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.

A radio-frequency device comprises a printed circuit board and a radio-frequency package, which is mounted on the printed circuit board at a first mounting point and has a radio-frequency chip and a radio-frequency radiation element, wherein the printed circuit board has a first elasticity at least in a first section comprising the first mounting point.

Embodiments relate to machines including a movable part. A transmitter circuit is configured to generate a radio signal and to transmit the radio signal towards the movable part via a transmit waveguide. A reflection of the radio signal from the movable part is received by a receive waveguide and guided through the receive waveguide to a receiver circuit, which is configured to determine a position and/or a speed of the movable part based on at least the received radio signal. The transmitter circuit and the receiver circuit may be comprised by a radar sensor.
