Bluetooth Antennas

What are Bluetooth antennas?

Bluetooth antenna is an important component used to transmit and receive electromagnetic wave energy in the wireless communication system, which is responsible for converting wireless signals into electrical signals, thus ensuring the normal communication of Bluetooth devices.

The main role of the Bluetooth antenna is to help the Bluetooth module realize the transmission and reception of wireless signals, which directly affects the transmission characteristics of the Bluetooth module.

What are the types of Bluetooth antennas?

Types and characteristics of Bluetooth antennas.

Bluetooth ceramic antennas

The Bluetooth ceramic antenna is suitable for miniaturized design, divided into block ceramic antenna and multi-layer ceramic antenna. Block antenna is sintered by the high temperature of the whole ceramic body after printing the metal part, while the multilayer antenna is sintered by low temperature co-fired multilayer ceramic iterative pressure and then high-temperature sintering, which has the characteristics of small size and good concealment. Due to the high dielectric constant of ceramics, the antenna size can be effectively reduced.

Bluetooth PCB antennas

Integrated into the PCB board, has the advantages of less space occupation, low cost, and not easy to damage, but the signal transmission efficiency is low, easily to interfere with the motherboard.

External Bluetooth antennas

As the interface between an RF circuit and antenna, it has the advantages of good signal directionality, strong anti-interference ability, and high efficiency, but the cost is higher and the assembly is complicated.
