A comparative study of WiMAX subscriber equipment antennas

While single antenna system performance can suffer in multipath environments multiple input multiple output (MIMO) antenna systems can take advantage of rich multipath and offer significant cost-performance benefits. Therefore, performance with MIMO systems has to be assessed referenced to the environment. This paper presents a study of WiMAX MIMO antenna modules in various environments. It is shown that lower gain antennas in rich multipath offer very cost efficient alternatives to higher gain antennas.
