Apparatus and methods for wireless communication

An apparatus comprising: a first conductive antenna track, extending between a first end and a second end and defining a loop shape, the first conductive antenna track comprising a first feed point adjacent to the first end and configured to couple to radio frequency circuitry; and a second conductive antenna track coupled to the first conductive antenna track at a first location in proximity to the first feed point, and at a second location between the first end and the second end of the first conductive antenna track, to form a first closed loop configured to resonate in a first operational frequency band.
