Inverted triangle absorbing properties on hollow pyramidal microwave absorber

This study investigates about the new design titled as inverted triangle hollow pyramidal microwave absorber. Four stages have been developed in this study based on Sierpinski triangle theory. The parameters that involve in this research are design structure, dimensions of an absorber and coated factor. The processes that involves in this project are design simulation, development and measurement. The data from simulation has been used to analyze and compare which stage has better absorption performance in CST Studio software. The arch measurement method at frequency 8 GHz till 12 GHz determines the different of absorption performance develops by the four stages. The data from simulation and measurement determine which parameters can affect the absorption performance. The measurement result shows the highest absorption performance is -56.72 dB. This work of study showed that Stage IV design attained the highest absorption rate, while followed by Stage III, Stage II and Stage I sequentially order of highest absorption rate. The result shows the inverted triangle hollow pyramidal shaped of microwave absorber produces excellent performance and applicable for anechoic chamber system.
