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.
Claims26
An antenna assembly comprising:
- a plurality of antenna elements including:
- a UHF antenna element configured for receiving UHF high definition television signals from about 470 megahertz to about 698 megahertz;
- a VHF antenna element is configured to be operable for receiving VHF high definition television signals from about 174 megahertz to about 216 megahertz;
- wherein the UHF antenna element and the VHF antenna element are parasitically coupled without a direct ohmic connection between the UHF antenna element and the VHF antenna element, whereby the antenna assembly is configured to be operable for receiving VHF and UHF high definition television signals without using a diplexer and a VHF balun;
- and
- wherein the VHF antenna element comprises a curved portion having a curvature substantially matching a curvature of a curved portion of the UHF antenna element that overlaps in front or in back of the curved portion of the VHF antenna element and that is alongside the curved portion of the VHF antenna element.
An antenna assembly comprising:
- a plurality of antenna elements including:
- a UHF antenna element configured for receiving UHF high definition television signals from about 470 megahertz to about 698 megahertz;
- a VHF antenna element is configured to be operable for receiving VHF high definition television signals from about 174 megahertz to about 216 megahertz;
- wherein the UHF antenna element and the VHF antenna element are parasitically coupled without a direct ohmic connection between the UHF antenna element and the VHF antenna element, whereby the antenna assembly is configured to be operable for receiving VHF and UHF high definition television signals without using a diplexer and a VHF balun;
- and
- wherein a plane including the VHF antenna element is spaced apart from and separated in the z-direction from a plane including the UHF antenna element, such that the VHF antenna element is not coplanar with the UHF antenna element.
