Antenna Board

Antennas are very important for wireless transceiver modules. Their gaining effect can effectively improve the communication distance and quality of wireless transceiver modules, so antenna selection is also crucial.

There are many types of antennas, including built-in antennas and external antennas, as well as helical antennas, FPC antennas, rod antennas, and suction cup antennas.

Built-in antennas: Built-in antennas are usually directly soldered to the wireless transceiver module and then embedded in the device together with the module. The appearance of such devices is generally less affected, but they will affect signal reception to some extent (which generally does not affect device use). It is more suitable for enclosed places or scenarios where external antennas cannot be connected.

External antennas: External antennas are generally connected to the wireless transceiver module through a metal probe or a signal extension cable, and are not directly soldered to the device. Compared with built-in antennas, external antennas have better signal gain. External antennas can be installed in the sky.

External antennas do not have strict requirements on size. They are mainly rod antennas, suction cup antennas, and Yagi antennas.

Finally, the selection of the antenna for wireless modules should be based on the actual project requirements. The use of internal and external antennas is not absolute, and the actual application scenario should be the final determining factor. Antennas are an indispensable accessory for wireless modules. Choosing the right antenna can bring great benefits to a project.
