Abstract: The antenna feed includes a waveguide radiator with a conductive flange positioned about the waveguide near its radiating end. The flange includes one or more corrugations which each have tapered walls and which is truncated at its root and crest by a flat or curved plane. The corrugations thus may have a trapezoidal cross-section or a curved root and crest cross-section. The curvature may be sinusoidal.

Abstract: The antenna feed includes a waveguide radiator with a conductive flange positioned about the waveguide near its radiating end. A dielectric element is positioned about the waveguide between the flange and the radiating end and establishes the dielectric surface impedance seen by the waveguide. The dielectric element may consist of one or more layers of dielectric material to form a composite dielectric. One of the layers may be an air gap adjacent to the flange. The size and position of the flange and dielectric element will control the radiation pattern of the beam from the feed.

Abstract: A doll which is adapted to simulate kissing by leaving a lip imprint of marking material on objects contacted therewith is disclosed. The head of the doll is provided with an inwardly directed cavity in the oral region thereof which in turn is adapted to receive a pad of porous material in which the marking material is impregnated. The end of the pad is provided with a lip shaped extension adapted to project outwardly from the face of the doll so that when the doll's face is impressed against an object, an imprint of marking material in the shape of the lips is produced. In one form of the invention the pad is received in a closed cavity and in an alternate form of the invention the pad is mounted at the forward end of a pushing member slidably mounted in the doll's head so that a more positive "kiss" imprint may be made.
