Abstract

A planar antenna, which is operable within the ultra wide bandwidth, includes a dielectric substrate that has opposite and parallel first and second surfaces, a hexagonal radiating element that is formed on the first surface of the dielectric substrate, a feeding element that is coupled to the radiating element, and a grounding element that is formed on the second surface of the dielectric substrate.

Claims

1. A planar antenna operable within the ultra wide bandwidth, comprising:

a dielectric substrate that has opposite and parallel first and second surfaces;

a hexagonal radiating element formed on said first surface of said dielectric substrate;

a feeding element coupled to said radiating element; and

a grounding element formed on said second surface of said dielectric substrate.

2. The planar antenna as claimed in claim 1, wherein said radiating element has a longer side, a shorter side that is opposite and parallel to said longer side of said radiating element and that has a length shorter than that of said longer side, a pair of opposite first adjacent sides, each of which is adjacent to said longer side, and a pair of opposite second adjacent sides, each of which is adjacent to said shorter side.

3. The planar antenna as claimed in claim 2, wherein said dielectric substrate is generally rectangular in shape, and has a first edge, said longer side of said radiating element being disposed proximate and parallel to said first edge of said dielectric substrate.

4. The planar antenna as claimed in claim 3, wherein said dielectric substrate further has a second edge opposite to said first edge of said dielectric substrate, said feeding element being formed on said first surface of said dielectric substrate, and having a first end connected to said shorter side of said radiating element, and a second end that is opposite to said first end of said feeding element and that is flush with said second edge of said dielectric substrate.

5. The planar antenna as claimed in claim 1, wherein said feeding element is a microstrip line.

6. The planar antenna as claimed in claim 1, wherein said grounding element is generally rectangular.

7. The planar antenna as claimed in claim 1, wherein said radiating element is made from copper foil.

8. The planar antenna as claimed in claim 2, wherein each of said first adjacent sides of said radiating element forms a right angle with said longer side of said radiating element.

9. The planar antenna as claimed in claim 2, wherein each of said first adjacent sides of said radiating element forms an acute angle with said longer side of said radiating element.
