Summary:
A FSS (Frequency Selective Surface) which comprises periodic arrays of patches or apertures in a conducting screen and finds important applications as filters in microwaves and optics, is discussed [1]. And it has frequency-band-rejection characteristics or frequency-band-pass characteristics. On the other hand, Artificial Magnetic Conductor (AMC) is a kind of artificial materials, and AMC has PMC (Perfect magnetic conductor) characteristics in a specific frequency. On the PMC surface, incident waves are reflected without phase shift [2][3]. Furthermore, in order to reduce the size of devices on integrated circuits, it has become necessary to use conductive materials having low resistivity and insulators having low dielectric constant to reduce the capacitive coupling between adjacent metal lines. In this paper, a design method for AMC with dielectric layer by using a loop-slot FSS is described. Based on the method, the bandwidth characteristics of a designed AMC with dielectric layer are clarified.
