Abstract
An antenna module mounted on a vehicle is provided. The antenna module includes a PCB having a transmission line formed therein; an antenna PCB coupled to the PCB and having a power supply pattern formed on one surface thereof and a metal pattern formed at at least one of one side and the other side of the power supply pattern; and a filter unit configured to electrically connect the metal pattern to a ground pattern of the PCB in a specific band. The antenna PCB includes a slot radiator configured to radiate a wireless signal through a slot region formed by a first length in a first axis direction inside the metal pattern.
Claims20
An antenna module configured to be mounted on a vehicle, the antenna module comprising:
- a printed circuit board (PCB) having a transmission line disposed thereon;
- an antenna PCB coupled to the PCB, and disposed with a feed pattern on one surface thereof and a metal pattern disposed on at least one of one side and the other side of the feed pattern;
- and
- a filter part configured that electrically connects the metal pattern and a ground pattern of the PCB in a specific band, wherein the antenna PCB comprises:
- a slot radiator configured to radiate a wireless signal through a slot region disposed to have a first length in a first axis direction inside the metal pattern;
- and
- a second radiator connected to an end portion of the feed pattern, and disposed in an upper region of the metal pattern in a second axis direction.
A vehicle having an antenna module, the vehicle comprising:
- an antenna module disposed below a roof of the vehicle;
- and
- a processor disposed inside or outside the antenna module, and configured to communicate with at least one of an adjacent vehicle, a road side unit (RSU), or a base station;
- wherein the antenna module further comprises:
- a printed circuit board (PCB) having a transmission line disposed thereon;
- a bottom cover having the PCB disposed therein, the bottom cover configured to be attached to the vehicle;
- an antenna PCB coupled to the PCB, and disposed with a feed pattern on one surface thereof and a metal pattern disposed on at least one of one side and the other side of the feed pattern;
- and
- a filter part configured to electrically connect the metal pattern and a ground pattern of the PCB in a specific band,
- wherein the antenna PCB comprises:
- a slot radiator configured to radiate a wireless signal through a slot region disposed to have a first length in a first axis direction inside the metal pattern;
- and
- a second radiator connected to an end portion of the feed pattern, and disposed in an upper region of the metal pattern in a second axis direction.
