Problems solved by technology

However, due to the frequency bandwidth used, the phase slope difference between the high frequency and low frequency of the cable network is large, and it is difficult to achieve accurate phase compensation, which leads to the sacrifice of the antenna gain of the array and the shape distortion of the vertical plane. It is not suitable for use, and it will complicate the array structure of the entire antenna, which is not conducive to optimizing production assembly

Description

technical field [0001] The invention relates to an ultra-wideband dual-polarized radiation unit and an interleaved array antenna, belonging to the field of mobile communication base station antennas. Background technique [0002] With the rapid development of mobile communication technology and the coexistence of multiple systems and systems, the requirements for base station array antennas are getting higher and higher, and antenna integration and broadband have become the development trend. In the common frequency band of dual-polarized directional base station array antennas, the working frequency of DCS network is 1710MHz~1800MHz; the working frequency of PCS is 1850MHz~1990MHz; the working frequency of UMTS is 1920MHz~2170MHz; In reality, there is a need for ultra-broadband antennas (relative bandwidth 44.9%) that can fully cover the working frequency of 1710MHz ~ 2700MHz, which can cover all the above network standards and meet the requirements of broadband and versati...
