Document Type and Number:
WIPO Patent Application WO/2023/108626
Kind Code:
A1
Abstract:
A phased array antenna, a scanning method therefor, and an antenna system. The phased array antenna comprises a plurality of antenna elements and a liquid crystal phase shifter used for performing phase calibration on the plurality of antenna elements. The scanning method comprises: applying a first wave control voltage to the liquid crystal phase shifter, and detecting first received signal level values received by the plurality of antenna elements; and continuously adjusting the first wave control voltage by means of an artificial intelligence algorithm, and detecting second received signal level values received by the plurality of antenna elements, until the ratios of the first received signal level values to the second received signal level values are greater than or equal to a first threshold.
