“…In this example a central position of the vias has been selected. The use of vias in other positions will provide a more compact structure if required [3].…”

“…There are two possibilities to this aim. The first one is to compute the dispersion diagram of the infinite structure in the "soft" direction as in [3]. Another simpler option is to compute the transmission coefficient S 12 of a finite structure composed of a few periods and see at which frequency the stop band is located.…”

“…It is noted that the resulting structure is relatively compact but if desired, the strip width could be further reduced by modifying other parameters [3], such as further increasing the period of the vias p or placing the vias at the edge of the strips instead of in the middle.…”

“…In this sense, the planar soft surfaces [3] can be as well convenient as its design is simple. Moreover, they have an additional characteristic derived from their above-mentioned anisotropy; within the frequency band where they suppress the surface waves, they behave differently for the two polarizations, namely vertical and horizontal with respect to the surface.…”

Abstract-In this work, we propose to use a type of periodic structures, the soft surfaces in their planar version, to reduce the back radiation of patch antennas. A key aspect of these surfaces when compared to other periodic structures is their anisotropy which provides different behaviour for different field polarization (horizontal or vertical). This make them especially convenient for this application, as the soft surfaces force the field intensity for any polarization to be zero on the surface for waves propagating along the surface. In this paper, a design example is presented and the back radiation reduction by using planar soft surfaces is demonstrated.

“…However, EBG/HIS offers more degrees of freedom in controlling wave propagation, scattering from all directions and wide angles of incidence compared with soft surfaces [11]. The unit cell size is defined along the direction of soft, P s , as shown in Fig.…”

Abstract-A new thin electromagnetic soft surface of strips in which ledge edges are used to reduce the strip period width and in turns a miniaturized structure is achieved. The surface is tested to reduce the mutual coupling between microstrip patches separated by a half wavelength in free space (center-tocenter). A 20% relative bandgap bandwidth is achieved. The measurements revealed good agreement with the simulated results.
