Antenna Array Design

The standard mobile communication and RADARS increased the standard of life, helping the economy to develop for all the countries. The above important systems operate using one type of the antenna or the other. It is a terminal device, without which the above systems cannot work. It is, therefore of interest, to investigate on the design of some of the important antenna arrays optimally for using in RADAR and Electromagnetic Compatibility (EMC) applications in the present work. Antenna radiation pattern structure is one of the most important specifications in all applications. The work is centred around the pattern synthesis. The arrays are designed to generate required patterns. The work is carried out to generate narrow beams with restricted sidelobe level using Real-Coded Genetic Algorithm and Accelerated Particle Swarm Optimization. The work is also undertaken to synthesize unsymmetric patterns for using with the RADARS used in sea vessel to overcome roll and pitch of the ship due to turbulent waters. it has been possible to control the sidelobes to the desired levels anywhere in visible region.
