Abstract :
In this paper, a new hybrid resonator is proposed, the proposed design uses three parts, a dielectric resonator (DR), an intermediate substrate and an aperture coupled feed. Furthermore a matching circuit is designed in order to offer a wide bandwidth. The slot aperture is used as a radiator and as a mechanism to couple the DR to the microstrip line. The intermediate substrate is used to isolate the resonator from the slot leading to a structure that is robust to resonator placement and adhesive thickness. It is also used to lower the permittivity of the dielectric resonator antenna (DRA) which increases the bandwidth. Simulation and experimental results including return loss, and radiation patterns are presented and discussed
