Abstract
An embedded surface wave antenna is described of compact design capable of broadband performance both for impedance match and for radiation pattern characteristics comprising two spaced apart conductive planar elements, one element being a transition from a narrow portion to a wider portion according to a continuous function, said one element having an upward inclination away from the other of said conductive planar elements and ending in a termination at the wider portion, a tapered lens material having a downward inclination from said termination toward said other of said conductive planar elements to define a sloping surface therebetween for launching and receiving electromagnetic waves. The subject surface wave antenna may be readily adapted into assemblies of radiating elements in a predetermined electrical and geometric configuration to provide an array rendering a preferred radiation pattern.
