Abstract

An antenna for directional electronic communication and a directional communication system are provided. In one embodiment, the antenna includes: (1) a protective shell, (2) a Luneberg lens located within the protective shell and (3) multiple radio frequency signal conveyors located proximate a portion of the Luneberg lens and configured with the Luneberg lens to transmit radio frequency signals within a defined region or receive radio frequency signals that originate within the defined region.

Claims

1. A weapon, comprising:

a gun barrel or an aiming device; and

an antenna mounted in alignment with said gun barrel or said aiming device, said antenna including;

a protective shell,

a Luneberg lens located within said protective shell, and

multiple radio frequency signal conveyors located proximate a portion of said Luneberg lens and configured with said Luneberg lens to transmit radio frequency signals within a defined region or receive radio frequency signals that originate within said defined region.

2. The weapon as recited in claim 1 wherein said multiple radio frequency signal conveyors are configured with said Luneberg lens to transmit radio frequency signals within said defined region and receive radio frequency signals that originate within said defined region.

3. The weapon as recited in claim 2 wherein said multiple radio frequency signal conveyors are configured with said Luneberg lens to exclude transmit radio frequency signals to receivers outside said defined region and receive radio frequency signals that originate outside of said defined region.

4. The weapon as recited in claim 1 wherein said defined region is a beam defined by said multiple radio frequency conveyors and said Luneberg lens.

5. The weapon as recited in claim 1 wherein said antenna transmits a radar pulse within said defined region.

6. The weapon as recited in claim 1 wherein said Luneberg lens is configured to collimate diverging radio frequency signals from said radio frequency signal conveyors for transmission within said defined region and cause substantially collimated radio frequencies signals received from said defined region to converge on said radio frequency signal conveyors.

7. The weapon as recited in claim 1 wherein said antenna transmits an interrogation signal within said defined region.

8. The weapon as recited in claim 1 wherein said antenna is mounted in parallel with said gun barrel or said aiming device, wherein said gun barrel or said aiming device are employed to direct operation of said weapon at a target.

9. The weapon as recited in claim 1 further comprising a base station including encryption/decryption circuitry coupled to said antenna.

10. A directional antenna system for directional electronic communication, comprising:

an aiming device; and

an antenna mounted in alignment with said aiming device, said antenna including;

a protective shell,

a Luneberg lens located within said protective shell, and

multiple radio frequency signal conveyors located proximate a portion of said Luneberg lens and configured with said Luneberg lens to transmit radio frequency signals within a defined region or receive radio frequency signals that originate within said defined region.

11. The directional antenna as recited in claim 10 wherein said transmit radio frequency signals or said receive radio frequency signals bear digital data.

12. The directional antenna as recited in claim 10 wherein said directional antenna is configured to communicate with a second directional antenna to form a point- to-point communication link.
