This paper examines a triple band cylindrical dielectric resonator antenna (CDRA) with three different radiating modes, i.e., HEM118, TM018, and HEM128. Excitation of all these radiating modes simultaneously, in CDRA, is the most challenging task, which have been accomplished by using composite feeding structure [combination of vertical strip and psi-shaped (ψ) microstrip line]. Out of three radiating mode, two hybrid modes (i.e., HEM118 and HEM128) radiate in broadside direction, while remaining one (TM018) creates monopole like radiation pattern. Diversified radiation patterns make the proposed CDRA suitable for different wireless applications. Simulated outcomes of the proposed antenna design have been practically confirmed with the help of archetype of proposed antenna. The proposed CDRA is working in three different frequency bands: 2.5-3.02, 3.76-3.86, and 4.38-4.72 GHz. The proposed radiator is quite suitable for WiMAX (2.5 GHz) and vehicular applications.
