An on-chip dipole antenna for millimeter-wave transmitters

Abstract

This paper presents an on-chip dipole antenna that radiates power directly from the die at millimeter-wave frequencies. To improve the transmission efficiency, a rectangular silicon ldquolensrdquo is attached on top of the chip. This increases the antenna gain in the upward direction by 8~13 dB, while suppressing backside radiation. A 28-GHz prototype CMOS transmitter has been demonstrated by integrating this antenna with a standing-wave oscillator.
