Antenna structure and preparation method thereof

Abstract

The invention provides an antenna structure and a preparation method thereof. The antenna structure comprises a low-loss dielectric substrate layer, an interconnection line located at the bottom of the low-loss dielectric substrate layer, a plurality of antenna elements which are different in bands and patterns and located on the surface of the low-loss dielectric substrate layer, an anti-crosstalk medium layer, and a plurality of conductive through holes, wherein different antenna elements are filled with the anti-crosstalk medium layer, and the anti-crosstalk medium layer covers the surfacesof the antenna elements; the plurality of conductive through holes penetrate through the low-loss dielectric substrate layer; and each conductive through hole is correspondingly connected with one antenna element, wherein the top of each conductive through hole is connected with one end part of the corresponding antenna element and the bottom of each conductive through hole is connected with theinterconnection line. Integration of the multi-band antenna elements is achieved, and the waveband range detected by the antenna structure is expanded.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to an antenna structure and a preparation method thereof. Background technique [0002] With the popularization of mobile data devices such as smartphones and tablet computers, people are more eager to be able to connect to the Internet anywhere. In mobile data devices, the antenna is the only part that contacts the network, which requires mobile data devices to have different standards. Antennas connected to different wireless frequency bands. Antenna size is determined by operating bandwidth, operating frequency, and radiation efficiency. A larger antenna size can provide greater bandwidth and higher efficiency, and a larger antenna size can maintain the same radiation efficiency. [0003] However, existing mobile data devices are thinner and thinner, which leaves less and less space for antennas, which greatly limits the bandwidth and frequency of antennas, which also br...
