Problems solved by technology

At present, the bandwidth support of planar broadband base station antennas is difficult to achieve 65% and higher bandwidth coverage, especially it is difficult to maintain a stable radiation pattern and gain on 65% and higher bandwidth coverage; on the other hand, the miniaturization of broadband antennas is also Difficulties in design, usually the antenna size with 50% relative bandwidth coverage is basically larger than half of the wavelength corresponding to the center frequency of its working frequency band

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a broadband base station antenna and wireless communication equipment based on ring loading and slotting. Background technique [0002] As an important part of the mobile communication system, the base station antenna is the portal for direct communication between mobile terminals such as mobile phones and the base station, and is also an important carrier for the wireless communication system to realize frequency multiplexing, diversity reception and other technologies. With the development of mobile communication, multi-standard, multi-system and multi-frequency bands coexist. Mobile communication technology is developing towards high speed, large capacity, integration and miniaturization, so the design of miniaturized broadband base station antennas is particularly important. In addition, massive MIMO antennas are one of the important core technologies of current 5G, future...
