Abstract

A hybrid microwave reflective mesh (28) and an antenna reflector having an RF reflecting surface composed of the mesh. The hybrid mesh includes a supporting mesh (34) of any conveniently fabricatable mesh size, which may be substantially larger than the RF wavelengths to be reflected, and a relatively fine, compliant, electrically conductive mesh fabric (36) overlying and secured to the supporting mesh and having a mesh gauge sized to reflect the desired RF wavelengths.
