Abstract :
We propose a double-layer slotted waveguide array antenna having a wide bandwidth and a high efficiency for 120 GHz band. The diffusion bonding of laminated thin metal plates provides high precision even in very high millimeter bands such as 120 GHz. We design a 16×16-element array antenna having 90% peak aperture efficiency with 33.4 dBi at 126.5 GHz.
