Title:
IMPEDANCE MATCHING APPARATUS AND ANTENNA
Document Type and Number:
WIPO Patent Application WO/2022/105075
Kind Code:
A1
Abstract:
Disclosed in the present application are an impedance matching apparatus and an antenna, comprising: a plurality of input terminals and a common output terminal disposed on a transmission line, wherein the plurality of input terminals are electrically connected to antenna radiators of different frequency bands, respectively, and the common output terminal is configured to combine antenna signals of different frequency bands in the transmission line and output same. For any input terminal in the plurality of input terminals, the distance between the input terminal and the common output terminal on the transmission line implements impedance matching between output impedance, at the common output terminal, of the antenna radiator electrically connected to the input terminal and characteristic impedance of a feed radio frequency system, so that the output impedance of the antenna radiator at the common output terminal matches the characteristic impedance of a feed line, the antenna radiators of different frequency bands are ensured to work at the same time, the use of a matching circuit is reduced, and the difficulty in realizing working of antenna radiators of different frequency bands is reduced.
