  • Antenna array
    Publication number: 20020175862
    Abstract: An antenna array achieves a high degree of isolation between a plurality of collocated antennas through a combination of electrical polarisation and mechanical alignment. The antenna array consists of three surfaces arranged in mutually orthogonal planes, each surface supporting a planar antenna, wherein each antenna is orthogonally polarised with respect to antenna on other surfaces. Each antenna is linearly polarised to provide a linearly polarised radiation field.
