Tri-band compact antenna array for MIMO user mobile terminals at GSM 1800 and WLAN bands

摘要

Multiple-Input Multiple-Output (MIMO) systems have been widely studied in recent years as a solution to improve the radio link reliability. To introduce MIMO in mobile communications, it is necessary to design antennas with differential features to introduce multiple elements in the space reserved for the antenna, such as the type of element or array configuration. In this article, a 2 _ 2 MIMO system has been considered according to the next-generation WLAN (802.11n) frequencies band.
