2.55 GHz miniaturised phased antenna array based on 7 nm-thick HfxZr1−xO2 ferroelectrics

A miniaturised phased array, suitable for a low-power wireless device and able to be fed from its battery, is experimentally demonstrated. The phase array consists in two gold patch antennas, phase shifters and additional circuitry, all integrated on HfxZr1−xO2/high-resistivity silicon 4 inch wafer....

Zusammenfassung:	A miniaturised phased array, suitable for a low-power wireless device and able to be fed from its battery, is experimentally demonstrated. The phase array consists in two gold patch antennas, phase shifters and additional circuitry, all integrated on HfxZr1−xO2/high-resistivity silicon 4 inch wafer. The radiation beam at 2.55 GHz is steered with 25° when the 7 nm-thick ferroelectric is biased with ±1 V.
