ABSTRACT:
A communications apparatus, includes a housing (40) containing a printed circuit board (PCB) (12) having a ground plane (16) and electronic components in rf shields (18) thereon. A planar antenna (10) is mounted spaced from the ground plane and a dielectric (14) is present in a space between the PCB and the planar antenna. A feed (36) couples the planar antenna (10) to the rf components.
