Abstract
The invention relates to an antenna comprising: an elongate conducting band; an antenna socket; a connection to earth; at least one first capacitive element of adjustable capacitance; and at least one first inductive element in series with the first capacitive element.
Claims22
A device comprising:
- shell comprising a first side, a second side, a third side, and a fourth side, the first side and the opposite second side being shorter than the third side and the opposite fourth side;
- and
- an antenna disposed in the shell, the antenna comprising
- a conducting band;
- an antenna socket attached to the conducting band at a first position;
- a first connection linking the conducting band to earth through a first inductor attached at a second position;
- a second connection linking the conducting band to earth through a first variable capacitor of adjustable capacitance, the second connection being attached at a third position, wherein the first position is between the second position and the third position;
- and
- a third connection linking the conducting band to earth through a second inductor attached at fourth position, wherein the fourth position is disposed between the first position and the third position, wherein the conducting band is insulated from remaining portions of the shell by insulating portions.
