Title:
SMART ANTENNA, ANTENNA FEEDER SYSTEM, ANTENNA COMMUNICATION SYSTEM AND AP
Document Type and Number:
WIPO Patent Application WO/2020/191610
Kind Code:
A1
Abstract:
Disclosed are a smart antenna, an antenna feeder system, an antenna communication system and an AP, belonging to the technical field of communications. The smart antenna comprises: an antenna element array and an impedance conversion circuit, wherein a feed end of the antenna element array is connected to a first end of the impedance conversion circuit, a second end of the impedance conversion circuit is an input end of the smart antenna, and the input end of the smart antenna is connected to a feeder; the antenna element array can form multiple different beam shapes, and in the multiple different beam shapes, input impedances of the feed end of the antenna element array are different; and the impedance conversion circuit is used for converting different input impedances of the feed end of the antenna element array into a preset input impedance at the input end of the smart antenna, and the difference value between the preset input impedance and a characteristic impedance of the feeder is less than a preset numerical value. The present application can effectively ensure a relatively large operation bandwidth of a smart antenna.
