Abstract

In this communication, a dual-sense dual-polarized hybrid rectangular dielectric resonator antenna (RDRA) is explored. Two leading aims of the present article include: (i) to obtain dual-polarization characteristics i.e. the combination of linear and circular polarizations; (ii) to achieve quad-band features by using the concept of hybrid antenna. Modified printed line is used to excite dual radiating modes in RDRA i.e. TE^x_δ11 and TE^y_1δ1. In order to authenticate the proposed radiator, archetype of the proposed antenna is fabricated and tested. Good accord is established between measured and simulated outcomes. The proposed radiator is operated over four different frequency bands i.e. 1.81 GHz-2.06 GHz, 2.37 GHz --2.7 GHz, 3.35 GHz -- 4.4 GHz, and 4.62 GHz -- 5.62 GHz. Left Hand Circularly Polarized (LHCP) and Right Hand Circularly Polarized (RHCP) waves are obtained form 4.1-4.39 GHz and 4.78-5.2 GHz respectively. All these properties of the proposed radiator make it appropriate for 3G/WLAN/WiMAX applications.
