## Abstract In this article, a novel miniaturized dual‐band frequency selective surface (FSS) with close band spacing is presented, in which each periodic cell consists of double square loops with different capacitive loadings. The dimension of the unit cell is miniaturized by loading with ceramic

Abstract
A pin diode‐loaded active doubly periodic flat strip FSS is shown to act as a dynamic screen. It is shown that by means of d.c. bias control, we can utilize the screen in, (1) transmission mode as a dual band electromagnetic shutter, or with the inclusion of a ground plane in reflection mode, as (2) a dual band refection canceller, (3) an amplitude shift keying (ASK) spatial modulator. The properties of the FSS are characterized using a specially designed parallel plate waveguide simulator that permits normal incidence excitation of the FSS under test. © 2009 Wiley Periodicals, Inc.
