Abstract

A novel method to design a coplanar-waveguide-fed slot-coupled rectangular dielectric resonator antenna is presented in this paper. This study permits to optimize the adiation bandwidth in the same analysis process for both the dielectric and the slot. The complete antenna is designed for low-temperature co-fired ceramic fabrication. The goals are to fabricate all the antenna for low permittivity in the same process, to match the dielectric resonator to the coplanar-waveguide-fed line for the frequency range of ISM at 60 GHz. The obtained results show that the proposed antenna radiation bandwidth determined by -10 dB return loss can be as large as 14 GHz, more than 23% centered at about 60 GHz.
