Abstract

The present invention provides a low-cost, frequency-tunable, steerable, reflector array (100) capable of simulating the electromagnetic effects of a parabolic or similarly-shaped reflector on a planar or conformal surface. Simple scatterers such as short circuited dipoles, disposed on a geometrically planar or conformal substrate, are configured from a series of scatterer sub-elements, electrically connected serially to one another by MEMS switches (103). These connected scatterer sub-elements from a reflective array disposed above a ground plane (106) on a substrate (104). By properly controlling the length and spacing of the activated dipole elements (102), it is possible to simulate the equiphase reflection profile of a horn feed or sub-reflector feed of a parabolic or similar reflector. In addition, the array may be steered by selectively controlling the scatterer configurations.
