Abstract

This paper presents a millimeter-wave (mm-wave) pulse generator (PG) integrated with a new dipole-patch antenna in a 65-nm CMOS process for short range and portable active imaging applications. The integrated wide-band dipole-patch antenna is a combination of two type of radiators, patch and dipole, to exploit both advantages of the two antenna types. The {Mathematical expression} dipole-patch antenna in the top metal layer of the 65-nm CMOS process has a wide 30.2-GHz bandwidth from 73.9 to 104.1 GHz with minimum reflection coefficient of -29 dB at 101.6 GHz and resistance from 27.3 to 47.5 {Mathematical expression} by simulation in Momentum, ADS 2009. We proposed a resistor-less mm-wave damping PG whose peak-to-peak pulse output is 1.66-V with 9.1-ps duration in HSPICE simulation at the antenna input terminals. Radiation measurements by using a horn antenna and a Schottky diode placed at a 39-mm distance from the chip's surface show the main beam's peak at θ max = 17° with a half-power beam-width (HPBW) of 9° and the second beam's peak at θ sec = -23°. Maximum radiated powers in horizontal and vertical planes are respectively 2.4 and 0.5 μW.
