A radar module comprising:
- a substrate;
- a communication device disposed on the substrate;
- an antenna unit disposed on the substrate;
- and
- a connection line disposed on the substrate and connecting the communication device and the antenna unit, and including at least one stub,
- wherein the antenna unit includes a transmitting antenna unit and a receiving antenna unit,
- wherein each of the transmitting antenna unit and the receiving antenna unit includes:
- a radiator including a feeding slot;
- and
- a feeding line connecting the connection line and the radiator,
- wherein a direction of a beam radiated from at least one of the transmitting antenna unit and the receiving antenna unit is adjusted by controlling a first variable related to the feeding slot and a second variable related to the stub, and
- wherein at least one of the first variable and the second variable in the transmitting antenna unit is same as at least one of the first variable and the second variable in the receiving antenna unit.
A radar device comprising:
- a radar module adapted to sense movement of an object in a vehicle;
- and
- a control unit adapted to detect the movement of the object in the vehicle using a reception signal acquired through the radar module, and output a movement sensing signal of the object when the movement of the object is sensed,
- wherein the control unit is adapted to output the movement sensing signal to at least one of a pre-registered terminal and an electronic control unit of the vehicle based on whether the sensed object is moving,
- wherein the radar module includes:
- a communication device disposed on the substrate;
- an antenna unit disposed on the substrate;
- and
- a connection line disposed on the substrate and connecting between the communication device and the antenna unit, and including at least one stub,
- wherein the antenna unit includes a transmitting antenna unit and a receiving antenna unit,
- wherein each of the transmitting antenna unit and the receiving antenna unit includes:
- a radiator including a feeding slot;
- and
- a feeding line connecting between the connection line and the radiator,
- wherein the stub includes a first stub arranged on one side of the connection line;
- and
- a second stub arranged on other side of the connection line opposite to the one side,
- wherein a first variable including a length of the feeding line and a width of the feeding line and a second variable including a length of the first stub, a length of the second stub, and a spacing between the first stub and the second stub are adjusted in order to adjust a direction of a beam radiated from at least one of the transmitting antenna unit and the receiving antenna unit, and
- wherein at least one of the first variable and the second variable in the transmitting antenna unit is same as at least one of the first variable and the second variable in the receiving antenna unit.
