نویسندگان
چکیده
In this paper we investigate comparative analysis of different antenna parameter (directivity, side lobe level and convergence time ) by using different type of optimizing technique such as Taguchi‟s, PSO, RCGA for synthesis of broad side and end fire linear antenna array in WI-MAX application. On ampere current is provided to each element and radiated power is decreases and radiation intensity increases in the given direction. Simulation results show that PSO is better other than other optimizing techniques such as RCGA, Taguchi‟s.

To obtain the optimal solution, thinning is performed by removing some elements in an array thro...
متن کاملPhase Only Synthesis of Antenna Patterns Using Iterative Restoration Methods
In this work, the method of iterative Fourier transform phase reconstruction, conventionally used in holography and optical image reconstruction, is applied to phase only synthesis of antenna patterns. The method is applied to two types of pattern synthesis problems: "main lobe beam shaping" and "side-lobe-level reduction". The proposed method is most useful in the efficient employment of attai...
