Abstract : The patent describes an antenna capable of 180 degrees scan with improved gain characteristics at end-fire realized by combining multiple element array and surface wave antenna structures. An end-fire feed element is positioned to radiate along a column array of antenna elements. A transmitter is switched to feed either the end-fire feed elements or the column array of antenna elements and the column array antenna elements are short circuited during end-fire operation.
