Abstract: This application provides a gap waveguide antenna structure and an electronic device, and relates to the field of communication radars. The antenna structure includes a top layer, a gap waveguide structure, a microstrip structure, and a bottom layer. The top layer is parallel to the bottom layer. A first metal layer and a second metal layer are laid on two sides of a dielectric layer of the top layer, and the microstrip structure is disposed on the second metal layer. A frame of the microstrip structure is separated from metal of the second metal layer by leaving a space. The foregoing special antenna structure can reduce a transmission loss, improve a coupling capability, and effectively improve transmission efficiency of energy or an electromagnetic wave.
