RF Modeling and Measurement of a Novel Aperture-Coupled Hybrid Glass-Silicon 5G Antenna Array

In this work, the electromagnetic modelling and measurement of a novel aperture-coupled hybrid glass-silicon 1x2 antenna array is presented. The patch elements are located under a glass substrate, which is placed on a silicon layer. The antenna array is fed using aperture coupling. A cavity is etched in the silicon layer to reduce the impact of silicon, and thus ensures significant improvement of the antenna efficiency and gain. The proposed antenna was fabricated and measured. Very good correlation is obtained between simulation and measurement.
