Abstract

A Vivaldi-Monopole antenna is a small form ultra-wideband antenna configured for low frequency operation in modern wireless devices. The Vivaldi-Monopole antenna comprises a tapered-slot element and a monopole element, wherein current modes of each element are combined to yield a functional and small form ultra-wideband antenna configured for low frequency resonances.

First claim

What is claimed is:

1. An antenna, comprising:
a rectangular conductor volume extending along a longitudinal axis from a rear-side edge to a front-side edge;
said conductor volume further comprising:
an aperture disposed adjacent to the rear-side edge, the aperture having a center thereof disposed along the longitudinal axis;
a first slot extending from the aperture toward a center of the rectangular conductor volume, the first slot dividing the conductor volume into a first conductor portion disposed on a first side of the first slot and a second conductor portion disposed on a second side of the first slot opposite of the first side, at least the first conductor portion being tapered toward a side-edge of the conductor volume;
the first slot defining a tapered slot element; and
a third conductor portion extending about at least a portion of the front-side edge from the longitudinal axis toward the side edge, the third conductor portion defining a monopole element.

2. The antenna of claim 1 , wherein said antenna is formed on a dielectric substrate.

3. The antenna of claim 2 , wherein said dielectric substrate is a flexible substrate.

4. The antenna of claim 3 , wherein said flexible substrate comprises a kapton polyimide substrate.

5. The antenna of claim 1 , wherein said tapered slot element is configured for one or more high-band resonances, said high-band resonances within the range of 1600 MHz and 6000 MHz.

6. The antenna of claim 1 , wherein said monopole element is configured for one or more low-band resonances, said low-band resonances within the range of 700 MHz and 900 MHz.

7. The antenna of claim 1 , wherein said first conductor portion is further separated form said second conductor portion by a first gap extending from the aperture to the rear-side edge of the conductor volume.

8. The antenna of claim 7 , wherein said first conductor portion is coupled to said second conductor portion by a low pass filter coupled therebetween.

9. The antenna of claim 7 , wherein said first conductor portion is coupled to said second conductor portion by a resistor coupled therebetween.

10. The antenna of claim 7 , wherein said second conductor portion is separated from said third conductor portion by a second gap.

11. The antenna of claim 10 , wherein said second conductor portion is coupled to said third conductor portion by a high pass filter coupled therebetween.

12. The antenna of claim 10 , wherein said second conductor portion is coupled to said third conductor portion by a resistor coupled therebetween.

13. The antenna of claim 1 , wherein said monopole element is separated from said tapered slot element by a lateral slot; wherein said lateral slot is oriented perpendicular to the longitudinal axis.
