Design of 60-GHz dual-polarization dielectric resonator antenna

A high gain 60-GHz on-chip dual-polarization dielectric resonator antenna (DRA) in silicon substrate based on Integrated Passive Device (IPD) technology is presented in the paper. In the proposed structure, dielectric resonator (DR) was fed by using wire-bond structures for bandwidth and antenna efficiency improvement. The Simulation and measurement regarding the antenna reflection coefficient and isolation are conducted for design validation. The measurement results show that the antenna can operate in 60-GHz band, and the impedance bandwidth with |S11| less than −10 dB is from 52.5 GHz to 63.5 GHz. The peak gain is 5.5 dBi. The proposed design is well suited for System-in-Package millimeter-wave radio front-ends.
