Abstract
A system is provided having a first antenna arrangement tuned to communicate within a first radiation pattern and a second antenna arrangement tuned to communicate within a second radiation pattern. In a preferred aspect of the invention, the first radiation path has an inverted conical shape and the second radiation path has a disk shape. The first radiation path is employed to communicate to access points communicating according to the IEEE 802.11 standard and being located above tabletop level. The second radiation path is employed to communicate to access points communicating according to the Bluetooth standard and being located at or below tabletop level. A guard band separates the first radiation path from the second radiation path. The first and second antenna arrangement can be coupled to separate radio devices or can be coupled to the same radio device.
