Silicon integrated dielectric resonator antenna solution for 60GHz front-end modules

A new dielectric resonator antenna (DRA) solution for the complete integration of radio front end at 60GHz is presented. The solution is a SoC configuration consisting of an integrated PA and a CPW fed slot on 65nm CMOS SOI (Silicon on Insulator) technology from ST Microelectronics. A co-design strategy is taken into consideration to reduce the size of the system and matching circuit losses. A total size of 1mm
²
die has been achieved for both PA and Antenna excitation element. The antenna element as a whole is then taken from this SoC solution into a SiP configuration which can integrate the DR and silicon based elements, achieving a high gain (5dBi) and a bandwidth of 5GHz in the specified band.
