Compact metamaterial quad-band antenna for mobile application

Abstract

In this paper, we presented two examples of compact quad-band antennas which are designed based on MTM technologytrade. These multi-band antennas not only occupy smaller volume than conventional antennas such as monopole and PIFA, but also provide equal or better performances. In addition, these Metmataterial antennas are easily printed on the product PCB board, thus significantly reducing the cost in the mass production. The antenna performances clearly demonstrate that the proposed antennas can satisfy the needs of the modern mobile device applications.
