Abstract :
The Yagi concept is introduced for the planar microstrip array. With parasitic director and reflector patches located on the same plane of the driven element, the beam peak, by the effect of mutual coupling, can be tilted toward the endfire direction. With this capability, the power divider and phase delay transmission lines in a conventional array are no longer needed, and hence the array efficiency is increased. Both linear and circular polarization microstrip Yagi arrays are described.<>
