Abstract

Methods and systems for chip-to-chip communication via on-chip leaky wave antennas are provided. In this regard, RF signals may be communicated between a first leaky wave antenna in a first integrated circuit and a second leaky wave antenna in a second integrated circuit, where the first integrated circuit and the second integrated circuit are housed in a single integrated circuit package. The first integrated circuit and the second integrated circuit may be electrically isolated from one another. One or both of the first leaky wave antenna and the second leaky wave antenna may comprise a pair of coplanar conductive lines. Spacing between the coplanar conductive lines may be configured by applying a voltage which causes one or both of the coplanar conductive lines to deflect towards or away from the other one of the coplanar conductive lines.

Claims (27)

1. A method for communication, the method comprising:

communicating RF signals between a first leaky wave antenna in a first integrated circuit and a second leaky wave antenna in a second integrated circuit, wherein said first integrated circuit and said second integrated circuit are housed in a single integrated circuit package;

adjusting a placement of a feedpoint within one or both of said first leaky wave antenna and said second leaky wave antenna to adjust an impedance of said one or both of said first leaky wave antenna and said second leaky wave antenna;

adjusting a height of a cavity of one or both of said first and second leaky wave antennas to adjust a resonant frequency of said cavity.

2. The method according to claim 1 , wherein said first integrated circuit and said second integrated circuit are electrically isolated from one another.

3. The method according to claim 1 , wherein each of said first integrated circuit and said second integrated circuit is flip-chip-bonded to said single integrated circuit package.

4. The method according to claim 3 , wherein said single integrated circuit package is affixed to a printed circuit board.

5. The method according to claim 1 , comprising controlling a frequency of said RF signals based on an angle between said first leaky wave antenna and said second leaky wave antenna.

6. The method according to claim 1 , wherein one or both of said first leaky wave antenna and said second leaky wave antenna comprises a pair of coplanar conductive lines.

7. The method according to claim 6 , wherein said adjusting said height of said cavity comprises controlling spacing between said coplanar conductive lines by applying a voltage which causes one or both of said coplanar conductive lines to deflect towards or away from the other one of said coplanar conductive lines.

8. The method according to claim 1 , wherein one or both of said first leaky wave antenna and said second leaky wave antenna comprises a microstrip waveguide.

9. The method according to claim 8 , wherein said adjusting said height of said cavity comprises controlling spacing between a conductive strip of said microstrip waveguide and a reference plane of said microstrip waveguide by applying a voltage which causes said conductive strip to deflect towards or away from said reference plane.

10. The method according to claim 1 , wherein one or both of said first integrated circuit and said second integrated circuit comprise one or more additional leaky wave antennas for communicating with devices external to said single integrated circuit package.

11. A system for communication, the system comprising:

one or more circuits and/or processors for use in a device comprising a plurality of integrated circuits housed in a single integrated circuit package, wherein said one or more circuits are operable to:

communicate RF signals between a first leaky wave antenna in a first one of said plurality of integrated circuits and a second leaky wave antenna in a second one of said plurality of integrated circuits;

adjust a placement of a feedpoint within one or both of said first leaky wave antenna and said second leaky wave antenna to adjust an impedance of said one or both of said first leaky wave antenna and said second leaky wave antenna;

adjust a height of a cavity of one or both of said first and second leaky wave antennas to adjust a resonant frequency of said cavity.

12. The system according to claim 11 , wherein said first one and said second one of said plurality of integrated circuits are electrically isolated from one another.

13. The system according to claim 11 , wherein each of said first integrated circuit and said second integrated circuit is flip-chip-bonded to said single integrated circuit package.

14. The system according to claim 13 , wherein said single integrated circuit package is affixed to a printed circuit board.

15. The system according to claim 11 , wherein said one or more circuits and/or processors are operable to control a frequency of said RF signals based on an angle between said first leaky wave antenna and said second leaky wave antenna.

16. The system according to claim 11 , wherein one or both of said first leaky wave antenna and said second leaky wave antenna comprises a pair of coplanar conductive lines.

17. The system according to claim 16 , wherein said one or more circuits and/or processors are operable to adjust said height of said cavity by controlling said spacing between said coplanar conductive lines by applying a voltage which causes one or both of said coplanar conductive lines to deflect towards or away from the other one of said coplanar conductive lines.

18. The system according to claim 11 , wherein one or both of said first leaky wave antenna and said second leaky wave antenna comprises a microstrip waveguide.

19. The system according to claim 18 wherein said one or more circuits and/or processors are operable to adjust said height of said cavity by controlling spacing between a conductive strip of said microstrip waveguide and a reference plane of said microstrip waveguide by applying a voltage which causes said conductive strip to deflect towards or away from said reference plane.

20. The system according to claim 11 , wherein one or both of said first integrated circuit and said second integrated circuit comprise one or more additional leaky wave antennas for communicating with devices external to said single integrated circuit package.
