Abstract
Reflectarrays are used as a hyperboloidal or ellipsoidal subreflector in dual-reflector antenna systems. The design formulas for reflectarrays acting as hyperboloid are discussed and its location consideration which is important for dual-reflector system is presented. A 48-inch Cassegrain antenna is chosen to demonstrate the application of compact dual-reflector designs. A subreflectarray is designed to emulate a hyperboloidal subreflector and the plots of the reflection phase shift and scattered field of the subreflectarray validate its effectiveness.
