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.
Especially in the design room, the directional antenna gain cannot meet people's needs very well, and the directivity is not strong enough

Embodiment Construction

[0037] Metamaterials are artificial metal conductive sheets with a certain pattern and shape arranged on a dielectric substrate in a specific way. The different pattern shapes and arrangements of the artificial metal conductive sheets make the metamaterials have different dielectric constants and different magnetic permeability, so that the metamaterials have different electromagnetic responses. Wherein, when the artificial metal conductive sheet is in the resonant frequency band, the artificial metal conductive sheet will exhibit a high degree of dispersion characteristics. The so-called high dispersion characteristics refer to the impedance, capacitive inductance, and equivalent dielectric constant of the artificial metal conductive sheet. And the magnetic permeability will change drastically with the frequency.

[0038] The present invention utilizes the above principles to design a multi-mode working antenna device. It attaches the conductive sheet to the dielectric subst...

Abstract

The invention discloses an antenna device. The antenna device comprises an array type antenna, a power divider and a reflector unit, wherein the array type antenna comprises a plurality of antenna units; each antenna unit comprises a conductive slice engraved with grooved topological patterns, conductive feeder points and feeder lines; the power divider is used for dividing a baseband signal into a plurality of weighted value signals, and then respectively transmitting each weighted value signal to each antenna unit arranged in the form of an array by each conductive feeder point; the reflecting unit is used for reflecting backward radiator electromagnetic wave of the plurality of antenna units; the antenna units are arrayed, and phases of the antenna units are superposed by a beam-forming method, so that the directivity of the antenna is designed according to requirements; a reflecting metal plate is additionally arranged on the back surface of the antenna, so that a back lobe of the antenna is compressed, thereby achieving high directivity by a small antenna array, and replacing an existing indoor directional antenna.

Description

technical field [0001] The invention relates to an antenna device. 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 performance of the entire electronic system. However, important indicators ...
