Metamaterial antenna and electronic equipment

Abstract

The invention provides a metamaterial antenna. The metamaterial antenna comprises an antenna unit, wherein the antenna unit comprises a dielectric substrate, a radiation unit, a feeder line, a feeding point, a feed wiring and grounding plate and a grounding point, the radiation unit is arranged on the surface of the dielectric substrate, the feeder line is coupled to the radiation unit, the feed wiring and grounding plate is electrically connected with the feeder line and the feeding point, the grounding point is electrically connected with a grounding plate, and the radiation unit comprises a sheet metal and a hollow groove formed on the sheet metal. According to the metamaterial antenna, due to the structural design, the performance requirement of the antenna is met; and moreover, the metamaterial antenna has high gain, the wireless data transmission requirement of electronic equipment employing a general packet radio service (GPRS) module can be met, and a low-loss antenna dielectric substrate is combined, so that the metamaterial antenna has high operating performance. According to the electronic equipment employing the metamaterial antenna, wireless signals can be well received and transmitted, and the wireless signal coverage requirement is met.
