Abstract
An antenna structure including an antenna 10 with an outer main surface 11, where said antenna 10 is integrated in a surface of a surrounding material 20. Further comprising a transition zone 30 arranged along the perimeter of the main surface 11 and overlapping the main surface, where the transition zone 30 comprises a layer of a resistive material with a resistivity that varies with the distance from an outer perimeter of the transition zone 30 to enable a smooth transition of the scattering properties between the antenna 10 and the surrounding material 20.

An antenna structure, comprising:
- an antenna with at least one outer main surface,
- said antenna is integrated in a surface of a surrounding material,
- a transition zone arranged along the perimeter of said main surface and overlapping said main surface,
- said transition zone comprising a layer of a resistive material configured with a resistivity that varies with the distance from an outer perimeter of said transition zone to enable a smooth transition of the scattering properties between the antenna and the surrounding material.
An antenna structure for integration in a surface of a surrounding material, said antenna structure comprising:
- an antenna with at least one main surface;
- a transition zone arranged along the perimeter of said main surface and overlapping said main surface;
- said transition zone comprising a layer of a resistive material adapted to have a resistivity that varies with the distance from an outer edge of the transition zone to enable a smooth transition of the scattering properties between the antenna and the surrounding material.
A method of improving the scattering properties of an antenna with at least one outer main surface, where said antenna is integrated in a surface of a surrounding material, said method comprising:
- providing a transition zone along the perimeter of said main surface and overlapping said main surface,
