Dual‐polarised triple‐band multi‐beam multiple input multiple output (MIMO) antennas are evaluated for wireless local area network/worldwide interoperability for microwave access (WLAN/WiMAX) access points. The dual‐polarised antenna consists of two identical crossed triple‐band dipoles each of which is printed on each side of a square substrate, forming a compact planar configuration. The triple‐band dual‐polarised antenna is placed above a metal reflector to achieve high gain and directional radiation patterns. Measured results show that the dual‐polarised triple‐band antenna covers the WLAN 2.4‐GHz band, WiMAX 3.5‐GHz band, and WLAN 5‐GHz bands with return loss >10 dB and isolation >20 dB. An eight‐port MIMO antenna, a four‐beam MIMO antenna and a 32‐port four‐beam MIMO antenna are investigated for high‐capacity and wide‐coverage wireless applications in high‐density environment.
