The 868MHz helical antennas are high-performance copper spring helix antennas working in the 868 MHz RF band antennas manufactured by C&T RF Antennas Inc. for IoT and M2M applications.
In the wireless module, common 868 MHz spring helical antennas are made by the material of gold-plated spring antennas, copper spring antennas, nickel-plated spring antennas, and so on.
The 868MHz spring antenna is an essential part of wireless communication; its role is to radiate and receive radio waves. When transmitting, it converts high-frequency current into electromagnetic waves; When receiving, it converts electromagnetic waves into high-frequency currents.
Besides the High-performance 868MHz helical antennas, we also provide 433MHz spring antennas, 915MHz helical antennas, 868/915MHz spring antennas, 3G GSM spring antennas, WiFi helical antennas, 4G NB-IoT LTE-M helical antennas, GPS/GNSS spring antennas, and 315MHz spring antennas for your choice.
