Loop Antenna Catalog

loopCircular	loopRectangular	Antenna Element Catalog

Loop antennas are conductors bent into the shape of a circle or a rectangle with a gap in between for terminals. Loops can be electrically small or electrically large. Electrically small loops are used in receiving mode where the signal-to-noise ratio is more important than antenna efficiency. Electrically large loops are used in directional arrays such as Yagi Uda arrays, quad arrays.
