Abstract :
This paper presents novel single-layer waveguides for challenging design of high-gain, high-efficiency, and mass-producible planar slotted arrays for the millimeter wave region. The key features of three types of waveguides, as well as state-of-the-art performance of the arrays using these, are surveyed. A model antenna realizes 35-dBi gain and 64% efficiency at 60.2 GHz
