Abstract

The invention relates to a patch antenna, a radiation unit and a feed structure. The feed structure comprises first feed bodies which are arranged in a central symmetry mode relative to the geometriccenter of the feed structure; each first feed body comprises at least two first bodies and second bodies, an included angle is formed between each first body and the corresponding second body, and every two adjacent first bodies are connected through one second body. And the feed structure is not easy to generate secondary radiation, so that the radiation unit is ensured to have excellent directional diagram characteristics.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a patch antenna, a radiation unit and a feeding structure. Background technique [0002] With the rapid development of mobile communication technology, higher and higher requirements are put forward for the relevant performance of the antenna. The patch antenna in the form of four-point feed has been widely used in the field of mobile communication because of its good array pattern characteristics. For patch antennas with four-point feed, the traditional feed structure is four-point probe feed or four-point coupled feed, which can easily cause secondary radiation and affect the pattern characteristics of the patch antenna. Contents of the invention [0003] Based on this, it is necessary to provide a patch antenna, a radiation unit and a feed structure for the problem of easily causing secondary radiation and affecting the antenna pattern characteristics. [0004...
