Abstract :
An omnidirectional circularly polarized (CP) dielectric resonator antenna (DRA) with a parasitic patch loading on its top is investigated in this paper. It is found that the operating frequency of the antenna can be tuned by changing both the sizes of the patch and ground plane. The reflection coefficient, axial ratio (AR), radiation pattern and antenna gain of the proposed CP DRA are studied, and reasonable agreement between the measured and simulated results is observed.
