Electric Field of a Loop Antenna

In radio and telecommunications a dipole antenna or doublet is the simplest and most widely used class of antenna. Large loop antennas or self-resonant loop antennas have a perimeter close to one wavelength at the operating frequency which makes them self.

Antenna Radio Physics And Mathematics Radio Electromagnet

A loop antenna is a radio antenna consisting of a loop or coil of wire tubing or other electrical conductor that is usually fed by a balanced source or feeding a balanced loadWithin this physical description there are two distinct types.

. Named as slot antenna because of its construction which includes a metal plate having many slots or cuts in it. The dipole is any one of a class of antennas producing a radiation pattern approximating that of an elementary electric dipole with a radiating structure supporting a line current so energized that the current has only one node at each end. The applications of slot antennas are in aircraft radars and phased arrays.

The magnetic and electric fields in slot antenna are opposite as in dipole. PCB antennas Basic. The last type of Antenna on the list is the slot antenna.
