Abstract

An antenna is disclosed in which the radiating structure includes a meta-material having frequency selective properties. The frequency selective properties of the meta-material enable multiple antennas each designed for operation at separate frequencies and each having such meta-materials to be placed in close proximity without affecting each other. This can be advantageous if for example a large number of antennas are to be placed in a small area such as on a vehicle or small building.

Claims

1. An antenna comprising:

a primary radiating structure, the primary structure including a meta-material having frequency selective properties, the meta-material having a predetermined frequency of operation, such that the antenna will transmit and receive at the predetermined frequency only, the meta-material impeding current flow in the structure at all other frequencies.

2. The antenna according claim 1, included in a combination within a series of antennae wherein the series of antenna comprises:

a plurality of antenna mounted immediately adjacent each other, each individual antenna having a different predetermined frequency of operation, thereby ensuring that transmitted and received signals from the plural antennae do not interfere with one another.

3. An antenna according to claim 1 in which the meta-material comprises:

a combination of conductive and non-conductive materials.

4. An antenna according to claim 3 in which the conductive material is metallic and the non-conductive material is non-metallic.

5. An antenna according to claim 4 in which the metallic material is copper and the non-conductive material is a printed circuit board substrate.

6. An antenna according to claim 1 in which the predetermined frequency is 50 MHz, 100 MHz, 230 MHz, 420 MHz, or 500 MHz.

7. An antenna according to claim 1 in which the antenna is mounted on a vehicle or other platform.

8. An antenna according to claim 4 in which the metallic material is copper and the non-conductive material is Kapton.

9. An antenna according to claim 2 included in a combination within a series of antennae wherein the meta-material comprises:

a combination of conductive and non-conductive materials.

10. An antenna according to claim 9 included in a combination within a series of antennae wherein the conductive material is metallic and the non-conductive material is non-metallic.

11. An antenna according to claim 10 included in a combination within a series of antennae wherein the metallic material is copper and the non-conductive material is a printed circuit board substrate.

12. An antenna or series of antenna according to claim 11 included in a combination within a series of antennae wherein predetermined frequencies are 50 MHz, 100 MHz, 230 MHz, 420 MHz, or 500 MHz

13. An antenna according to claim 12 included in a combination within a series of antennae wherein the series of antenna are mounted on a vehicle or other platform.

14. An antenna according to claim 13 in which the metallic material is copper and the non-conductive material is Kapton.
