868 MHz Antennas

What are 868 MHz antennas?

868 MHz antenna is a kind of radio wave transmission device working in an 868 MHz band, the working center frequency is 868 MHz, mainly used for wireless communication. Especially in the field of the Internet of Things (IoT), ISM, smart home, remote control, and so on.

868 MHz antenna working principle

In a wireless communication system, the antenna is responsible for transmitting RF signals from the transmitter and transmitting RF signals received from the receiver to the receiver.868 MHz antenna radiates the encoded RF signals at the transmitter, captures these signals, and decodes them into raw data at the receiver.

868 MHz antenna features and performance

Frequency Characteristics

The center operating frequency of 868 MHz antenna is 868 MHz and the bandwidth is usually 10 MHz. 868 MHz antenna is suitable for wireless communication applications in this frequency band.

Penetration ability

868 MHz belongs to the low-frequency band, 868 MHz antenna has strong penetration ability, can penetrate buildings and other obstacles, suitable for indoor and outdoor communication.

For example, advanced materials and technologies are used to improve antenna gain and efficiency; Antenna size and weight are reduced through optimized design; Easy to install, and maintain antenna solutions are developed.

What are the applications of 868 MHz antennas?

The main role of an 868 MHz antenna is used for wireless communication, which is widely used in the field of the Internet of Things, smart homes, remote controls, smart meters, medical equipment,t and so on.

868 MHz antenna belongs to low-frequency band RF communication technology, which is characterized by strong penetration ability and good anti-interference ability. In the 868 MHz band, multiple channels can be accommodated, allowing multiple devices to communicate simultaneously without interfering with each other. This antenna is commonly used in the following scenarios.

Internet of Things (IoT)

In IoT, the 868 MHz antenna is used to realize interconnection between smart home devices and support remote control and monitoring. For example, light control, temperature adjustment, curtain control, and other functions can be realized by an 868 MHz antenna.

LoRa

868 MHz LoRa antenna can enhance the signal receiving and transmitting ability of the LoRa module in the 868 MHz frequency band to improve the stability and reliability of communication. This is especially important in long-distance communication and low-power applications.

ISM

The 868 MHz ISM antennas are used in short-range, low-power wireless communication systems. The ISM (Industrial, Scientific, Medical) bands are frequency bands that have been set aside for RF uses other than telecommunication, and 868 MHz ISM antennas are commonly used for devices in these bands to enable license-free communication.

Especially in regions such as Europe, the 868 MHz band is widely used in license-free Industrial, Scientific, and Medical (ISM) band communications.

Smart home
