We consider here a periodic microwave absorbing structure based on microwires, embedded in the dielectric layer, which mounts seamlessly on a flat metal plate. For the low period of the cell the frequency dependence of the reflection coefficient from the considered structure proves to be close to that for a structure in a form of the resistive film embedded in or over the dielectric layer. The matching conditions of the structure with free space are obtained. The bandwidth of the radio wave absorber can be tuned for a given maximum reflection by varying the parameters of the structure. The results of the paper can be further used for investigation of broadband microwave absorbing structures including set of conducting grids with squared cells.
