Both the alpha coil and the inductor coil of low-orbit satellite are inductive antennas, but they are different in structure, working principle and application.

structure

An alpha coil consists of one or more conductive coils, which are usually wound around a cylindrical or square skeleton. The inductance of a low-orbit satellite consists of one or more conductive rings, which are usually arranged on a plane.

Working principle

The alpha coil is emitted by using an electric current to create a magnetic field in the coil, which radiates radio waves. The receiving principle of Alpha coil is to use a magnetic field to induce a current in the coil.

The principle of launching inductors in low-orbit satellites is to use current to generate electric fields in coils, which radiate radio waves. The receiving principle of inductance of low-orbit satellite is to use electric field to induce current in the coil.

Apply

Alpha coils are mainly used for short-range radio communication, such as radio remote control, radio transmission and radio identification.

Low-orbit satellite inductors are mainly used for satellite communications, such as satellite phones, satellite television and satellite navigation.

Sum up

Both the alpha coil and the low orbit satellite inductance are inductive antennas, and each has its own advantages and disadvantages. Alpha coils are suitable for short range radio communication, while low orbit satellite inductors are suitable for satellite communication. In practical applications, alpha coils and low-orbit satellite inductors can be used in complementary ways. For example, in a satellite communication system, an alpha coil can be used at a ground station to receive satellite signals, while a low-orbit satellite inductor can be used on a satellite to transmit signals.

According to the needs of customers, Ju Yeda has developed two kinds of inductance winding equipment, DCW-01SCW, which can quickly produce inductance coils of low-orbit satellites, and DCW-01HCW, which can automatically wind alpha inductance coils, greatly reducing direct labor hours and manufacturing costs.
