Pyramidal Microwave Absorber Design from Waste Material using Rice Husk and Rubber Tire Dust
Keywords:
Pyramidal Microwave Absorber, Rice Husk, Rubber Tire Dust, Waste MaterialAbstract
Waste material has potential to be used as an alternative material for the microwave absorber that used in the RF anechoic chamber. New material had been research to reduce the cost of designing pyramidal microwave absorber. In this research, rice husk from paddy are mixed with recycled rubber tire dust to give the better reflection loss performance to the pyramidal microwave absorber design. The pyramidal microwave absorber is operating in the microwave frequency range from 7 GHz to 12 GHz. There are three main stage of this work. Firstly, fabricate the waste material pyramidal microwave absorber had been done by using the pyramidal shaped mould. The second work is to determine the dielectric properties of the pyramidal microwave absorber and the last stage is to measure the reflection loss of the waste material using the radar cross section (RCS) techniqueDownloads
