What is a loop antenna?

Loop antenna. Part of a series on. Antennas. A loop antenna is a radio antenna consisting of a loop or coil of wire, tubing, or other electrical conductor usually fed by a balanced source or feeding a balanced load.

Does a loop antenna work?

The currents through this loop antenna will be in phase. The magnetic field will be perpendicular to the whole loop carrying the current. The frequency range of operation of loop antenna is around 300MHz to 3GHz . This antenna works in UHF range. A loop antenna is a coil carrying radio frequency current.

What is a small transmitting loop or magnetic loop?

A small transmitting loop antenna, also known as a magnetic loop, with a circumference 10% of a wavelength or less, will have a relatively constant current distribution along the conductor, and the main lobe will be in the plane of the loop.

What is magnetic loop?

The magnetic loop is small, reasonably efficient even close to the ground, has a low take off angle and it has a deep null on each side which lets you null out interference. The antenna also displays directivity characteristics similar to that of a dipole when mounted vertically.
