11δ mode and is confirmed by the rotation of the electric field inside the triangular DRA. This proposed antenna is realized by using dual right-angled triangular dielectric resonators (DRs), which are separated by an optimal gap to be responsible for the generation of wideband CP bandwidth. Proposed antenna shows -10 dB input impedance bandwidth of 20.22% (3.25-3.98 GHz) and 3-dB axial ratio bandwidth in broadside direction of 16.11% (3.31-3.89 GHz). In addition, this antenna offers an average gain and radiation efficiency of 5.64 dBi and 89.00% in the broadside direction respectively. The designed antenna shows right-hand circular polarization and is suitable for Wi-MAX applications (3.3-3.7 GHz).">
