An antenna can include a dielectric substance (130), a radiator element (105) and a radio frequency feed point (135). As an example, the radiator element (105) can have at least a first portion (110) and a second portion (115) coupled to one another and folded about the dielectric substance (130). In one arrangement, the radiator element (105) can be split into a plurality of radiator branches (120, 125) in at least one of the first portion (110) and the second portion (115) of the radiator element (105).
