Abstract: Since high bit rate for data transmission is required for broadband internet, High Definition TVs (HDTV) and other services, Power-Line Communications (PLC) are a technology that provides a very high-speed digital data transmission using the regular Low Voltage (LV) power lines as the transmission media. With multiple outlets in almost every room, power lines are already the most pervasive network in the home and this will reduce the cost for realization of new telecommunications networks.

Abstract: The inner shorted annular microstrip antenna (ISAMSA) is one of the different types of microstrip patches which are widely-used for their numerous advantages. These antennas have the advantage of controlling the radiation pattern by varying the inner and outer radius in the same mode .This thesis presents a study of the design parameters of inner shorted annular microstrip antennas such as the input impedance, the bandwidth, the radiation pattern and the modes that can be excited in this type of antennas using EM-Sight of Microwave Office 2000.

Abstract: This study presents an electronic circuit design system based on Genetic Algorithm that uses SPICE to evaluate the circuit performance and compare it to the requirements. A Parallel Genetic Algorithm is used to reduce the running time as the simulator takes very long time to process a circuit. The Genetic Algorithm was implemented using the C++ programming language, to have an efficient and reliable program and to allow the use of low level functionality of the operating system. The implementation was targeted in the Windows operating system.
