Abstract

This paper presents the design of a 60-GHz CMOS integrated on- chip Yagi antenna with balun bandpass filter by using 90-nm CMOS technology. The Yagi antenna is fed by the balanced output of the balun bandpass filter, whose amplitude and phase differences between the balance ports from 57 to 64 GHz are within 1.3 dB and 180° ± 5°, respectively. The effect of the metallic plane of the probe station has been considered in the calculation of the antenna power gain from the Friis power transmission formula with two identical face-to-face antenna-balun-filters. The measured antenna-balun-filter power gain is - 12.4 dBi at 60 GHz.
