Abstract

An ultra-wideband antenna having an isotropic radiation pattern includes a support plate, a feed line on the support plate, a radiating element connected to the feed line to transmit and receive signals, and a ground plate spaced apart from the feed line and attached to the support plate. The radiating element has at least two intersecting conductive plates.

Claims

1. An ultra-wideband antenna, comprising:

a support plate;

a feed line on the support plate;

a radiating element connected to the feed line, the radiating element for transmitting and receiving signals, the radiating element including at least two intersecting conductive plates; and

a ground plate spaced apart from the feed line and attached to the support plate.

2. The ultra-wideband antenna as claimed in claim 1, wherein the support plate is a printed circuit board (PCB) or an epoxy substrate.

3. The ultra-wideband antenna as claimed in claim 1, wherein the feed line and the ground plate constitute a co-planar waveguide (CPW) structure.

4. The ultra-wideband antenna as claimed in claim 3, wherein the feed line is inserted into a groove formed on the support plate.

5. The ultra-wideband antenna of claim 1, wherein the feed line is installed on a front face of the support plate and the ground plate is coated on a rear face of the support plate.

6. The ultra-wideband antenna as claimed in claim 1, wherein the at least two conductive plates intersect vertically.

7. The ultra-wideband antenna as claimed in claim 1, wherein the at least two conductive plates have a same shape.

8. The ultra-wideband antenna as claimed in claim 1, wherein the at least two conductive plates have different shapes.

9. The ultra-wide band antenna as claimed in claim 1, wherein at least one of the two conductive plates is rotatable.

10. The ultra-wideband antenna as claimed in claim 1, wherein the at least two conductive plates intersect obliquely.

11. The ultra-wideband antenna as claimed in claim 1, wherein a position of one of the at least two conductive plates is matched with a position of the ground plate.
