Abstract
The invention concerns a dipole antenna of reduced size and with improved impedance bandwidth. The antenna is preferably formed on a dielectric substrate having a plurality of regions, each having a characteristic relative permeability and permittivity. First and second dipole radiating element defining conductive paths can be selectively formed on first characteristic regions of the substrate having a first characteristic permeability and first permittivity. A reactive coupling element can be interposed between the dipole radiating elements for reactively coupling the first dipole radiating element to the second dipole radiating element.

A dipole antenna with improved impedance bandwidth, comprising:
- a dielectric substrate having a plurality of regions, each region having a characteristic permeability and permittivity;
- a first and second dipole radiating element defining conductive paths and selectively formed on first characteristic regions of said substrate having a first permeability and a first permittivity;
- a reactive coupling element interposed between said dipole radiating elements for reactively coupling said first dipole radiating element to said second dipole radiating element said reactive coupling element coupled to a second characteristic region of said substrate having a second permittivity and a second permeability for providing a desired reactance value for said reactive coupling element;
- and
- wherein said first and second characteristic regions are different from a third characteristic region of said substrate with regard to permeability.
An antenna, comprising;
- a dielectric substrate having a plurality of regions, each having a characteristic permeability and permittivity;
- at least one radiating element defining a conductive path and selectively formed on first characteristic regions of said substrate having a first permeability and first permittivity;
- at least one reactive coupling element interposed between portions of said conductive path separated by a gap, said reactive coupling element coupled to a second characteristic region of said substrate having a second permittivity and second permeability for providing a desired reactance value for said reactive coupling element;
- and
- wherein said first and second characteristic regions are different from a third characteristic region of said substrate with regard to permeability.
