Abstract
A radar device is disclosed. The radar device may include a circuit board on which a circuit element that generates or receives electromagnetic waves is placed; a waveguide antenna stacked on one surface of the circuit board, and in which a port through which the electromagnetic waves pass is through-formed; and a plurality of pins spaced apart from each other, in the form of surrounding an opening of the port, on one surface of the waveguide antenna facing the circuit board, and having a pillar shape.
Claims19
A radar device, comprising:
- a circuit board on which a circuit element that generates or receives electromagnetic waves is placed;
- a waveguide antenna stacked on one surface of the circuit board, and in which a port through which the electromagnetic waves pass is through-formed;
- and
- a plurality of pins spaced apart from each other, in the form of surrounding an opening of the port, on one surface of the waveguide antenna facing the circuit board, and having a pillar shape.
A radar device that generates and transmits electromagnetic waves and receive electromagnetic waves that are reflected and returned from the outside, the radar device comprising:
- a plate-shaped first waveguide in which a first port through which the electromagnetic waves pass is through-formed;
- a second waveguide that is stacked on one surface of the first waveguide, and in which a second port through which the electromagnetic waves pass is through-formed, the second port being in communication with the first port;
- and
- a plurality of pins having a polygonal pillar shape, the plurality of pins being disposed to be spaced apart from each other, in a form surrounding an opening of the first port, on one surface of the first waveguide facing the second waveguide, or disposed to be spaced apart from each other, in a form surrounding an opening of the second port, on one surface of the second waveguide facing the first waveguide.
