Summary:
Microstrip patch antennas (MSAs) are used in various applications because of their attractive properties such as low profile, light weight, and easy fabrication. Since the miniaturization of antennas is necessary for wireless systems, several methods to miniaturize MSAs have been proposed, such as shorted-MSAs (quarter-wave MSAs) [1] and making a slit on the patch conductor [2]. However, these methods cannot be applied to dual-polarized MSAs. In this paper, a dual-polarized MSA miniaturized by bending the patch conductor and placing grounded conductors on the ground plane is presented. Matching stubs are incorporated in the patch conductor to improve its impedance bandwidth. The calculation results shown in this paper are obtained by a standard finite-difference time-domain (FDTD) method.
