In this work, rice husk material from paddy had been used as the main material to fabricate the truncated pyramidal microwave absorber. To increase the reflection loss performance, square flower split ring resonator (SF-SRR) had been incorporated onto the rice husk truncated pyramidal microwave absorber. This SF-SRR structure had been located at the top part of the truncated pyramidal microwave absorber...
In this work, a modified Minkowski patch antenna had been designed for 2.4 GHz of resonant frequency, fr for wireless local area network (WLAN) application. The proposed complimentary structure of quadruple P-spiral split ring resonator (QPS-SRR) into the patch antenna had been increasing the gain performance. Other parameters that had been considered in this work are return loss, bandwidth, radiation...
Sugar cane bagasse as is potential agricultural waste to produce an alternative and beneficial product for any suitable application such as pyramidal microwave absorber for anechoic chamber testing application. In this work, the dielectric properties (dielectric constant and tangent loss) of the sugar cane baggase had been measured using the dielectric probe measurement. The sugar can bagasse pyramidal...
Abandoned agricultural waste pose a risk to the environmental and public health. The polyurethane and polystyrene material for designing pyramidal microwave absorber are expensive and not environmental friendly. Tropical crop residue has potential to be used in the electromagnetic testing area. Nowadays, electromagnetic absorbing materials have been increasingly important in ensuring successful Radio...
