Can I use an external GPRS antenna for my bluetooth device to extend range area of bluetooth? I have a Bleugiga WT11 bluetooth device.
Two parameter of antenna which are important are
- Frequency range
Frequency range of antenna which is shown with antenna's frequency present center frequency of antenna and it's bandwidth and Impedance which is used for preventing losses of traveling wave travels through the device and antenna. Your Bluetooth modules run in 2 GHz band and GPRS is used in 900 MHz and sometimes 1800 MHz. GPRS antenna is modified for these frequency and it will has low gain in 2 GHz. Also it is hard to match impedance for 2 GHz. So, it is not suitable to use for Bluetooth. But i recommend see antenna specification and your Bluetooth band. If your antenna has gain in Bluetooth band with considering impedance it could be used.
