RF signal is ease to be interfered, which makes the signal of transmitting and receiving impure to impact on wireless communication. It is not to be ignored for interfering between transceiver signals in package of transceiver, thus, insulating enough must be taken. In addition, the mount of noise introduced through a main interference source being from contribution of digital signal continuously...
In this communication, we introduce a high-sensitivity antenna system for Bluetooth headsets dealing with the numerous and unidentified noises in a printed circuit board (PCB). This antenna system is composed of a ground radiation antenna for Bluetooth applications and an adjacent slot for noise suppression. A loop-type circuit is used to model a noise source on the PCB to provide wide-frequency spectrum...
