TITLE ADAPTIVE ARRAY ANTENNA INVENTOR Robert Milne ABSTRACT OF THE DISCLOSURE A small linearly polarized adaptive array antenna for communication systems is disclosed. The directivity and pointing of the antenna beam can be controlled electronic- ally in both the azimuth and elevation planes. The antenna has low RF loss and operates over a relatively large commu- nications bandwidth. It consists, essentially, of a driven .lambda./4 monopole surrounded by an array of coaxial parasitic elements, all mounted on a ground plane of finite size. The parasitic elements are connected to the ground plane via pin diodes or equivalent switching means. By applying suitable biasing voltage, the desired parasitic elements can be electrically connected to the ground plane and made highly reflective, thereby controlling the radiation pattern of the antenna.
