Abstract
An antenna module mounted on a vehicle, according to an embodiment, comprises: a PCB on which a transmission line is formed; and an antenna element coupled to the PCB and configured such that metal patterns are interconnected on a surface thereof in a first axial direction and in a second axial direction perpendicular to the first axial direction. The metal patterns comprise: a first branch line arranged such that the metal patterns arranged in the first axis direction have lengths overlapping each other on the second axis; and a second branch line extending from an end of the first branch line connected to the PCB, to a portion parallel to the PCB, so as to be perpendicular to the PCB.
Claims19
An antenna module mounted on a vehicle, the antenna module comprising:
- a printed circuit board (PCB) with transmission lines formed thereon;
- and
- an antenna element coupled to the PCB, and configured such that metal patterns on one surface thereof are interconnected in a first axial direction and a second axial direction perpendicular to the first axial direction,
- wherein the metal patterns comprise:
- a first branch line configured such that metal patterns disposed in the first axial direction have an overlapped length on the second axis;
- a second branch line extending from an end of the first branch line connected to the PCB to a portion parallel to the PCB, to be perpendicular to the PCB, and
- wherein the antenna element on which the first branch line and the second branch line are formed is disposed perpendicular to the PCB, and
- the antenna element is coupled to the PCB to be rotatable relative to the PCB.
A vehicle having an antenna module, the vehicle comprising:
- an antenna module disposed on a bottom of a roof of the vehicle or on glass 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), and a base station,
- the antenna module comprises:
- a printed circuit board (PCB) with transmission lines formed thereon;
- and
- an antenna element coupled to the PCB, and configured such that metal patterns on one surface thereof are interconnected in a first axial direction and a second axial direction perpendicular to the first axial direction,
- wherein the metal patterns comprise:
- a first branch line configured such that metal patterns disposed in the first axial direction have an overlapped length on the second axis;
- and
- a second branch line extending from an end of the first branch line connected with the PCB to a portion parallel to the PCB, to be perpendicular to the PCB, and
- wherein the antenna element on which the first branch line and the second branch line are formed is disposed perpendicular to the PCB, and
- the antenna element is coupled to the PCB to be rotatable relative to the PCB.
