A 60-GHz LTCC rectangular dielectric resonator antenna design with characteristic modes theory

In this study, the theory of characteristic modes is used as the first time for the analysis and design of a wideband rectangular dielectric resonator antenna. The rectangular dieletric resonator antenna was excited by a microstrip feeder with a rectangular coupled slot. The antenna is designed for low-temperature co-fired ceramic fabrication, with Ferro A6-M material and for ISM-band at 60GHz. The proposed antenna has an impedance bandwidth of 33% for S
