Abstract

An antenna system and method for managing identification, location, direction and communication with nearby wireless communication devices is provided. Various embodiments can be implemented to enhance the performance of advertising systems, location services, military systems, and social gaming.

Claims

1. A multi-mode antenna system configured to enable one or more social networking capabilities between a designated device and one or more linkable devices each connected within a wireless network, the antenna system comprising:

a modal antenna coupled to an antenna tuning module for configuring the modal antenna in one of a plurality of possible antenna modes, wherein the modal antenna is configured to produce a distinct radiation pattern when configured in each of the plurality of possible antenna modes; and

an adaptive processor coupled to each of the modal antenna and the antenna tuning module, the adaptive processor being configured with an algorithm for adjusting a radiation pattern associated with the modal antenna, the algorithm configured to;

identify the one or more linkable devices within the wireless network, said linkable devices being within a user-defined proximity with the designated device containing the multi-mode antenna system; and

send control signals to the antenna tuning module for adjusting the radiation pattern of the modal antenna;

wherein the multi-mode antenna system is configured to;

selectively produce one of;

a gain maxima or a null in a direction associated with each of the identified linkable devices.

2. The antenna system of claim 1, wherein the modal antenna comprises:

an antenna radiator disposed above a ground plane forming an antenna volume therebetween, a first parasitic element at least partially disposed within said antenna volume, said first parasitic element being coupled with a first active tuning element for varying a reactance of the antenna; and

a second parasitic element positioned outside of the antenna volume and adjacent to the antenna radiator, said second parasitic element being coupled with a second active tuning element for varying a current mode thereon.

3. The antenna system of claim 1, wherein the antenna system is configured to:

communicate with each of the linkable devices;

obtain a device identification tag from each of the linkable devices; and

process each of the identification tags to determine for each linkable device whether to link or to block communications therewith.

4. The antenna system of claim 3, wherein the antenna system is further configured to:

compare each of the identification tags with a lookup table to identify a user-specified instruction for each device, wherein the instruction comprises one of;

connect or block; and

implement the user specified instruction by adjusting the radiation pattern of the modal antenna.

5. The antenna system of claim 1, comprising:

two or more modal antennas configured in an array.

6. The antenna system of claim 5, wherein the antenna system is configured to adjust the radiation pattern of each of the modal antennas to adjust the overall radiation pattern of the array.

7. In a designated device comprising a multi-mode antenna system as described in claim 1, a method for enabling one or more social networking capabilities between the designated device and another device within a wireless network, the method comprising:

identifying one or more linkable devices located within proximity to the designated wireless device; and

at least one of;

optimizing a communication link between the designated device and one or more of the linkable devices in the network;

terminating communication between the designated device and one or more of the linkable devices;

adjusting transmit power of one or more of the designated device and linkable devices for improving communication therebetween;

categorizing one or more of the linkable devices into one or more user-defined groups;

transmitting a data file to one or more of the linkable devices based on group assignment or proximity within the network;

or

providing communication with one or more linkable devices determined to be present within a pre-determined proximity with the designated device.

8. The method of claim 7, wherein said optimizing comprises forming gain maxima in the radiation pattern by selecting an optimum antenna mode of the modal antenna.

9. The method of claim 7, wherein said optimizing comprises steering the antenna radiation pattern of the designated device to maximize link quality in a direction of one or more of the linkable devices.

10. The method of claim 7, wherein said terminating comprises creating a null in the antenna radiation pattern and orienting said null in a direction of one or more of the linkable devices.

11. The method of claim 7, wherein said terminating comprises reducing antenna transmit power in a direction of one or more of the linkable devices.

12. The method of claim 7, wherein said terminating comprises steering the null in a direction of one or more of the linkable devices.

13. The method of claim 7, further comprising:

communicating data to one or more of the linkable devices, wherein said data comprises instructions for configuring a mode of a modal antenna associated with the linkable device.
