Radio frequency antenna

Abstract

The invention relates to a radio frequency antenna which comprises a polyhedron structure and a plurality of metamaterial radio frequency antennas, wherein the plurality of metamaterial radio frequency antennas are attached to the polyhedron structure; each metamaterial radio frequency antenna comprises an attaching medium, a feeder and a metal sheet, wherein the metal sheet is arranged on one surface of the attaching medium; the feeder is fed into the metal sheet in a coupling mode; and a micro groove structure is hollowed out on the metal sheet. According to the radio frequency antenna, the plurality of metamaterial radio frequency antennas are arranged on side surfaces of the polyhedron, so that the metamaterial radio frequency antennas on the side surface of the polyhedron can independently cover specific areas; and by designing the directional characteristics, gains and the like of each metamaterial radio frequency antenna, good signal coverage within a certain space or a whole space can be realized, and the overall radiation efficiency of a radio frequency antenna can be improved greatly.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, relates to a radio frequency antenna. Background technique [0002] With the high development of semiconductor technology, higher and higher requirements are put forward for the integration of today's electronic systems, and the miniaturization of devices has become a technical issue of great concern to the entire industry. However, unlike the development of IC chips following "Moore's Law", radio frequency modules, another important component of electronic systems, face the difficult technical challenge of device miniaturization. The radio frequency module mainly includes main components such as frequency mixing, power amplifier, filter, radio frequency signal transmission, matching network and antenna. Among them, the antenna is the radiating unit and receiving device of the final radio frequency signal, and its working characteristics will directly affect the working p...

Problems solved by technology

However, the impedance matching network additionally increases the feeder design of the electronic system and increases the area of ​​the radio frequency system. At the same time, the matching network also introduces a lot of energy loss, which is difficult to meet the system design requirements of low power consumption.
