Abstract

A method for configuring a multi-mode antenna system is provided. The method includes obtaining channel selection data indicating the antenna system is tuned to a first channel of a plurality of channels. The method includes configuring the antenna system in at least one operating mode of a plurality of operating modes, with each operating mode of the plurality of operating modes having a distinct radiation pattern. The method includes obtaining data indicative of a channel quality indicator for the at least one operating mode. The method includes determining a selected operating mode for the multi-mode antenna system for the first channel of the plurality of channels based, at least in part, on the data indicative of the channel quality indicator. The method includes configuring the antenna system in the selected operating mode when the multi-mode antenna system is tuned to the first channel.

First claim

What is claimed is:

1. A method of configuring a multi-mode antenna communicatively coupled to a device, the method comprising:
configuring, by one or more processors, the multi-mode antenna in each of a plurality of operating modes while the device is tuned to a first channel of a plurality of channels, the multi-mode antenna having a different radiation pattern in each of the plurality of operating modes;
obtaining, by the one or more processors, data indicative of a channel quality indicator for each of the plurality of operating modes while the device is tuned to the first channel;
determining, by the one or more processors, a score for each of the plurality of operating modes based, at least in part, on the data indicative of the channel quality indicator;
wherein determining the score for each of the plurality of operating modes comprises determining, by the one or more processors, the score for each of the plurality of operating modes based, at least in part, on the data and a first weighted value assigned to the first channel of the plurality of channels, the first weighted value being different than a second weighted value assigned to a second channel of the plurality of channels;

determining, by the one or more processors, one of the plurality of operating modes as a selected operating mode for the multi-mode antenna for the first channel based, at least in part, on the data; and
configuring, by the one or more processors, the multi-mode antenna in the selected operating mode for the multi-mode antenna for the first channel.

2. The method of claim 1 , wherein determining one of the plurality of operating modes as the selected operating mode for the multi-mode antenna for the first channel comprises determining, by the one or more processors, the selected operating mode based, at least in part, on the score determined for each of the plurality of operating modes.

3. The method of claim 1 , further comprising:
configuring, by the one or more processors, the multi-mode antenna in each of the plurality of operating modes in response to device changing from being tuned to the first channel of the plurality of channels to being tuned to a second channel of the plurality of channels.

4. The method of claim 3 , further comprising:
obtaining, by the one or more processors, data indicative of a channel quality indicator for each of the plurality of operating modes while the device is tuned to the second channel;
determining, by the one or more processors, one of the plurality of operating modes as a selected operating mode for the multi-mode antenna for the second channel based, at least in part, on the data indicative of the channel quality indicator for each of the plurality of operating modes while the device is tuned to the second channel; and
configuring, by the one or more processors, the multi-mode antenna in the selected operating mode for the multi-mode antenna for the second channel.

5. The method of claim 4 , wherein the selected operating mode for the multi-mode antenna for the second channel is different than the selected operating mode for the multi-mode antenna for the first channel.

6. The method of claim 1 , wherein the data indicative of the channel quality indicator comprises at least one of a signal to noise ratio (SNR), a signal-to-interference-plus-noise ratio (SINR), a magnitude error ratio (MER), an error vector magnitude (EVM), a bit error rate (BER), a block error rate (BLER), and a packet error rate (PER).

7. The method of claim 1 , wherein the device comprises a media device.

8. A multi-mode antenna system comprising:
a multi-mode antenna configurable in a plurality of operating modes, each of the plural of operating modes having a distinct radiation pattern; and
one or more processors configured to perform operations, the operations comprising:
configuring the multi-mode antenna in each of the plurality of operating modes while a device communicatively coupled to the multi-mode antenna is tuned to a first channel of a plurality of channels;
obtaining data indicative of a channel quality indicator for each of the plurality of operating modes while the device is tuned to the first channel;
determining a score for each of the plurality of operating modes based, at least in part, on the data indicative of the channel quality indicator;
wherein determining the score for each of the plurality of operating modes comprises determining the score for each of the plurality of operating modes based, at least in part, on the data and a first weighted value assigned to the first channel of the plurality of channels, the first weighted value being different than a second weighted value assigned to a second channel of the plurality of channels;

determining one of the plurality of operating modes as a selected operating mode for the multi-mode antenna for the first channel based, at least in part, on the data; and
configuring the multi-mode antenna in the selected operating mode for the multi-mode antenna for the first channel.

9. The multi-mode antenna system of claim 8 , wherein the multi-mode antenna comprises a driven element and a parasitic element.

10. The multi-mode antenna system of claim 8 , wherein the operations further comprise:
configuring the multi-mode antenna in each of the plurality of operating modes in response to device changing from being tuned to the first channel of the plurality of channels to being tuned to a second channel of the plurality of channels.

11. The multi-mode antenna system of claim 8 , wherein the operations further comprise:
configuring the multi-mode antenna in each of the plurality of operating modes after a predetermined amount of time has lapsed since configuring the multi-mode antenna in the selected operating mode.
