Sažetak
Printed periodic structures can be used to control the propagation behaviour or the boundary conditions of electromagnetic fields. Under certain circumstances, frequency selective surfaces (FSS) printed on grounded dielectric slab can behave as artificial magnetic conductors (AMC) [1]. When used on the vertical walls of a waveguide, they may realize so-called quasi-TEM [2] or hard waveguides [3], regardless of the cross-sectional shape and size. Such waveguides support a uniform plane-wave at the TEM frequency. Hence, they can be made compact, offering applications e.g. as radiating open-ended elements in multifunction multiband array antennas [4]-[5]. An alternative to the common Jerusalem crosses is to use rectangular strip dipoles the elements of the FSS-loaded waveguide. The purpose of this paper is to present both theoretical and experimental studies of these when applied in quasi-TEM waveguides. The theoretical work is done by simulations in CSN Microwave Studio as well as by in-house moment method codes using multilayer Green’ s functions. The experimental studies are done by two methods : one by obtaining the dispersion diagram from measured transmission coefficient (S21) of the waveguide and the second one which involved measurement of vertical component of the electric field across the waveguide. The theoretical and experimental results agree well.
