<p>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. There are a number of types of antenna which may be employed, including linearly polarised dipole or mono-pole antennaes, which can be physically realised, for example, as a wire conductor; a transmission line structure; a radiating slot structure; or a micro-strip patch antenna. <IMAGE></p> |
