Abstract :
A planar waveguide array with single layer /spl pi/-junctions has been designed at 60 GHz. Excellent efficiency of more than 55% and the gain of 35 dBi were measured. For realizing the ideal efficiency of 90% in principle, the critical point in the fabrication of this antenna is the bonding between two elements, that is the slotted plate and the grooved feeding structure. Accurate alignment and perfect electrical contact is required.
