Broadband Dielectric Resonator Antenna Covering Multiple Millimeter-wave Frequency Bands

In era of the fifth-generation(5G) and beyond, millimeter wave (mm-Wave) techniques provide solutions for high data rate and large bandwidth [1]. The broadband mm-Wave antenna covering several frequency bands are crucial to wireless communication systems due to the limited footprint of the terminals. For broadband mm-Wave antenna designs, the losses should be as low as possible. This makes the dielectric resonator (DR) antenna (DRA) a good candidate for mm-wave antenna designs due to the compact size, low loss, high efficiency, and high degree of design flexibility [2], [3].
