Abstract


In a communication industry, lots of improvements and enhancements became common day-by-day; all of those communications are provided to receiving units via proper pattern and structured sharing methodologies. By means of reducing the amplitude deviations, the narrow-beams can be efficiently produced with-respect-to respective space focusing points. There are many beam shaping methodologies and shrinking principles available in the existing researches, but all are similar in certain cases such as: based on the line-oriented projections, linear sharing, Discrete-indexing and so on. This kind of issues is present in indexing procedures, especially when the quantity/size of the beam is huge. In this paper, a new approach is designed to attain efficient beam-shaping principles, which is called as Structured Shaping Methodology (SSM), which is used to convert the shrinked beams into the required beam-shapes. All the past approaches are depending on the linear-beam-sharing scheme with fixed indexing methodology as well as beam patterns are splitted anonymously. The Period Indexing methodology is presented in this paper to efficiently maintain the beam-pattern indexing as well as the SSM is highly effective to transform the beam into required shapes. From all our experimental results shows that our beam-pattern designing scheme such as: Structured Shaping Methodology with Period Indexing is intelligent and efficient to attain better results compare to the available schemes present into the past systems.
