Title:
LENS ANTENNA, DETECTION APPARATUS, AND COMMUNICATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/179322
Kind Code:
A1
Abstract:
Provided are a lens antenna, a detection apparatus, and a communication apparatus. The lens antenna comprises a feed source, a radio-frequency switch, at least two narrow-beam radiation units and at least two wide-beam radiation units, wherein the feed source can selectively feed any narrow-beam radiation unit or wide-beam radiation unit by means of the radio-frequency switch; the radio-frequency switch can connect the narrow-beam radiation units or the wide-beam radiation units to the feed source by means of switching; a first radiation area of each wide-beam radiation unit covers a second radiation area of each narrow-beam radiation unit; each wide-beam radiation unit comprises a plurality of sub-radiation units; and the plurality of sub-radiation units are connected to the radio-frequency switch by means of power dividers, so as to form wide beams by means of radiation of the plurality of sub-radiation units. In the technical solution, switching between a narrow beam and a wide beam can be achieved by means of the radio-frequency switch. When scanning needs to be performed, the wide beam can be used, and when communication needs to be performed for a specific area, switching to the narrow beam can be performed, thereby improving the detection effect of the detection apparatus.
