ABSTRACT:
A multi-band microstrip antenna comprising a plurality of separate radiat elements which operate at widely separated frequencies from a single common input point. The common input point is fed at all the desired frequencies from a single transmission feed line. A variety of combinations of microstrip elements can be used. The individual radiating elements are each made to look substantially like an open circuit to all other frequencies but the respective frequency at which they are to operate by respective feed point location and dimensioning of the transmission lines from the common input point to the feed points of the separate elements.
