Abstract :
An efficient on-chip antenna structure in CMOS technology for system in package integration is presented. The antenna consists of a slot radiator on the top metal layer of the technology coupled to a rectangular dielectric resonator above the slot. The cavity backed slot configuration is used to isolate the antenna from the substrate. This configuration blocks the antenna interference through the substrate to the other RF circuits on the same substrate. Radiation efficiency of about 40% is achieved on a lossy silicon substrate without removing the lossy silicon under the antenna
