Abstract

In this work we study the potential to decrease the resonant frequency of a high‐impedance surface (HIS) formed by a periodically slotted screen and a metal ground plane for the case in which the structure's horizontal period and vertical thickness are fixed. The slotted screens, whose slits are shaped as Jerusalem crosses (JCs) have been studied in the literature as uniplanar photonic band‐gap (PBG) structures for surface waves and as the HIS (when the ground plane is added). We modify the geometry of the slit for the fixed period and show that this leads to a certain decrease in the resonant frequency, which means that the proposed structure can be used as a magnetic wall at lower frequencies. Also, we show that our modification allows the structure thickness for a fixed grid period and resonant frequency to decrease by 30%. © 2004 Wiley Periodicals, Inc.
