Problems solved by technology

The single-feed method uses the degenerate mode separation unit to generate two radiating orthogonally polarized degenerate modes. It has a simple structure, low cost, and is suitable for miniaturization, but has narrow bandwidth and poor circular polarization performance; the multi-feed method requires Use the feed network to realize the quadrature feeding of the radiating patch with equal amplitude and 90° phase difference.

Abstract

The invention relates to the technical field of an antenna and particularly relates to a micro antenna for 5G mobile communication. The micro antenna comprises a metal reflection plate, a dielectric substrate, a metal square cut angle radiant patch, a metal rectangular radiation patch, a first metallized through hole, a first metal disc, a flanged fixed connector, a second metalized through hole and a short-circuit metal column, wherein the flanged fixed connector is coupled with the first metal disc through the first metallized through hole for feeding, and the short-circuit metal column penetrates through the second metalized through hole. The micro antenna is advantaged in that a coupling feeding mode is employed, the excellent impedance characteristic of the antenna is realized, the antenna standing-wave ratio is improved, work band width of the antenna is enhanced, the structure is simple and compact, the profile is low, and the antenna is easy to process.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a miniaturized antenna for 5G mobile communications. Background technique [0002] With the large-scale commercial use of 4G, 5G has become the focus of the current mobile communication industry. 5G frequency planning consists of low-frequency bands and high-frequency bands. Among them, low-frequency bands (below 6GHz) are still the core frequency bands of 5G systems due to good propagation characteristics. The above spectrum resources are very rich, therefore, the use of low frequency bands will become a future development trend, with many advantages, such as: very sufficient available bandwidth, miniaturization of equipment and antennas, and high antenna gain. As the core technology of 5G, the massive MIMO technology is basically characterized by configuring a large number of antenna arrays (from tens to hundreds) on the base station side, and using the principle of space divi...
