Abstract: An antenna is provided comprising first (11), second (12) and third (13) line elements dispersed on first, second and third consecutive sides of a rectangle (10). The third line element is longer than the first line element by a length approximately equal to the length of the second line element, thereby providing a radiating portion of the third line element. A feed connector (14) is coupled to the first and third line elements, for applying a radio frequency signal to the antenna for radiating from the second line element and from the radiating portion of the third line element.

Abstract: An antenna (10), illustrated in FIG. 3 , comprises a substrate (11), having an upper surface and and a lower surface, and a transformer (14) having a first conducting track (12) formed on the upper surface and a second conducting track (13), mirroring the first conducting track (12), formed on the lower surface, wherein both first and second conducting tracks have an extremity at opposite ends thereof. The antenna (10) further comprises at least one radiating means, comprising a conducting track on the substrate, and an unbalanced line (20) which provides a first potential (21) and a second potential (22). The first potential (21) and the second potential (22) are coupled centrally (30,31) to said first (12) and second (13) conducting tracks respectively. Furthermore, the at least one radiating means is coupled to one of said extremities.
