Bluetooth Antenna Design and TestingBluetooth Antenna Design and TestingWhite PaperBluetooth Antenna Design and Testing1. INTRODUCTIONThis 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 ConsiderationsThe 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.2.2.RangeThe free-space path loss is expressed as follows, where S is the distanc……
