Original Abstract

The combination of two higher order hybrid electromagnetic modes (HEM133 and HEM123) in a simple cylindrical dielectric resonator is exploited in the presented paper to enhance antenna gain. Both modes were excited by the same feeding aperture in the ground plane of a microstrip line. A linearly polarized, broadside radiation pattern with maximum realized gain of about 11.6 dBi was successfully obtained. The antenna was designed for the ISM band with central frequency 5.8 GHz and relative bandwidth at least 2.6 %. For fabrication, we used a layered Arlon AR600 substrate of relative permittivity 6.15. Experimental results showed reasonable agreement with simulations and validated the new concept of the high gain dielectric resonator antenna.
