Abstract :
We have proposed to place an 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. In this paper, we fabricate a 2×2 circularly polarized patch array in an area of 5 mm square on a silicon chip and have coaxial-line connection with a separated quadrature oscillator chip sized by 1 mm square. Then we measure characteristics of the antenna chip.
