ABSTRACT:
A planar diversity antenna for communications devices, such as radiotelephones, has two radiating elements secured to opposite sides of a dielectric substrate. One radiating element is parasitically coupled to a fed radiating element to resonate at respective adjacent frequency bands. Each radiating element has a meandering electrically conductive path. The planar diversity antenna is maintained in spaced apart, generally parallel relationship with a ground plane within a radiotelephone.
