Abstract   MATLAB is a multi-paradigm numerical computing environment and proprietary programming language developed by MathWorks. MATLAB allows matrix manipulations, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other languages. MATLab is a powerful graphical calculator which is used to design calculator with a help of Graphical user interface GUI. ...

Abstract The effect of wireless electronics in the hospital increased. Research conducts some hospitals shows the risk of the radio frequency interference with the other equipment in hospital. Signals coming from wireless devices can cause malfunction to some medical equipment such as MRI, CT SCAN and X-ray. To solve this problem, ISM band detection system is used to detect radio frequency from mobile phones. The system consists of three LEDs which shows the level of the emissions from the risk to the safe. Meaner line antenna designed to operate at frequency of 2.4GHz with a help of CST studio software. The hardware part is used microcontroller to check and compare the results from the software.

Abstract In wireless communications systems, harmonics and unwanted frequency other than designed one becomes a dominant factor in limiting quality and capacity of transmitted or received signal. Rectangular spiral antenna (RSA) is designed in order to obtain the required parameter responses at 2.45 GHz for Wifi application. RSA of length 16cm and width 20cm is designed on the substrate dielectric ...
