Abstract

The invention provides a high-performance, miniature and coaxial base station antenna. The high-performance miniature and coaxial base station antenna comprises an antenna radiation unit, wherein the antenna radiation unit comprises a high-frequency radiation unit and a low-frequency radiation unit, the high-frequency radiation unit comprises a radiation patch, a feeding structure and a peripheral metal wall, the low-frequency radiation unit comprises a radiation body, a reflection plate and a peripheral metal wall. In the high-performance, miniature, dual-frequency and coaxial base station antenna provided by the invention, the whole structure is more compact based on current reality demands of the base station antenna on wide frequency band, miniaturization and high performance, the dual-frequency band of the base station antenna can cover 2G / 3G / 4G mobile communication bands, and the base station antenna is compatible with favorable radiation property and circuit characteristic under coaxial and miniature conditions.

Description

technical field [0001] The invention relates to the field of wireless technology, in particular to a high-performance miniaturized coaxial base station antenna. Background technique [0002] The ease of integration of base station antennas, the effective use of base station space, and the realization of electromagnetic performance stability in complex environments are the main driving forces for the development of antenna miniaturization. However, most of the currently widely used tri-band antennas adopt a side-by-side scheme, that is, two columns of high-frequency antennas and one column of low-frequency antennas are arranged side by side. Such a structural design limits the miniaturization of the antenna array. There are a lot of literature on terminal miniaturization and multi-band antennas at home and abroad. Through searching the existing technologies, it is found such as the article published on 2011-12-25 in information technology: the impact of miniaturized base stat...
