Compact dual-band planar metamaterial antenna arrays for wireless LAN

The paper presents two examples of compact antenna arrays for MIMO applications which were designed based on MTM technologytrade. These multi-band antenna arrays occupy smaller volume than the conventional antennas while they provide equal or better performances. These antennas in addition to the excellent performance can be easily integrated with any PCB based circuit, thus significantly reducing the cost in the mass production. The compact antenna arrays can enable advanced MIMO solutions like switched arrays and beamforming arrays which can provide diversity gains in addition to MIMO gain.
