Description
Summary:The narrow band body centre network based on Bluetooth technology has been constructed by integrated planar inverted-F antenna and the communication channel character has been studied by measurement for wearable computer application. For Bluetooth system, the path loss of different antenna positions on body for measurement can range from -35 dB to -70 dB. If the two antenna located on the arms and moved the two arms, the path loss can change from -40.2 dB to -64.8 dB. The deep breath can affect the path loss within 5 dB and metal ornament such as metal ring can affect about 11.8 dB. The specific absorption rate distribution can also be studied by finite-difference time-domain (FDTD) method.
