Abstract

The present application provides an antenna and an array antenna. The antenna of the present application includes: a first radiating element and a second radiating element, the first radiating element is surrounded by four dipoles, the second radiating element is a radiating unit arranged inside the first radiating element; the first radiating element The second radiating element is used for supporting the transmitting frequency band, and the second radiating element is used for supporting the receiving frequency band; or, the first radiating element is used for supporting the receiving frequency band, and the second radiating element is used for supporting the transmitting frequency band. This application realizes the physical separation of the transmission path and the reception path with a simplified feed network design.

Description

technical field [0001] The present application relates to communication technology, and in particular to an antenna and an array antenna. Background technique [0002] The base station antenna can use one antenna to receive and transmit signals in multiple different frequency bands through wideband design, and separate the signals between different frequency bands through filters or combiners. If the distance between the two frequency bands is relatively close, the filter or combiner The suppression of the device puts forward higher requirements. Therefore, independent antennas can be used for each frequency band, and a certain isolation is designed between antennas in different frequency bands, thereby reducing the suppression requirements for filters or combiners, and simplifying filter design. [0003] However, at present, in order to realize the separation of the transmitting frequency band and the receiving frequency band in the array antenna, the usually designed arra...
