Abstract

This project is about the design and method in developing a low cost, reliable and good performance microwave absorber for the application in anechoic chamber room measurement. Theoretically, the absorber is designed to be functioning at frequency range from 1.5GHz to 15GHz and in pyramidal-shaped.However due to the equipment limitation for measurement, the absorber is only tested for 2GHz and 1OGHz frequency. A survey on materials that can be used to coat the absorber has been carried out and variety of the materials was tested.The absorbers are made from polystyrene, which were cut into a shape and then coated with carbon. The measurement of the pyramidal absorber was done in order to determine its performance. The absorber that has been developed is called low cost absorber.
