Problems solved by technology

However, when antennas working in different frequency bands are fused together, due to mutual coupling, impedance matching, port isolation and radiation performance deteriorate
Through the use of filtering antenna, choke ring loading and frequency selective surface technology, the common-aperture fusion of dual-frequency antennas has been realized, but most of the fusion antennas have a narrow frequency band, which is of limited help to solve the problem of the tense plane of the base station antenna; It can better improve the problem of shortage of antenna resources, and there is an urgent need to study the integration of antennas with wider frequency bands

Embodiment 1

[0036] Such as figure 1 and figure 2 As shown, a broadband dual-frequency fusion antenna based on a reflective surface includes a metasurface structure 1, a low-frequency antenna radiation unit 2, a high-frequency antenna radiation unit 3, and a reflector 4. There are four high-frequency antenna radiation units in the form of Arranged in a 2*2 equidistant array, set above the reflector through support columns, the distance between adjacent high-frequency antenna radiation units is 126mm, and the distance from the reflector is 44mm. The low-frequency antenna radiating unit is arranged above the high-frequency antenna radiating unit, and the metasurface structure is located above the high-frequency antenna radiating unit.

[0037] The low-frequency antenna radiating unit is arranged above the high-frequency antenna radiating unit. Since the low-frequency antenna radiating unit is an electrically large-sized shield relative to the high-frequency antenna radiating unit, the low-...
