ABSTRACT:
A high frequency applicator for energizing electrodeless lamps is described. The applicators are made of two loops of wire electrically attached to the ends of phased feed points of a planar transmission line. The loops are face each other and are positioned so as to form a gap in which a lamp capsule is placed. Each loop is made of three partial turns, the first and second turns being parallel to each other, each partial turn having a first and second end and the third partial turn is attached to the second end of each partial turn and positioned orthogonal the first and second turns. The plane formed by the third turn makes a dihedral angle between 9.degree. and 135.degree. with the planar transmission line.
