Printed Conformal Antenna Design

In many applications pertaining to missile, satellite, spacecraft and aircraft a directive antenna mounted on a curved body is required. Conforming the antenna to the surface save space and is often essential for structural reasons. An antenna that conforms to a surface whose shape is determined by considerations other than electromagnetic; for example, aerodynamic or hydrodynamic called conformal Antenna. Microstrip antenna technology is most suitable for conformal applications because of their ability to conform to non-planar structures. Microstrip antenna patches are placed above what may be characterized as a conducting plane with a dielectric substrate separating the patch from the conducting planeThe properties of such an array depend strongly on whether it is small compared to the radius of curvature of the mounting body, in which case it behaves nearly like a planner array or whether it is comparable or large to the radius.
