Abstract
The present invention discloses a novel PIFA-edge antenna and diversity antenna system operable over a wide range of conditions and exhibiting superior performance as part of a wireless LAN environment. The antenna of the present invention provides reliable and consistent omnidirectional performance while reducing the deleterious effects of multipath propagation interference which is often present in office environments having a variety of surfaces that passively reflect a broad range of frequencies useful within the broad spectrum the electromagnetic radiation (e.g., radio frequency or “RF”) for transmitting analog or digital voice, data, images, and the like (herein “data”) typically transmitted across the typical LAN.
