Abstract: An antenna system for a radio frequency identification system comprising (a) a base (105), a first patch antenna (102) disposed on the base (105) and having a circular polarization and adapted to convert between electrical signals and electromagnetic fields; and a second patch antenna (103) disposed on the base (105) and having a circular polarization and adapted to convert between electrical signals and electromagnetic fields. The second antenna (103) is disposed at a distance from the first antenna (102) to define a region (104) between the first antenna (102) and the second antenna (103). The second patch antenna (103) being oriented relative to the first patch antenna (102) such that the electromagnetic fields of the two antennas are substantially opposing in said region (104).
