The design of a resonant slot array antenna in a single layer ridge gap waveguide is presented. Linear and planar array configurations are developed. The linear array includes eight series slots in the ridge gap waveguide that is powered by a coaxial transmission line. The planar antenna array is developed by incorporating a power divider of four branches in the ridge gap waveguide layer. Each branch of the power divider feeds the linear array. The planar antenna detail design for Ku-band is provided, and the manufactured antenna is measured. The antenna impedance bandwidth of 7% at 13.5GHz centre frequency, the gain of 20.5dBi and the side lobe level of <14dB are obtained.
