Problems solved by technology

This technology is widely representative of the current dual-polarized omnidirectional antenna technology, and can realize the function of vertical / horizontal polarization. Its disadvantages are: the size of this type of antenna is large, the gain is about 2dBi, and it can only be used for indoor distribution. When the system does not require high antenna gain, it is impossible to realize the outdoor base station antenna designed as a high-gain parallel-fed array
This technology has two disadvantages. One is that in order to avoid the mutual influence of the two polarizations, the size of the antenna will be larger; the other is that although it can be made into a vertical / horizontal polarization antenna, it cannot achieve the ± 45° dual polarized antenna
[0005] In summary, the existing technology cannot solve the technical problems of broadband, high-gain, compact, high-isolation omnidirectional dual-polarized antenna

Abstract

The invention discloses a radiation unit which comprises a balun and a radiator which is fed and supported by the balun. The radiator comprises two half-wave vibrators which are orthogonally arranged. Each half-wave vibrator comprises two vibrator arms. Each vibrator arm is provided with a main pierced hole which is arranged on the symmetric axis of the vibrator arm. The size of the main pierced holes respectively belonging to the vibrator arms of different half-wave vibrators is different. Furthermore, the invention discloses a dual-polarized antenna which comprises at least one antenna reflecting plate and multiple radiation units which are arranged on the antenna reflecting plate. The aforementioned radiation unit is adopted. The dual-polarized antenna and the radiation unit thereof are high in cross polarization ratio and high in degree of isolation and gain and have great radiation characteristic.

Description

technical field [0001] The invention relates to a mobile communication antenna, in particular to a dual-polarization antenna and a radiation unit used in the antenna. Background technique [0002] In order to solve the multi-band, multi-standard, and complex interference problems brought about by multi-operator shared mobile communication systems, and to meet people's increasingly stringent requirements for electromagnetic pollution tolerance, broadband, high gain, miniaturization, and high isolation The demand for dual-polarized base station antennas is more urgent. [0003] The omnidirectional antenna has the advantages of omnidirectional radiation and convenient installation. It has special uses whether it is the rapid site deployment in the early stage of mobile communication system construction or the blindness and leak detection in the later stage of network optimization. In the past, omnidirectional base station antennas were mainly single-polarized, but modern mobil...
