Selection of Spring Antenna
Release time:
2024-11-28
Spring antenna is a very common low-cost antenna widely used in many electronic products. Spring antennas have been widely used in both Lora and sub-1g frequency bands such as 433M, 470M, and 915M, as well as mobile cellular network frequency bands such as NBIOT and GSM. However, in practical applications, we have found that many customers do not know how to choose and use spring antennas.

However, in practical applications, we have found that many customers do not know how to choose and use spring antennas.
When choosing a spring antenna, many companies will purchase some samples and directly weld them onto their own products to start using them. Then they will ship the selected spring antenna products to the OEM factory, simply telling the manufacturer where the antenna is welded.
Today we will analyze and explain the usage and purchase issues of this spring antenna.
Selection of Spring Antenna
Spring antennas cannot be used directly by purchasing existing products. This is because the characteristics of the antenna determine that it will exhibit completely different performance and frequencies in different states. For example, if you need a 433MHz spring antenna, but the nominal 433MHz spring antenna you purchased directly from the market and welded onto your product does not perform as 433MHz. The frequency of the antenna has changed on your product, and it may be operating at 370MHz or 500MHz. The actual resonant frequency of this antenna is unknown at this time. So many people may find that the nominal frequency of the antenna they purchase is consistent with what their product needs, but the performance does not meet expectations when actually used. This is actually a normal phenomenon.
