Abstract

A method and system for point-to-point wireless communications utilizing leaky wave antennas is provided. In this regard, a first device may transmit a RF signal via a leaky wave antenna, and may determine an angle between the leaky wave antenna of the first device and a leaky wave antenna of a second device by adjusting a frequency of the RF signal until a response is received from the second device. The first device may be configured based on the determined angle. A wireless connection may be established between the leaky wave antenna of the first device and the leaky wave antenna of the second device based on the configuration. The first device may generate a notification when the angle is beyond a threshold. The wireless connection may adhere to wireless USB protocols and/or Bluetooth protocols, for example. The second device may generate the response after receiving sufficient energy from the RF signal.

Claims (38)

1. A method for communication, the method comprising:

in a first device comprising a first leaky wave antenna:

transmitting a discovery signal at a frequency that corresponds to a transmission angle;

adjusting said frequency of said discovery signal to change said transmission angle;

receiving a radio frequency (RF) signal via said first leaky wave antenna, wherein said RF signal is received from a second leaky wave antenna of a second device;

determining an angle between said first leaky wave antenna and said second leaky wave antenna based on a received signal strength of said RF signal;

pairing with said second device to establish a communication protocol connection between said first device and said second device when said determined angle is approximately equal to a particular angle; and

preventing pairing with said second device to prevent establishment of a communication protocol connection between said first device and said second device when said determined angle is not approximately equal to said particular angle,

wherein said second device powers up in response to receiving energy exceeding a threshold from said discovery signal.

2. The method according to claim 1 , wherein said leaky wave antenna of said first device is integrated within and/or on an integrated circuit.

3. The method according to claim 1 , wherein said leaky wave antenna of said first device is integrated within and/or on an integrated circuit package.

4. The method according to claim 3 , comprising generating a notification when said particular angle is beyond a threshold.

5. The method according to claim 1 , wherein one or more filters of said first device are configured based on said particular angle.

6. The method according to claim 1 , wherein said second device configures one or more filters based on said received signal strength of said RF signal.

7. A system for communication, the system comprising:

one or more circuits in a first device, said one or more circuits comprising a first leaky wave antenna, and said one or more circuits configured to:

transmit a discovery signal at a frequency that corresponds to a transmission angle;

adjust said frequency of said discovery signal to change said transmission angle;

receive a radio frequency (RF) signal via said first leaky wave antenna, wherein said RF signal is received from a second leaky wave antenna of a second device;

determine an angle between said first leaky wave antenna and said second leaky wave antenna based on a received signal strength of said RF signal;

pair with said second device to establish a communication protocol connection between said first device and said second device when said determined angle is approximately equal to a particular angle; and

prevent pairing with said second device to prevent establishment of a communication protocol connection between said first device and said second device when said determined angle is not approximately equal to said particular angle;

one or more additional circuits in said second device and configured to power up said second device in response to receiving energy exceeding a threshold from said discovery signal.

8. The system according to claim 7 , wherein said leaky wave antenna of said first device is integrated within and/or on an integrated circuit.

9. The system according to claim 7 , wherein said leaky wave antenna of said first device is integrated within and/or on an integrated circuit package.

10. The system according to claim 7 , wherein said one or more circuits are operable to generate a notification when said particular angle is beyond a threshold.

11. The system according to claim 7 , wherein one or more filters of said first device are configured based on said particular angle.

12. The system according to claim 7 , wherein said second device configures one or more filters based on said received signal strength of said RF signal.

13. A communication device, the communication device comprising:

a processor configured to:

transmit a discovery signal at a frequency that corresponds to a transmission angle;

adjust said frequency of said discovery signal to change said transmission angle;

receive a response signal from a second device;

determine an angle between the communication device and a communication partner based on a received signal strength of the response signal;

establish a communication protocol connection between the communication device and the communication partner if the determined angle is less than a threshold; and

prevent a communication protocol connection between the communication device and the communication partner if the determined angle is greater than a threshold,

wherein said discovery signal causes second device to power up in response to energy from said discovery signal exceeding a threshold.

14. The communication device of claim 13 , wherein the processor is configured to stop changing the frequency of the transmitted discovery signal when a maximum transmission angle is reached prior to receiving the response signal from the communication partner.
