Evaluation of a 60 GHz compact-range gigabit wireless access system using a large array antenna
2014
A novel compact-range gigabit wireless access system in the 60 GHz band is proposed for burst-type data transfer. A large array antenna adopted in the access point forms a stable communication zone proportional to the antenna size. The mobile user standing everywhere within the coverage, receives a stable signal almost free of multi-path. The circularly-polarized waveguide slot arrays with different numbers of elements are realized for demonstrations. A RF front-end and a BB module are integrated on the backside of those antennas to construct the prototype of a compact-range Gigabit wireless access system. The system performance, especially the bit-error rate is evaluated as the function of relative positions between transmitter and receiver.
