint of the antenna. All geometry parameters of the antenna are adjusted through rigorous EM-driven optimization to obtain the best performance in terms of footprint, impedance matching, and axial ratio bandwidth (ARBW). The size of the proposed antenna is only 27 mm × 28.8 mm. The structure features a 62 percent impedance bandwidth (3.6 GHz-6.85 GHz) and ARBW of approximately 49 percent (3.6 GHz to 5.93 GHz) with the average realized gain of 3.3 dB within the CP operating band. Numerical results are validated experimentally. Close agreement between simulation and measurement results has been observed.
