Placement variation is one example of parameters
that critically affects the performance of RF absorbers. In this
work, four designed variation patterns - W, X, Y, and Z were
discussed to compare the reflectivity (Sll) of designed wedge
microwave absorbers. Two sub-shapes were investigated in this
work - straight wedge and oblique wedge, each type having three
variation of top width dimension. The other investigation
includes performance comparison between four and nine
elements' array of straight wedges and oblique wedges. These
wedge absorbers were simulated using CST Microwave Studio
software, with rice husk as its material (dielectric constant, Gr =
2.89). The wedge absorbers have been designed to operate
effectively between the frequencies of 1 GHz to 20 GHz.
