An antenna comprising an antenna feed element, a dielectric structure comprising a first end portion, a second end portion and a central portion extending between the first and second end portions which at least partially surrounds the antenna feed element, and a groundplane provided on the first end portion of the dielectric structure, wherein the central portion of the dielectric structure tapers from at least one of the first and second end portions of the dielectric structure towards an other of the first and second end portions of the dielectric structure. An antenna system comprising a plurality of antennas of the invention, wherein each antenna emits electromagnetic signals to at least one other antenna, and when used in conjunction with a body, the plurality of antennas may be positioned adjacent the body at spaced locations of the body. The body may comprise a human body and the antennas may be attached to the body or to a covering on the body. The antenna system may then comprise a wearable antenna system. |
