Abstract :
The directivity of an elliptic loop antenna having a given perimeter and made of a conducting wire of a given radius is maximised with respect to the minor-axis/major-axis ratio, ¿. It is found that a circular loop does not yield a maximum directivity and that the value of ¿ at which maximum directivity occurs depends on the perimeter.
