Antenna structure and communication device

An antenna structure, comprising:

• a feeding structure;
• and
• a leaky-wave antenna, wherein
• the leaky-wave antenna comprises a rectangular waveguide and a radiating element, and the radiating element is located on any side wall of the rectangular waveguide;
• the radiating element comprises slot elements, and a plurality of groups of slot elements are arranged at intervals in an extension direction of the rectangular waveguide;
• the slot element comprises a first slot and a second slot, the first slot and the second slot are arranged with an included angle, and the first slot and the second slot are arranged at intervals in the extension direction of the rectangular waveguide;
• the leaky-wave antenna further comprises a control component, the control component is connected to the radiating element, and the control component is configured to control the first slot and the second slot to be open-circuited or short-circuited;
• and
• the feeding structure is arranged at an end of the rectangular waveguide, and the feeding structure is configured to feed electromagnetic signals in two mutually orthogonal modes into the rectangular waveguide.
