Bluetooth antenna implementation on an attachment module
Soo Liam Ooi · 2004
Three Bluetooth antenna structures were proposed. These antennas were designed for a small PCB inside an auxiliary attachment. These antennas are simple structures to implement and provide reasonably good performance. Tuning is achieved by adjusting the feeding and the lengths of the structures. The amount of coupling is also characterized. The choice of antenna is determined by the desired matched bandwidth, the amount of coupling tolerable, cost and the availability of board space and volume.
