A cellular repeater system is provided. The cellular repeater system includes an outdoor antenna communicatively coupled to a repeater. The outdoor antenna is configured to relay communications from the repeater to a cellular base station. The outdoor antenna includes a plurality of log-periodic antennas rotated relative to one another such that each of the plurality of log-periodic antennas is pointed in a different direction. The cellular repeater system includes a switching device configured to selectively couple one or more of the plurality of log-periodic antennas to a RF transceiver of the repeater in order to configure the outdoor antenna in a plurality of antenna modes. Each of the plurality of antenna modes have a distinct radiation pattern.

An antenna system can include a ground plane and a driven element spaced apart from the ground plane. The antenna system can include a parasitic element disposed proximate to the driven element. The parasitic element can be coupled to the ground plane by a first coupling and a second coupling. The second coupling can be independent from the first coupling. For instance, the first coupling can include one or more tunable components. The second coupling can fix the parasitic element to the ground plane.

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.
