Ferrite-Rod Antenna

ferrite-rod antenna

[′fe‚rīt ¦räd an′ten·ə] (electromagnetism) An antenna consisting of a coil wound on a rod of ferrite; used in place of a loop antenna in radio receivers. Also known as ferrod; loopstick antenna.

Ferrite-Rod Antenna

 

a magnetic antenna with a core consisting of a ferrite rod. The high magnetic susceptibility of ferrites makes it possible to construct ferrite-rod antennas that, for identical induced electromotive forces, are much smaller than conventional loop antennas, which have no core.
