Bluetooth Antenna Design and Testing
1. INTRODUCTION
This white paper discusses guidelines for Bluetooth antenna design and testing. The areas of interest are antennae built into Bluetooth modules, PC accessories such as PCMCIA cards, USB dongle attachments, and Bluetooth units built into laptop PCs. Each configuration has different requirements and critical parameters that will be discussed in this paper.

2. ANTENNA DESIGN 2.1. General Design Considerations

The antenna should be placed high and away from metal or conductive objects. In addition, its position against the ground plane is important depending on how the antenna is fed from the RF circuits.

The free-space path loss is expressed as follows, where S is the distanc
