Results are presented from measurements to identify the benefit of using two intelligent quadrifilar helix antennas (IQHAs) in a WLAN access point to enhance the MIMO capacity of a 4x4 MIMO link by using antenna selection. Indoor measurements at 2.3GHz were undertaken using a channel sounder and two transmit IQHAs with one receive. Results indicate that there is a marked increase in capacity potential while still using only four transceivers at both ends and it opens the scope for increased capacity with small antennas.
