摘要
This letter presents a new dual-band circularly polarized (CP) dielectric resonator antenna (DRA). The dual-band design utilizes the quasi-TE111 and -TE113 modes of the rectangular DRA, which is coupled by a simple underneath rectangular aperture. Two opposite corners of the DRA are removed at 45 degrees to obtain CP fields. A diagonal groove is introduced at the top face of the DRA to facilitate tuning of the DRA. A design guideline of the dual-band CP DRA is given. The reflection coefficient, radiation pattern, axial ratio, and antenna gain of the DRA are simulated and measured, with good agreement between them.
