High Precision Copper Antenna Wire Forming Spring For Precision Parts

In the field of wireless communication, the spring antenna plays a very important role and is often used with the wireless module in many projects.

First, the role of the spring antenna
Spring antenna is a very important part in wireless communication. Its function is to radiate and receive radio waves. When transmitted, high-frequency current is converted into electromagnetic waves; When received, the electromagnetic waves are converted into high-frequency current. In simple terms, it is receiving the transmitting signal.
Two, spring antenna classification
1, according to the frequency classification: 315MHz spring antenna, 433MHz spring antenna, 868/915mhz spring antenna, 470/490mhz spring antenna.
2, according to the material classification: gold-plated spring antenna, copper spring antenna, nickel plating spring antenna.
Three, what are the advantages and disadvantages of the spring antenna
Advantages: the cost of spring antenna is relatively low compared with other antennas, and the size is small, easy to install, the antenna standing wave ratio performance is good, has a good anti-vibration anti-aging ability. The wireless module and antenna can be used together to make the wireless transmission distance longer.
Disadvantages: its gain is relatively small, and not waterproof, generally used as a built-in antenna.
General wireless modules use antennas: spring antenna, rod antenna, sucker antenna, sucker antenna is relatively more expensive than spring and rod antenna. When choosing the antenna, we mainly look at the frequency, gain, impedance, standing wave ratio, material, size and other parameters are in line with their needs.
