Abstract

Claims (30)

1 . An ultra wide band (UWB) antenna formed from a single piece of material, the UWB antenna comprising:

a planar portion arranged above a ground plane;

an aperture through the planar portion;

a ground connecting portion formed from cutting of the aperture and configured to electrically connect the UWB antenna to the ground plane; and

a tapered portion configured to be electrically connected to a feed,

the tapered portion extending around at least 40 percent of a periphery of the planar portion and extending from the planar portion toward the ground plane,

wherein a height of the tapered portion decreases around the periphery of the planar portion moving away from the feed, and

wherein a lower edge of the tapered portion is spaced from the ground plane by a gap.

2 . The UWB antenna of claim 1 further comprising a radio frequency (RF) balun.

3 . The UWB antenna of claim 2 wherein the aperture is disposed closer to where the RF balun than a location of an end of the tapered portion.

4 . The UWB antenna of claim 1 wherein a first width of the aperture is within a predetermined percentage of a second width of the planar portion.

5 . The UWB antenna of claim 4 wherein the predetermined percentage is 25-60 percent.

6 . The UWB antenna of claim 5 wherein the predetermined percentage is 30-55 percent.

7 . The UWB antenna of claim 1 wherein the ground connecting portion includes an edge where the ground connecting portion is folded away from the planar portion and toward the ground plane.

8 . The UWB antenna of claim 7 further comprising a radio frequency (RF) balun,

wherein an angle between (a) the edge where the ground connecting portion is folded away from the planar portion and toward the ground plane and (b) a second edge of the planar portion adjacent to the RF balun is within a predetermined angle range.

9 . The UWB antenna of claim 8 wherein the predetermined angle range is 90 to 165 degrees.

10 . The UWB antenna of claim 8 wherein the predetermined angle range is 130 to 160 degrees.

11 . The UWB antenna of claim 1 wherein the tapered portion extends toward the ground plane and is perpendicular to the ground plane and the planar portion.

12 . The UWB antenna of claim 1 wherein the tapered portion extends toward the ground plane and is non-perpendicular to the ground plane and the planar portion.

13 . The UWB antenna of claim 12 wherein at least one of the ground connecting portion and the tapered portion is 3 to 10 degrees from being perpendicular to the planar portion and the ground plane.

14 . The UWB antenna of claim 1 further comprising:

a radio frequency (RF) balun; and

a slot disposed between the RF balun and the planar portion.

15 . The UWB antenna of claim 14 wherein the slot is disposed between the RF balun and the aperture.

16 . The UWB antenna of claim 14 further comprising a second slot disposed on an opposite side of the planar portion as the slot.

17 . The UWB antenna of claim 1 , wherein the height of UWB antenna corresponds to approximately 1/20 of a wavelength corresponding to a target lowest operating frequency of the UWB antenna.

18 . The UWB antenna of claim 1 , wherein the height of the tapered portion monotonically decreases moving away from the feed.

19 . The UWB antenna of claim 1 wherein the planar portion, the ground connecting portion, and the tapered portion are made of an electrically conductive material.

20 . A vehicle comprising the UWB antenna of claim 1 .
