The first combiner 211 and the second combiner 221 are configured to combine the electrical signals of multiple frequency bands output by the first feed network 11 and/or the second feed network 12 into one signal, feed the one signal into the first radiation unit 311 or the second radiation unit 321, and transmit the antenna signal of the corresponding frequency band by the first radiation unit 311 or the second radiation unit 321 connected correspondingly, thereby implementing multi-frequency one-time deployment. The first feed network 11 and the second feed network 12 are used for outputting at least one electric signal of the same frequency band, so that two antenna coverage modes can be realized on a preset frequency band; further, the first feed network 11 is a 65 ° horizontal lobe width feed network, and the second feed network 12 is a multi-beam feed network, so that the 65 ° horizontal lobe width and multi-beam antenna signal coverage can be compatible at the same time on the same frequency band, and system capacity and site resource mitigation are effectively improved.
Although the embodiments of the present application have been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the embodiments of the present application.
