HIGH-GAIN METAMATERIAL ANTENNA, WIRELESS ACCESS DEVICE, AND ROUTER

摘要

Disclosed are a high-gain metamaterial antenna, a wireless access device, and a router. The high-gain metamaterial antenna of the present invention comprises a dielectric substrate, a metal structure, a feeder cable, and a ground reference. The metal structure, the feeder cable, and the ground reference are all arranged on the dielectric substrate, where the feeder cable and the metal structure are coupled to each other. The ground reference comprises a first ground reference unit and a second ground reference unit respectively arranged on two opposite surfaces of the dielectric substrate. The first ground reference unit allows one end of the feeder cable to form a microstrip cable. The high-gain metamaterial antenna, the wireless access device, and the router of the present invention acquire a required equivalent dielectric constant and magnetic permeability distribution by controlling precisely the topological morphology of the antenna metal structure and by distributing rationally the microstrip cable, thus allowing for the antenna the implementation of improved impedance matching within an operating frequency band, completion with increased efficiency of energy conversion, acquisition of an ideal radiation pattern, a high-gain, and implementation of the miniaturization of the antenna under the premise of meeting communication device performance requirement.
