Abstract

In this article, dual mode triple band hybrid cylindrical dielectric resonator antenna CDRA for different wireless applications is investigated. It is seen that annular ring shaped patch along with T-shaped printed line behaves as a magnetic and electric dipole concurrently and create HE11I´ and HE12I´ mode in the proposed CDRA. Both of the hybrid modes radiate in broadside direction. The concept of hybrid antenna the combination of annular ring patch and CDRA is used to achieve triple-band feature in the proposed antenna. Ansoft HFSS-EM simulator is used to optimize the proposed antenna. Optimized simulated results have been practically confirmed by using the archetype of proposed antenna. The proposed radiator is applicable in three different frequency bands, that is, 2.24-2.56 GHz, 3.28-4.18 GHz, and 5.36-5.8 GHz. It is appropriate for WLAN 2.4/5.8 GHz and WiMAX 2.5/3.3/5.5 GHz applications.
