Speaking of Bluetooth modules, there is one thing that must be mentioned, and that is the antenna. What is the antenna? An antenna is a component used to transmit or receive electromagnetic waves.

The main function of the transmitting antenna is to effectively convert the high-frequency current energy of the transmitter into electromagnetic energy in space; while the function of the receiving antenna is exactly the opposite.

Therefore, the antenna can essentially be said to be an energy converter.

Anyone who knows Bluetooth should know that the Bluetooth module can successfully complete short-distance data transmission regardless of the location or direction of use.

But proper Bluetooth antenna design will help achieve better transmission quality.

For example, let’s compare the two common antennas for Bluetooth modules currently on the market: IPEX interface external antenna and PCB onboard antenna.

IPEX interface external antenna, its advantages are: good signal directionality, high efficiency, strong anti-interference ability, and can stay away from interference on the motherboard.

And there is no need to do too much debugging and matching. As a terminal manufacturer, you only need to connect an IPEX antenna to the outside. Of course, there are also disadvantages: high cost and troublesome assembly.

PCB board-mounted antenna, its advantages are: low cost, no need to assemble the antenna separately, not easy to be damaged by touch and easy to assemble, but there are gains and losses -----

PCB antennas are susceptible to interference on the motherboard and are relatively inefficient, sacrificing performance.

Note: Because short-range data transmission itself is relatively stable, the antenna on the Bluetooth module actually has the same effect when it is close.

But if the distance is long, an external antenna will have obvious advantages.

As a well-known Bluetooth module supplier in China, Shenzhen Jinhangbiao Electronics Co., Ltd. is deeply involved in the BLE market and has launched a variety of Bluetooth modules.

For example, Bluetooth 4.2BLE module with IPEX interface external antenna: HY-40R204I. TI's CC2640R2F solution is used.
