Patch antenna on a thick resin layer fed by coaxial-lines through a hole in a silicon chip in the 60GHz band

We have proposed to place a CMOS RF circuit and an antenna on each side of a silicon chip in the 60 GHz band, respectively, and to connect between them with low loss by a coaxial-line structure using a hole opening in the chip. To enhance the radiation efficiency, a patch antenna is placed on a thick resin layer. In this paper, we design a differential-feed square patch antenna on a silicon chip.
