Ultra-wideband (uwb) antenna

A device, comprising:

• an antenna ground conductive unit disposed in close proximity to the human body, and configured to have a surface of a geometrical shape substantially equal to a geometrical shape of an inner surface of the dielectric case of the device;
• an antenna radiating unit disposed at a distance from the antenna ground conductive unit;
• a conductive shorting unit configured to connect the antenna ground conductive unit and the antenna radiating unit at predetermined points, and disposed substantially orthogonal to the surface of the human body;
• and
• an antenna conducting feeding unit configured to be connected to the antenna ground conductive unit and the antenna radiating unit at arbitrary points, and disposed approximately orthogonal to the surface of the human body,
• wherein
• at least one of the antenna ground conductive unit and the antenna radiating unit comprise arbitrarily-shaped slits, and
• the antenna ground conductive unit and the antenna radiating unit are mounted on an internal surface of the device, and oriented maximally parallel to the surface of the human body.

An ultra-wideband (UWB) antenna comprising:

• a radiating unit comprising a contour of a first shape;
• a ground unit comprising a contour of a shape substantially equal to the first shape, and disposed parallel to the radiating unit;
• a shorting pin connected orthogonal to the ground unit and the radiating unit to connect a first area of the ground unit and a first area of the radiating unit;
• and
• a feeding unit connected orthogonal to the ground unit and the radiating unit to connect a second area of the ground unit and a second area of the radiating unit.

An antenna, comprising:

• a ground plate comprising a first boundary comprising a straight line extended in a direction of a single side, and a curved second boundary connected to both ends of the single side of the first boundary;
• a radiating plate configured to be disposed substantially parallel to the ground plate, at a distance from the ground plate in a direction orthogonal to a surface of a human body;
• a shorting pin configured to extend in a direction substantially orthogonal to the ground plate and the radiating plate and to connect the ground plate and the radiating plate;
• and
• a feeding pin configured to be connected at arbitrary points of the ground plate and the radiating plate,
• wherein at least one of the ground plate and the radiating plate comprise an arbitrarily-shaped slit.
