Spring antenna action

Spring antenna is a very important part in wireless communication, its role is to radiate and receive radio waves. When transmitting, convert high-frequency current into electromagnetic wave; when receiving, convert electromagnetic wave into high-frequency current. Simply put, it is to accept the transmitted signal.

Spring antenna classification

1. Classified by frequency: 315MHz spring antenna, 433MHz spring antenna, 868 / 915MHz spring antenna, 470 / 490MHz spring antenna.

2. Classified by material: gold-plated spring antenna, copper spring antenna, nickel-plated spring antenna.

What are the advantages and disadvantages of spring antenna

Advantage: The cost of the spring antenna is lower than other antennas, and the size is small, easy to install, the antenna standing wave ratio performance is good, and has good anti-vibration and anti-aging capabilities. The wireless module is used in conjunction with the antenna to make the wireless transmission distance farther.

Disadvantages: its gain is relatively small, and it is not waterproof, generally used as a built-in antenna.
Generally, the antennas used in wireless modules are: spring antennas, rod antennas, and sucker antennas. The sucker antennas are relatively more expensive than springs and rod antennas. When choosing an antenna, it depends on whether the parameters such as frequency, gain, impedance, standing wave ratio, material, and size meet your needs.

1. Tips for spring antenna selection

Spring antennas can be divided into nickel-plated, gold-plated and copper spring antennas according to their materials. Generally, there are 315/490/868 / 915MHz spring antennas according to frequency. Selection skills: When choosing a spring antenna, you can see its size, length, gain, impedance, material, frequency, standing wave ratio and other parameters according to the actual project requirements.

2. Tips for rod antenna selection

According to the connection method of the antenna head, the rod antenna can be divided into: straight rod antenna, elbow rod antenna, folded rod antenna; according to the material classification: gold plated, nickel plated rod antenna. Selection skills: According to the module frequency used in the project, you can choose the rod antenna of the corresponding frequency, and pay attention to whether the length of the rod antenna, the connection method of the antenna head, the material, gain, impedance, standing wave ratio, etc. match.

3. Suction cup antenna selection skills

According to the frequency, it can be divided into 315/433/490/868 / 915MHz sucker antenna and 2.4G small sucker antenna. Selection skills: If the power of the module is more than 2W, it is recommended to choose a suction cup antenna, and whether the project is waterproof, considering the parameters of cable length, input impedance, standing wave ratio, gain, suction cup size and other parameters.
