Manufacture and Performance of a 60GHz-Band High-Efficiency Antenna with a Thick Resin Layer and the Feed through a Hole in a Silicon Chip

Abstract

As a first step towards the realization of high-efficiency on-chip antennas for 60 GHz-band wireless personal area networks, this paper proposes the fabrication of a patch antenna placed on a 200 mu m thick dielectric resin and fed through a hole in a silicon chip. Despite the large tan 5 of the adopted material (0.015 at 50 GHz), the thick resin reduces the conductor loss at the radiating element and a radiation efficiency of 78%, which includes the connecting loss from the bottom is predicted by simulation. This calculated value is verified in the millimeter-wave band by experiments in a reverberation chamber. Six stirrers are installed, one on each wall in the chamber, to create a statistical Rayleigh environment. The manufactured prototype antenna with a test jig demonstrates the radiation efficiency of 75% in the reverberation chamber. This agrees well with the simulated value of 76%, while the statistical measurement uncertainty of our handmade reverberation chamber is calculated as +/- 0.14 dB.
