Abstract: An antenna device and a vehicle including the same, includes at least one antenna disposed on a transparent inclined surface in an interior of a vehicle, and including a radiation patch facing a first radiation direction being perpendicular to the inclined surface, and a partition wall surrounding at a portion of the at least one antenna. The partition wall is configured so that a beam radiated from the radiation patch in the first radiation direction is inclined from the first radiation direction toward a second radiation direction.

Abstract: A built-in antenna includes a first printed circuit board (PCB) having antenna areas arranged so that at least one antenna area is arranged at each of the corners of the first PCB. The antenna areas are spaced apart from one another, and circuit components are arranged in areas other than the antenna areas. A second PCB has first antenna patterns respectively arranged at locations corresponding to the antenna areas on the first PCB. A third PCB is vertically coupled to the first and second PCBs to electrically connect them. The second PCB includes a second antenna pattern arranged in an area other than areas in which the first antenna patterns are arranged. This increases a degree of freedom in design and improves bandwidth and efficiency by arranging each antenna in a plate-shaped structure.

Abstract: Disclosed is a patch antenna, which is formed so that the upper surface of a dielectric layer has a wider area than the lower surface thereof and is mounted on a printed circuit board to form an air gap, thus maximizing antenna performance while implementing lightweight. The disclosed patch antenna includes a dielectric layer, a radiation patch formed on the upper surface of the dielectric layer, and a lower patch formed on the lower surface of the dielectric layer; and the dielectric layer is formed so that an area of the upper surface is wider than an area of the lower surface to form an air gap between the printed circuit board and the dielectric layer.

Abstract: A printed circuit board (PCB) is disposed to stand vertically on a main board and having a first surface and a second surface opposite to the first surface. A main antenna pattern is formed on the first surface of the PCB to operate in dual band including a low frequency band and a high frequency band. A bandwidth extension pattern is formed on the second surface of the PCB and formed to operate in the high frequency band, the bandwidth extension pattern having a coupling stub which forms an overlapping portion with a portion of the main antenna pattern, with the PCB interposed therebetween, to implement an antenna having an extended bandwidth, which operates together with the portion of the main antenna pattern in the high frequency band.

Abstract: A circularly polarized ceramic patch antenna having an extended ground for a vehicle is provided. The extended ground is formed under a patch antenna, has a predetermined thickness, is formed of a metal conductor having the same shape as the patch antenna, and is electrically connected to a ground plane formed on a board. The thickness of the extended ground is adjusted, so that it is possible to adjust radiation efficiency of the ceramic patch antenna that operates at a specific frequency band. Thus, the ceramic patch antenna has the effect of improving directionality of a radiation pattern formed in a direction parallel to the ground plane, and the effect of reducing a null point caused by a field effect to increase an antenna gain thereof.
