Abstract: A wideband array capable of MIMO operation and possessing low Passive Intermodulation (PIM) characteristics is described for use in Distributed Antenna Systems (DAS) and other applications which require low PIM levels. The antenna can be configured to provide a narrow radiated beamwidth across multiple frequency bands and can support high power levels. A novel antenna design is implemented to populate the array configuration, wherein both fed and counterpoise elements are isolated from the ground plane to provide low PIM performance, while maintaining constant beamwidth across wide frequency ranges.
