Abstract

A cone-based multi-layer wide band antenna is provided, including a cone-based member having a multi-layer structure. The multi-layer structure includes a first layer conical structure, and the first layer conical structure has a height and a base radius configured to provide a desired impedance of the antenna.

First claim

What is claimed is:

1. An antenna, comprising:
a cone-based member having a multi-layer structure and multiple layers of conical structures, wherein:
the multi-layer structure includes a first layer conical structure, and the first layer conical structure has a height and a base radius configured to provide a desired impedance of the antenna;
the multiple layers of conical structures are configured over the first layer conical structure; and
the multiple layers of conical structures and the first layer conical structures are arranged such that the antenna has a cross-sectional shape with a large scale virtual curvature at one or more sides, wherein non-uniform meander lines are arranged along the large scale virtual curvature.

2. The antenna according to claim 1 , wherein:
the cone-based member further includes multiple layers of conical structures over the first layer conical structure, and
the multiple layers of conical structures and the first layer conical structure are arranged such that the antenna has a cross-sectional shape with a large scale curvature at one or more sides.

3. The antenna according to claim 2 , wherein:
the first layer conical structure is a cone, and
the multiple layers of conical structures are truncated cones.

4. The antenna according to claim 1 , wherein:
the first layer conical structure is a cone, and
the multiple layers of conical structures are circular discs.

5. The antenna according to claim 1 , further comprising:
an inverted cone-based member symmetric to the cone-based member,
wherein a source is disposed between the cone-based member and the inverted cone-based member.

6. The antenna according to claim 5 , further comprising:
a top-loaded plate on top of the cone-based member, and
a bottom-loaded plate under the inverted cone-based member.

7. The antenna according to claim 6 , wherein:
each of the top-loaded plate and the bottom-loaded plate is non-flat.

8. The antenna according to claim 1 , wherein:
different meaner lines are configured to allow the antenna to operate at different frequency bandwidths.

9. The antenna according to claim 1 , further comprising:
a ground plane,
wherein a meander line structure is configured in the ground plane to form a resonating structure on the ground plane.

10. The antenna according to claim 9 , wherein:
holes are drilled on the ground plane to enhance antenna tuning and reduce a weight of the antenna.

11. The antenna according to claim 1 , further comprising:
a top-loaded plate having a flat surface.

12. The antenna according to claim 1 , further including:
a top-loaded plate having a non-flat surface,
wherein the top-loaded plate includes a plurality of concentric annuli or the top-loaded plate includes a meander line structure.

13. The antenna according to claim 1 , wherein:
the desired impedance of the antenna matches a transmission line or a source that feeds an electric signal to the antenna.
