摘　　要：The shortcoming of Wi-Fi networks is that one user can access the router at a time.This drawback limits the system throughput and delay.This paper proposes a concept of Simultaneously Different Tx/Rx(SDTR)radiation patterns with only one antenna set at the router.Furthermore,these two patterns have to be simultaneously operated at the same time so that the system delay can be eased.An omni-directional pattern is employed at router for receiving mode so that the router can sense carrier signal from all directions.At the same time,the router launches a directional beam pointed to another user.A proposed circuit allows these two modes to be able to operate the same time.To evaluate the SDTR concept,a prototype is constructed for testing in real circumstance comparing to computer simulation.As a result,the SDTR concept can improve the system throughput while decreasing the system delay comparing to conventional system.
