Abstract
Low-profile, compact UWB embedded antenna designs are provided for use with computing devices, such as laptop computers, which enable ease of integration within computing devices with limited space, while providing suitable antenna characteristics (e.g., impedance matching and radiation efficiency) over an operating bandwidth of about 1 GHz to about 11 GHz.
Claims24
An antenna, comprising:
- a first planar radiating element;
- and
- a second planar radiating element comprising a first and a second portion, wherein the first portion comprises a cone tip in the form of a first edge, and wherein the first portion is coplanar with the first planar radiating element;
- wherein the first planar radiating element comprises a first edge that is spaced apart and adjacent to the first edge of the first portion of the second planar radiating element;
- and
- wherein the first and second portions of the second planar radiating element are connected at a bottom edge of the first portion and wherein the first and second portions are angled with respect to each other.

An antenna, comprising:
- a first planar radiating element;
- and
- a second planar radiating element comprising a first and a second portion wherein the first portion comprises a cone tip in the form of a first edge, and wherein the first portion is coplanar with the first planar radiating element;
- wherein the first planar radiating element comprises a first edge that is spaced apart and adjacent to the first edge of the first portion of the second planar radiating element;
- and
- wherein the first planar radiating element comprises a planar strip extending from a top edge thereof.
3 more elements
An antenna, comprising:
- a planar asymmetrical radiating element;
