Abstract:
A reconfigurable antenna is disclosed that includes a ground plane, an electrically-conductive microstrip patch element, and a plurality of switches. The patch element is spaced-apart from the ground plane with a dielectric medium between the patch element and the ground plane. The switches are coupled between the ground plane and the patch element. The switches are openable and closable, for example, in response to a control signal from an external television device to configure the state of the reconfigurable antenna. Additional reconfigurable antenna elements are disclosed. Antenna arrays including reconfigurable antenna elements, switchable fixed elements, or a combination thereof are also disclosed.

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.
Abstract:
According to various aspects, exemplary embodiments are provided of antenna assemblies. In an exemplary embodiment, an antenna assembly generally includes at least one antenna element configured to be operable for receiving high definition television signals.

According to various aspects, exemplary embodiments are provided of antenna assemblies. In an exemplary embodiment, an antenna assembly generally includes at least one antenna element configured to be operable for receiving high definition television signals. The antenna assembly may also include at least one reflector spaced-apart from the antenna element that is configured to be operable for reflecting electromagnetic waves generally towards the antenna element.
Abstract:
According to various aspects, exemplary embodiments are provided of bow tie antennas and antenna assemblies that include the same. In an exemplary embodiment, a bow tie antenna includes a pair of antenna elements. Each antenna element includes spaced apart end portions defining an open portion such that the antenna element has an open shape. The open shape is closed by dielectric material disposed between the spaced apart end portions and extending across a gap separating the spaced apart end portions, whereby the dielectric material and pair of antenna elements cooperatively define a closed bow tie shape for the bow tie antenna.
