METAMATERIAL RADIO FREQUENCY ANTENNA AND MIMO ANTENNA

摘要

The present invention relates to an antenna, comprising a feeder line, a first metal sheet, and a second metal sheet disposed opposite to the first metal sheet. The feeder line is fed into the first metal sheet by coupling, and the second metal sheet is electrically connected to the feeder line. A micro-groove structure is formed on the first metal sheet or the first metal sheet is formed of a metal wire with an artificial metal micro-structure. The present invention further provides an MIMO antenna and a metamaterial radio frequency antenna. The present invention avoids a complicated impedance matching network, and has advantages of small size, simple manufacturing, and low costs. Further, the present invention may further simplify the structure of the feeder line and reduce the consumption of the feeder line when the antenna is at a low working frequency band, and improve the performance of the antenna at the low working frequency band.
