Embodiment Construction
[0038] The technical solutions in the embodiments of the present invention will be clearly described below with reference to the drawings in the embodiments of the present invention.
[0039] The invention relates to a reconfigurable antenna, and also provides a mobile terminal using the reconfigurable antenna. The mobile terminal can be used in the fields of radar, aerospace, wireless and satellite communication networks and the like. The invention relates to a dual polarization pattern or a reconstructed antenna array, which is designed based on the Yagi antenna principle and the microstrip line principle. In one embodiment, the reconfigurable antenna of the present invention includes two antenna units, and each antenna unit is a ±45° dual-polarization pattern reconfigurable antenna unit. Of course, the reconfigurable antenna of the present invention may also include only one antenna unit. The specific structure is introduced as follows.

The invention relates to a reconfigurable antenna. The reconfigurable antenna comprises a feed layer, a first dielectric layer, a grounding layer and a second dielectric layer which are stacked in sequence, wherein the feed layer is coupled with the grounding layer; the reconfigurable antenna also comprises an excitation unit which is arranged on one side, far from the grounding layer, of the second dielectric layer, a pair of first parasitic units and a pair of patches; the pair of the first parasitic units are distributed on the two sides of the excitation unit in a first direction, and a gap is formed between each of the first parasitic units and the excitation unit separately; the pair of the patches are distributed on the two sides of the excitation unit in a second direction, and a gap is formed between each of the patches and the excitation unit separately; the first direction is perpendicular to the second direction; each of the first parasitic units and the grounding layer are connected through a short circuit assembly and a switch assembly separately; and the pair of patches are used for improving the isolation degree of the reconfigurable antenna. The invention also relates to a mobile terminal. The reconfigurable antenna disclosed by the invention is high in isolation degree.
Description
technical field [0001] The present invention relates to antenna technology in the field of wireless communication, in particular to a reconfigurable antenna and a mobile terminal using the reconfigurable antenna. Background technique [0002] In the field of wireless communication, miniaturization, multi-function, broadband, and large capacity have become the directions that the industry is striving to pursue. As spectrum resources become increasingly tight, the number of users in a cell increases rapidly, and the problems of numerous wireless interference sources become more and more serious, traditional single-function antennas cannot meet the needs of today's wireless communications. As an important branch of the reconfigurable antenna, the pattern reconfigurable antenna can adjust the radiation beam so that the radiation zero point is aligned with the interference source, and the radiation main beam direction is aligned with the target user, thereby reducing interference...
