Host-independent VHF-UHF active antenna system
First Claim
1. An antenna system for use with a media device, the antenna system comprising:
- a multi-mode active antenna configurable to operate in a plurality of modes associated with a UHF band or a VHF band, each mode of the plurality of modes having a distinct radiation pattern;
a supplemental tuner, the supplemental tuner being separate from a primary tuner associated with the media device;
a switching device movable between at least two positions, the multi-mode active antenna coupled to the supplemental tuner when the switching device is in a first position, the multi-mode active antenna coupled to the media device when the switching device is in a second position; and
one or more controllers configured to;
obtain one or more metrics while the switching device is in the first position, the one or more metrics indicative of performance of the active antenna in each of the plurality of modes;
determine a selected mode of operation for the active antenna based, at least in part, on the one or more metrics; and
configure the active antenna to operate in the selected mode.

Abstract
An antenna system for use with a media device is provided. The antenna system includes a multi-mode active antenna configurable to operate in a plurality of modes. Each mode of the plurality of has a distinct radiation pattern. The antenna system includes a supplemental tuner that is separate from a primary tuner associated with the media device. The antenna system includes a switching device movable between at least two positions to selectively couple the active antenna to the supplemental tuner. When the switching device is in a first position, the active antenna is coupled to the supplemental tuner. When the switching device is in a second position, the active antenna is coupled to the media device.

13. A method of configuring an antenna system for use with a media device, the antenna system comprising a multi-mode active antenna, a switching device, and a supplemental tuner that is separate from a primary tuner associated with the media device, the method comprising:
-
coupling the active antenna to the supplemental tuner via the switching device; obtaining, by one or more controllers of the antenna system, one or more metrics while the active antenna is coupled to the supplemental tuner, the one or more metrics indicative of performance of the active antenna in each of a plurality of modes associated with a UHF band or a VHF band, wherein each mode of the plurality of modes has a distinct radiation pattern; determining, by the one or more controllers, a selected operating mode for the active antenna based, at least in part, on the one or more metrics; and configuring, by the one or more controllers, the active antenna to operate in the selected operating mode. - View Dependent Claims (14, 15, 16, 17, 18)

19. An active antenna operable in a plurality of modes, each mode of the plurality of modes having a distinct radiation pattern, the active antenna comprising:
-
a substrate; a first antenna positioned on the substrate adjacent to a ground plane, the first antenna configured for multiple resonances in a UHF band or a VHF band; a first parasitic element positioned adjacent to the first antenna; a first switch coupled between the first parasitic element and the ground plane, the first switch configured to open-circuit, short-circuit, or reactively load the first parasitic element; a second antenna positioned on the substrate adjacent to the ground plane, the second antenna configured for multiple resonances in the UHF band or the VHF band; a second parasitic element positioned adjacent to the second antenna; and a second switch coupled between the second parasitic element and the ground plane, the second switch configured to open-circuit, short-circuit, or reactively load the second parasitic element; and wherein an arm of the first antenna is connected to an arm of the second antenna.
