Abstract :
A hybrid dielectric resonator with patch antenna is investigated in this paper. The design employed the dielectric-resonator-on-patch (DRoP) concept by using the proximity coupling to reduce the total size occupied and increase the bandwidth of the antenna. Computer Simulation Technology (CST) Microwave Studio is used to design and simulate the hybrid antenna. In this paper two resonant frequencies which is from the dielectric resonator and the patch antenna are combined to have a wider bandwidth. The hybrid antenna managed to obtain a wider bandwidth of 49.88% (0.8 - 1.2 GHz). The compact design and wideband features of this antenna make it a suitable choice for UHF band applications such as RFID and digital TV.
