Abstract

This paper is concerned on designing and determining the absorption effect of ice-cream sticks pyramidal absorber (ISP absorber). The basic microwave absorber was design by cutting ice-cream sticks into pyramidal shape. In this paper, there are two type of ISP absorber which are coated with palm ash as absorbent material and without coated with absorbent material respectively. The absorption performances are analyzed and simulated by using CST Microwave Studio. The absorber was measured by using arch method for microwave frequency range of 8 GHz to 12 GHz in order to determine the absorption performance. Measured results showed absorber coated with palm ash produced the best performance in terms of signal absorption. This absorber promised green technology and low cost with reliable performance for various communication applications such as anechoic chamber.
