Abstract :
94 GHz nonresonant shunt and series slot waveguide arrays have been fabricated by using high-resolution photolithographic and chemical etching techniques. The antenna pattern, efficiency and input reflection coefficient for the two types of arrays have been measured and are in good agreement with design predictions.
