Abstract

This paper presents a dualband circularly polarized (CP) rectangular dielectric resonator (DR) antenna (DRA). Its fundamental TE111 mode and higher-order TE113 mode are excited simultaneously to obtain two working bands. The dimensions of the dual-band DRA are calculated by solving simplified formulas of the dual-mode rectangular DRA. To generate circularly polarized fields, two asymmetric diagonal L-shaped slots are etched on the ground plane to excite two degenerate orthogonal modes in each band, giving a CP dualband antenna. For demonstration, a dual-band dual-sense CP antenna working in GPS L1 band (1.575 GHz) and 2.4 GHz WLAN band are designed using ANSYS HFSS. Its reflection coefficient, axial ratio (AR), antenna gain, and radiation pattern are studied. The antenna radiates right- and left-hand circularly polarized fields in the lower and upper bands, respectively.
