Abstract
The present disclosure relates to a waveguide fed open slot antenna. In some examples, the antenna comprises a waveguide section, a slot, a matching load, a waveguide bottom extension, and a vertical metal wall. The waveguide section can be in the form of a rectangular waveguide or a substrate integrated waveguide (SIW). The slot can comprise a rectangle, with one of its long sides abutting the top surface of the waveguide section, and another long side abutting the matching load, while the two short sides do not connect any metal. The waveguide bottom extension can be rectangular. The end of the waveguide bottom extension and the edge of the matching load on the side close to the open slot can be connected together by the vertical metal wall. In this way, the slot can be excited.
Claims26
An antenna, comprising:
- a waveguide section positioned on a first side of a slot in the antenna;
- a matching load positioned on a second side of the slot in the antenna;
- a waveguide extension that extends a surface of the waveguide section and connects with the matching load, the slot being separate from the waveguide extension;
- and
- a metal wall that connects the waveguide extension and the matching load.
A system, comprising:
- a waveguide section positioned on a first side of a slot in the antenna;
- a matching load positioned on a second side of the slot in the antenna;
- and
- a waveguide extension that extends a surface of the waveguide section and connects with the matching load, the waveguide extension being separate from the slot.
A device, comprising:
- a waveguide section positioned on a first side of a slot in the device;
- a matching load positioned on a second side of the slot;
- a waveguide extension that extends a surface of the waveguide section across the slot and connects with the matching load, the slot being separate from the waveguide extension;
- and
- a metal wall that connects a first side of the waveguide extension that is away from the waveguide section with a first side of the matching load that is located proximal to the slot.
