Problems solved by technology
Today's multi-standard fusion base station antennas are designed using the third-order intermodulation scheme, but due to the poor stability of the third-order intermodulation, it has become a technical bottleneck for multi-standard fusion base station antennas, restricting the development of this type of antenna industry The radiation unit is the core component of the multi-standard fusion base station antenna. The multi-standard fusion base station antenna integrates radiation units of more frequency bands in a limited space. However, due to the complex design of the radiation unit itself, the half-wave oscillators in each radiation unit The coaxial cable connection is used to connect the core wire and the outer conductor of the coaxial cable with the radiation arm of the half-wave vibrator by welding with an electric soldering iron to feed power to the dual machine. This method has complicated procedures and many solder joints. It affects the overall stability of the antenna, resulting in poor intermodulation stability of the antenna

The invention provides an antenna and a radiation unit adopted by the same. The radiation unit comprises a base, two pairs of half-wave vibrators arranged in a polarization orthogonality mode and a supporting piece used for supporting each half-wave vibrator, wherein each half-wave vibrator comprises two radiation arms arranged symmetrically; and two radiation arms of each half-wave oscillator are supported and fixed on the base by the supporting piece. The radiation unit is characterized in that a pair of half-wave oscillators adapted to each polarization is provided with a parallel feeder, and each parallel feeder is respectively coupled and connected with the two half-wave oscillators of the same polarization so as to feed an external signal to the radiation arms of the two half-wave oscillators. The radiation unit provided by the invention has no welding spot connection, is simple to assemble, and has relatively high intermodulation stability.
Description
technical field [0001] The invention relates to mobile communication antenna technology, in particular to a radiation unit. Background technique [0002] With the development of 5G communications, multi-standard integrated base station antennas are increasingly becoming the mainstream antennas used in the communications industry. Today's multi-standard fusion base station antennas are designed using the third-order intermodulation scheme, but due to the poor stability of the third-order intermodulation, it has become a technical bottleneck for multi-standard fusion base station antennas, restricting the development of this type of antenna industry The radiation unit is the core component of the multi-standard fusion base station antenna. The multi-standard fusion base station antenna integrates radiation units of more frequency bands in a limited space. However, due to the complex design of the radiation unit itself, the half-wave oscillators in each radiation unit The coax...
