Abstract
A method and system provides a multiple input multiple output (MIMO) antenna arrangement in a wireless communication device. A first antenna element and a second antenna element co-located within a same antenna volume are respectively coupled to first and second antenna feeds proximate to a base perimeter segment of a device chassis. The first antenna feed is at a pre-calculated distance from the second antenna feed. The second antenna element, a first MIMO antenna, is coupled to an antenna ground positioned proximate to the first antenna feed and at a pre-determined distance from the second antenna feed. A third antenna element operating as a second MIMO antenna is placed proximate to a top perimeter segment of the device chassis. The antenna arrangement achieves (a) low correlation between the MIMO antennas and (b) an acceptable or pre-determined level of antenna isolation between the first antenna element and the second antenna element.
