Abstract

We have developed new compact MIMO DRA for 802.11n system. The antenna has three independent orthogonal channels which can offer high efficiency and high diversity gain. The simulation result closely matches with measured result in S-parameter and radiation pattern. The new DRA antenna is compared with three spaced dipoles in a commercial 802.11n terminal in an office environment. The measurements show the compact DRA antenna has similar data throughput in NLOS case and better data throughput in LOS case due to his higher gain. All results show the usefulness of a very compact antenna solution to achieve very efficient antennas at the terminal of MIMO system. Further work is to reduce size of antenna and keep good performances.
