Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to an AMC-based low-profile broadband base station antenna and communication equipment. Background technique [0002] The base station antenna is the core part of the mobile base station, and its performance directly affects the quality of the entire communication system. With the continuous development of mobile communication technology, the complexity of the communication system is also increasing. Due to the long-term coexistence of multiple mobile communication standards, the space for base station applications is tight, and the base station antenna technology is constantly developing towards broadband and miniaturization. [0003] For traditional reflector-based base station antennas, according to the mirror image principle, the dipole needs to be placed at a height of λ / 4 from the reflector to ensure the consistency of its current and obtain good performance. At...
