Meanwhile, in order to adapt to a complex and variable application scenario, effectively improve the multipath effect in propagation and increase the channel communication capacity, the development of multi-polarization antennas (dual polarization, circular polarization and triple polarization antennas) is particularly important. At present, in order to meet the requirement of a 5G new frequency band on wide bandwidth, the traditional dual-polarized base station antenna generally adopts the schemes of a cross dipole pair antenna with a reflection floor, a magnetoelectric dipole antenna, a slot antenna with a reflection cavity and the like, so that the traditional dual-polarized base station antenna has the defects of large antenna size (half-wavelength limitation), high antenna profile (quarter-wavelength limitation and the like) and the like, and cannot be effectively applied to a microcell transmitting end with limited space such as indoor space. In order to meet the requirement of wide bandwidth, a conventional circularly polarized antenna usually adopts a cross dipole pair circularly polarized antenna, a multimode circularly polarized patch antenna and a circularly polarized antenna with broadband feed, but the conventional circularly polarized antenna has the problem of large antenna size. The traditional triple polarized antenna adopts a triple polarized antenna with a substrate integrated waveguide loaded with orthogonal dipoles and a triple polarized antenna with a patch loaded with the orthogonal dipoles, and has the defects of large antenna size, high antenna profile and narrow bandwidth. The substrate integrated waveguide and the triple polarized antenna loaded by the double polarized patch have the problems of large size and the like. The traditional miniaturized antenna usually adopts methods of loading a high dielectric constant substrate, slotting the surface of the antenna, bending the length of the antenna and the like, and the miniaturized antenna has the problems of narrow working bandwidth, large antenna loss and poor antenna radiation performance. Therefore, the miniaturized multi-polarization antenna developed by the traditional technology still has difficulty in meeting the requirement of 5G wide-band communication.
In summary, the conventional multi-polarization antenna for 5G new frequency band and sub 6GHz applications has the disadvantages of large size, limited bandwidth, low radiation efficiency, and the like, and is difficult to be applied to the antenna application requirements of indoor and other miniaturized systems.
