Shielding screen for integration of multiple antennas

摘要

A shielding screen for use in an integrated antenna system that includes at least two antennas that emit interfering signals that interfere with each other and at least one antenna that emits a non-interfering signal that does not interfere with the interfering signals. The shielding screen incorporates a frequency selective surface configured and dimensioned to reflect the interfering signals and to transmit the non-interfering signals. The shielding screen is positioned between the antennas that emit interfering signals and has a surface disposed substantially orthogonal to a line extending therebetween. The screen is dimensioned to block the interfering signals emitted by each of the two antennas from impinging upon the other of the antennas.
