Disclosed in the invention is an antenna combiner having high performances. The antenna combiner comprises a plurality of band-pass filters, an electronic switch and a combiner module. The combiner module consists of a low-pass filter and a high-pass filter. The output terminal of the low-pass filter is connected with the output terminal of the low-pass filter; and a wiring terminal after connection is used as an output terminal of the antenna combiner and is used for connecting an antenna. Among the multiple band-pass filters, the output terminal of the band-pass filter with the central operating frequency less than a designated frequency is connected to the input terminal of the low-pass filter in the combiner module by the electronic switch; and the output terminal of the band-pass filter with the central operating frequency larger than the designated frequency is connected to the input terminal of the high-pass filter in the combiner module by the electronic switch.
