Low-cost, High-Gain Antenna Module Integrating a CMOS Frequency Multiplier Driver for Communications at D-band

This paper presents a compact D-band antenna module for ultrafast short-range communications. The system comprises a planar lens fed by an antenna-in-package embedding an integrated 28-nm bulk CMOS frequency multiplier. Both lens and primary source are fabricated using low-cost printed circuit board (PCB) technology. The module achieves a peak gain of 25 dBi and works between 114 GHz and 138 GHz with a gain drop lower than 3 dB. The proposed solution paves the way for low-loss and low-profile wireless systems entirely integrated in planar multilayer substrate modules.
