Abstract
A multiple frequency band antenna for a communications device, such as a radiotelephone, includes a dielectric substrate having high and low frequency band radiating elements disposed on a surface thereof. The high and low frequency band radiating elements have meandering patterns and are electrically connected to a feed point. Lumped electrical elements are electrically connected in series between the high and low frequency band radiating elements at the feed point to reduce coupling effects between the high and low frequency band radiating elements.
