Abstract
The present invention provides a compact antenna system having multiple antennas exhibiting polarization and pattern diversity. The system comprises at least two antennas which may have different polarizations, operatively coupled to a passive element which operates as a Balun for a first antenna and which is configured to absorb and re-radiate electromagnetic radiation from the second antenna to produce a desired radiation pattern. The present invention also provides for additional antennas operatively coupled to the passive element or to the first antenna to provide additional diversity.
