The use of Murata ceramic Bluetooth antenna for wrist device based on flexible printed circuit boards

Abstract

In this paper, the Murata ceramic Bluetooth antenna, which has been successfully used on rigid printed circuit boards, is now applied to flexible printed circuit boards. Based on this Bluetooth antenna, a novel wrist device that can be wirelessly connected to mobile phones is developed. In particular, to reduce the height of the wrist device, the ground-clearance type Murata Bluetooth antenna is adopted. It is demonstrated that the wrist device works very well in real environments.
