Abstract: The disclosure relates to an antenna including a substrate and a conductor pattern on the substrate. The conductor pattern comprises first and second conductor areas and the first conductor area is generally at a first end of the substrate and the second conductor area is generally at an opposing second end of the substrate. A first direction extends between the first and second ends of the substrate. The first conductor area has two arms, the two first conductor area arms extend parallel to the first direction and define a first slot between them; wherein the second conductor area has two arms with a second slot defined between them, and the two second conductor area arms extend parallel to the first direction. The two second conductor area arms sit within the first slot with a portion of the first slot at the outer sides of the two second conductor area arms.
