Embodiment Construction
[0030] The smart antenna-based WIFI terminal equipment of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:
[0031] The metamaterial antenna is designed based on artificial electromagnetic material technology. Artificial electromagnetic material refers to a topological metal structure carved into a specific shape of a metal sheet, and the topological metal structure of a specific shape is set on a basis of a certain dielectric constant and permeability. The equivalent special electromagnetic material processed and manufactured on the material, its performance parameters mainly depend on its sub-wavelength topological metal structure of specific shape. In the resonant frequency band, artificial electromagnetic materials usually exhibit high dispersion characteristics. In other words, the impedance, capacitive inductance, equivalent permittivity and magnetic permeability of the antenna will change drasti...

The invention relates to a wireless fidelity (WIFI) terminal device based on an intelligent antenna. The WIFI terminal device comprises a wireless access device main body and the antenna. The antenna is an intelligent antenna which is provided with a plurality of metamaterial antenna units, and each metamaterial antenna unit comprises a dielectric substrate, a metal structure, a feed line and a reference ground. The feed line is coupled with the metal structure in a mutual mode, and the reference ground comprises a first reference ground unit and a second reference ground unit which are respectively arranged on two opposite surfaces of the dielectric substrate. The first reference ground unit enables one end of the feed line to form a microstrip line. According to the WIFI terminal device based on the intelligent antenna, a topology form of the metal structure of the antenna and reasonable arrangement of the microstrip line are accurately controlled, so that required equivalent dielectric constant and magnetic conductivity distribution are obtained. The antenna is enabled to realize good impedance matching in work frequency channels, and energy transition is finished efficiently, an ideal radiation pattern is obtained, and gain is high. In addition, the antenna is small in occupied size, and therefore the WIFI terminal device is small in entire size, and low in environment requirements.
Description
technical field [0001] The present invention relates to the technical field of wireless access equipment, in particular to a WIFI terminal equipment based on a smart antenna. Background technique [0002] WIFI (wireless fidelity) is a flexible data communication system that can be implemented as an extension or replacement of a wired local area network (LAN). Typically, WIFI uses radio frequency (RF) technology to send and receive data over the air without relying on any physical connection. The transmitted data is superimposed on the wireless carrier so that it can be accurately extracted at the receiving end. Assuming that radio waves are transmitted on different radio frequencies, multiple wireless carriers exist in the same space at the same time without interfering with each other. To extract data, a wireless receiver tunes to one frequency and discards all other frequencies. [0003] In a typical WIFI system, the WIFI system usually includes an access point (AccessP...
