Abstract
Exemplary embodiments are disclosed of antenna assemblies configured for reception of television signals, such as high definition television (HDTV) signals. In an exemplary embodiment, an antenna assembly generally includes a VHF antenna element and a UHF antenna element. The VHF antenna element and the UHF antenna element may be parasitically coupled without a direct ohmic connection between the VHF antenna element and the UHF antenna element. The antenna assembly may be configured to be operable for receiving VHF and UHF high definition television signals without using a diplexer and a VHF balun.
Claims46
An antenna assembly configured to be operable for receiving at least VHF and UHF high definition television signals, the antenna assembly comprising:
- a first antenna element;
- and
- a second antenna element;
- wherein the second antenna element comprises a curved portion having a curvature substantially matching a curvature of a curved portion of the first antenna element that overlaps in front or in back of the curved portion of the second antenna element and that is alongside the curved portion of the second antenna element;
- and
- wherein:
- the antenna assembly further comprises a printed circuit board having one or more fastener holes;
- the first antenna element includes one or more fastener holes;
- and
- the printed circuit board is attached to the first antenna element by one or more mechanical fasteners inserted through the one or more fastener holes of the printed circuit board that are aligned with the one or more fastener holes of the first antenna element.
