Ferrite Loop Antenna Coil Description

Ferrite Loop Antenna Coil A ferrite loop antenna coil is a magnetic antenna component which uses ferrite core and wire winding to transmit or receive the electromagnetic signal. Compared with the conventional air-core antennas, the ferrite core can improve the magnetic permeability and concentration of magnetic flux to strengthen the signal sensitivity. Ferrite loop antenna coils are widely used in AM radios, RFID systems, wireless communication equipment, sensors, IoT devices and industrial control systems. They are small in size, good in frequency characteristics and stable in performance, and can be used for the efficient reception of the electromagnetic signals. Custom ferrite loop antenna coils can be designed according to frequency range, inductance, size and electrical requirements.

How Does Ferrite Loop Antenna Coil Work?

How it works: The Ferrite Loop Antenna Coil converts the Electromagnetic waves into an electrical signal (by magnetic induction).

When radio frequency electromagnetic waves act on the antenna coil, they produce a changing magnetic field around the ferrite core. The ferrite core enhances the concentration of magnetic flux inside the coil winding, thus increasing the induced voltage and improving the receiving sensitivity.

Working process:

Reception of Signals

The external electromagnetic waves generate the change of magnetic flux around the antenna.

Concentration of magnetic flux

Ferrite core concentrates and intensifies the magnetic field in the coil.

Generation of voltage

The time-varying magnetic field generates an electrical signal in the copper winding.

Signal processing

The electronic circuit processes the received signal.

Ferrite loop antenna coils have directionality, high sensitivity and outstanding performance in small communication devices.
