Abstract :
A truncated pyramidal circularly polarized dielectric resonator antenna (DRA) with a parasitic element is proposed to improve the performance of the axial ratio in the wide-angle region. The axial ratio for the angle alpha is analyzed by using FEM and over broad-angle region of 124deg axial ratio less than 3 dB is obtained
