A kind of antenna and communication equipment

Abstract

The embodiment of the present invention provides an antenna and a communication device. The antenna comprises at least one active array module. The active array module comprises a plurality of activeintegrated antenna elements, wherein the active integrated antenna elements are provided with a first preset distance, and the active integrated antenna elements are provided with a filling medium between the active integrated antenna elements, the filling medium having a preset medium parameter. The preset medium parameter is determined according to a preset phase difference of a radiated wave between the first preset distance and an adjacent active integrated antenna element. The communication device includes an antenna. The antenna and the communication device provided by the embodiment ofthe invention not only ensures good radiation function, but also reduces the array volume of the antenna.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to an antenna and a communications device. Background technique [0002] With the rapid development of communication technology, the antenna is an important communication tool in the communication process, and people have higher and higher requirements for its communication performance and structural size. Therefore, the structure of the antenna should be reduced under the condition of ensuring communication performance. The issue of size is getting more and more attention. [0003] Under the current technical conditions, in order to effectively reduce the array volume of the existing 3D MIMO antenna, the microstrip patch array element is mainly used at present.

[0003] Under the current technical conditions, in order to effectively reduce the array volume of the existing 3D MIMO antenna, the microstrip patch array element is mainly used at present. However, because the microstrip antenna is a closed-end radiation reactive antenna, there is a Inherent defects such as frequency band, high Q value and low efficiency, while the open half-wave antenna has inherent advantages such as minimum impedance, pure resistance, no reactance, minimum reactive power loss, and maximum radiation power. The array composed of microstrip patches Compared with the 3D MIMO half-wave antenna array, the resulting beamforming, space diversity and space multiplexing have a large gap

Although the 3D MIMO half-wave antenna array has good radiation performance, the array element spacing needs to meet the coherent conditions in electromagnetic radiation, which increases the array volume of the antenna. If the array element spacing is reduced, the electromagnetic wave radiation of each array element will be affected. coherence condition
