Bluetooth Antenna, is a must component to transmit and receive electromagnetic energy in wireless communication systems.
Bluetooth antenna is divided into the following antenna:
1) Dipole antenna
The dipole antenna is usually cylindrical or flaky, and has a swivel at the bottom of the antenna as a device for energy feed to connect with the adapter of the RF front-end circuit of the Bluetooth Module.
2) PIFA antenna
The PIFA antenna is named because of its side structure is similar with inverted English letters F appearance. The operating length of PIFA antenna is only a quarter of the operating wavelength. And it included the ground metal surface so it can reduce the sensitivity of the metal surface in the module, it is very suitable for use in the Bluetooth module device.
3) Ceramic antenna
The ceramic antenna is another miniaturized antenna which is suitable for use in Bluetooth devices.
