The common LoRa antenna types include spring antennas, PCB, FPC, Ipex SMA antennas, and fiberglass antennas. Depending on the power and frequency range of the LoRa module, different antennas can be selected to match.
For 100mW LoRa module, you can choose a spring antenna, PCB antenna, or FPC antenna.
Above 500mW module can choose SMA rubber duck antenna.
Above 2W module can choose the magnetic mount antenna, glass fiber antenna.
LoRa antennas generally have a range of frequency bands that they support, if use the band out of the range, the antenna performance will be degraded to a certain extent. Therefore, when using, you should try to make the device work in the supported frequency band, in order to achieve the best transmission effect.
Generally speaking, the gain of suction cup magnetic mount antenna is higher than that of rubber duck antenna and spring antenna.
In a communication system, the strength of the gain will interfere with the ability of the antenna to radiate or receive wireless signals; all things being equal, the higher the gain, the further the wireless signal will travel.
Therefore, to improve the communication distance of the wireless module, it is also a good idea to choose a high gain antenna.
