A compact inverted-F antenna having a radiator arm formed from portions disposed in two parallel spaced apart planes and connected together electrically to form a folded meander-line topology. The planes may be defined by the surfaces of a dielectric substrate and the radiator arm may be formed from upper and lower conductive traces printed on either side of the dielectric substrate and interconnected serially through filled via holes. The antenna includes a ground plane parallel to and spaced apart from the radiator arm. The ground plane may be a grid conductive wall formed from filled via holes through the dielectric substrate.
