What is a spring antenna?

A helical antenna spring coil antenna is a metal coil spring that is typically installed on the PCB board terminal.

Antenna spring mount, Material steel, copper, stainless steel.

The polarization electromagnetic signal rotating in the space can be transmitted. This antenna is usually used in a terrestrial station in satellite communication. With non-balanced feeders, such as shaft cables are connected to the antenna, the cable center is connected to the spiral portion of the antenna, and the outer skin of the cable is attached to the reflector.

What is the working principle of a spring antenna?

It can generally be considered that electromagnetic waves are moved at a speed of light at the metal helix spring coil.

Take a sping from I to II point, the required time is

T = πD / c

In terms of the helical antenna, its axial electromagnetic wave is only moving a pitch ρ, and its axial equivalent rate is

υ = ρ / t = ρ / c (πD)

υ = csin θ = cρ / (πd) ≤c

It can be seen from the above formula that is always less than or equal to C.

Therefore, the spiral antenna can slow the speed of electromagnetic wave movement, is a slow wave system, and its equivalent wavelength λ is equivalent to less than the working wavelength λ.

For the helical antenna, the resentment is resonant to its 1/4 equivalent wavelength, and thus the geometric length of the spiral antenna can be shortened.

An antenna spring is a coil spring withstanding pressure. Its material is mostly circular, also made of rectangular and multi-strand steel.

In general, the pitch of the spring is equal. The shape of the spring includes a cylinder, cone, ambiguous, concave, and a small amount of non-circular.

There is a certain gap between the compressed spring ring.
When subject to an external load, the antenna spring shrinks the deformation, and the stored energy will also change. The compression spring provides resistance to the external load.

The compression spring is typically wrapped in diameter such as a pitch steel wire and a fixed wire. The spring uses a plurality of open coils to provide resistance to the external load. They will be pushed backward in the action of external pressure.

Springs are typically wrapped in diameter with equal-pitch steel wires and fixed wires.

Mainly used in medical respiratory equipment, medical mobile devices, manual tools, home care equipment, shock absorbers, engine valve spring torsion springs, etc., a spring antenna is a mechanical part using elastic operation.
