Effect on source signal condition for pyramidal microwave absorber performance
(Institute of Electrical and Electronics Engineers (IEEE), 2010-05-11)
In designing a microwave absorber for anechoic chamber, there are many condition can affect the performance of microwave absorber. In this work, four conditions are discussed to compare the reflectivity or S11 of the ...
Parametric studies of the pyramidal microwave absorber using rice husk
(Institute of Electrical and Electronics Engineers (IEEE), 2010)
Agriculture waste has potential to be used as an alternative material for the microwave absorber used in the anechoic chamber. Compared to the current materials used, such as polystyrene and polyurethane, agricultural waste ...
Reflection loss performance of hexagonal base pyramid microwave absorber using different agricultural waste material
(Institute of Electrical and Electronics Engineers (IEEE), 2010-11-08)
Hexagonal base pyramid microwave absorber is the new design of microwave absorber. In this work, two sub-shapes are considered to compare it reflection loss performance. The shapes are hexagonal and truncated hexagonal ...
Microwave wedge absorber design using rice husk - An evaluation on placement variation
(Institute of Electrical and Electronics Engineers (IEEE), 2010-04-12)
Placement variation is one example of parameters
that critically affects the performance of RF absorbers. In this
work, four designed variation patterns - W, X, Y, and Z were
discussed to compare the reflectivity (Sll) ...
Investigation on the CCSRR influences towards CSMA with air gap for HAPS
(Institute of Electrical and Elctronics Engineering (IEEE), 2010)
A circular profile microstrip antenna and its related structural dimensions meant for 5850 -7075 MHz Malaysia HAPS operating band are investigated here. Appearing by three layers and having layer three surface copper ...
Investigation of complementary split ring resonators with dielectric ring
(Institute of Electrical and Electronics of Engineering (IEEE), 2010-11-08)
This paper present development in relation to a wideband antenna comprising a disk antenna and a plurality of circular split ring resonators coupled with a high dielectric ring. Using slotted resonators together with ...
