Transmitting loop antenna for efficiency enhancement

Abstract EN

The single-turn loop antenna is a metallic conductor bent into the shape of a closed curve, such as a circle or a square, with a gap in the conductor to form the terminals.

A multi-turn loop or coil is a series connection of overlaying turns.

The loop is one of the primary antenna structures; its use as a receiving antenna dates back to the early experiments of Hertz on the propagation of electromagnetic waves.

It is poor antenna in transmission, so to use such an antenna; it must enhance to get butter performance in power (gain), bandwidth and efficiency.

Here, some ways that makes this antenna suitable for transmission by changing the cross-section diameter and the structure of material that made.
