Abstract

A low profile antenna comprises a radiating element arranged over a ground plane. The radiating element has a plurality of radiating edges. Dielectric elements are coupled to the radiating edges.

Claims

1. A low profile antenna, comprising:

a ground plane;

a radiating element, the radiating element comprising a plurality of radiating edges and a ground facing side, the radiating element separated from the ground plane by a distance d;

at least one dielectric element coupled to each of the plurality of radiating edges on the ground facing side and extending to the ground plane; and

a power feed connected to the radiating element.

2. The antenna of claim 1, wherein the radiating element has a length L and a width W;

and

the at least one dielectric element has a length L₁ and a width W₁ less than L and W.

3. The antenna of claim 2, wherein L is not equal to W.

4. The antenna of claim 1, wherein the antenna operates at multiple frequencies.

5. The antenna of claim 4, wherein the radiating element comprises at least one slot.

6. The antenna of claim 1, wherein the dielectric elements are coupled to the radiating element using conductive tape.

7. The antenna of claim 1, further comprising an impedance matching network.

8. A low profile antenna, comprising:

a ground plane;

a patch radiating element, the patch radiating element comprising a plurality of radiating edges and a ground facing side, the radiating element separated from the ground plane by a distance d;

a plurality of dielectric elements coupled to both the ground plane and the plurality of radiating edges of the patch radiating element; and

a power feed connected to the radiating element.

9. The low profile antenna of claim 8, wherein the patch radiating element comprises a plurality of meanderline elements.

10. The low profile antenna of claim 8, wherein the patch radiating element comprises a plurality of slots.

11. The low profile antenna of claim 8, wherein the patch radiating element comprises a length L and a width W.

12. The low profile antenna of claim 8, wherein the plurality of dielectric elements comprise a length L₁ and a width W₁ less than the length L and the width W.

13. The low profile antenna of claim 8, wherein the length L is not equal to the width W.

14. The low profile antenna of claim 8, further comprising an impedence matching network.

15. The low profile antenna of claim 8, wherein the patch radiating element resonates at multiple frequencies.
