Microstrip patch antennas represent one family of compact antennas that offer a conformal nature and the capability of ready integration with communication system's printed circuitry. This paper highlights a constructed of 2.4 GHz of a coaxial - fed rectangular spiral microstrip patch antenna for WLAN application where it's mounted on a high frequency(More)
This paper investigates the capability of oil palm ash paint as green-absorbing material in a way to absorb microwave radiations. The paint is coated on three different wall materials which are elephant board, plywood and cement. The absorb performance of the paint is observed using the simulation result of Computer Simulation Technology (CST) Microwave(More)
This paper is to focus on to design of the basic geometry of helical antenna in small size at frequency 2.46 GHz. Several parameters dimensions and helical profiles were studied in order to obtain a suitable frequency range. The software that was applied for this simulation is the CST Microwave Studio (CST MWS) which is analytical tool that provides an(More)
The purpose of this paper is to study a mathematical formulation of a water level control loop in a process control training system. Mathematical modeling was carried out to understand the dynamics of the water level changes in the water tank for different settings of the PID controller mode. The idea of transfer function was used to represent the physical(More)
In order to deal with more and more serious problem of microwave radiation pollution, palm oil biomass cement based microwave absorber is needed in order to prevent the buildings from the microwave radiation coming from telecommunication towers. This paper describes the capability of palm oil biomass waste from palm oil fuel ash (POFA) as an absorbing(More)
