Book Description
Distorted beam pattern in array antenna is due to failure of one are more elements in array. Correction in beam pattern is done either through readjusting the weights of remaining healthy array elements or by readjusting phase. Readjusting phase put restriction beam steering which is unacceptable. We can easily correct faulty array pattern without paying much cost by readjustment of weights by different optimization techniques. In this work a new optimization hybrid technique based on firefly & harmony search algorithm in LAA. This optimization algorithm has provided fast and more accurate result in correction as compare to individual firefly and harmony search. This hybrid algorithm has a firefly algorithm feature of finding local maxima in less time and then finding optimum solution from these local maxima by using harmony search algorithm. It is fast enough to be implemented practically. I am proposing to use this hybrid algorithm in 2-diminsional LAA (circular or rectangular) or other type of array antennas. I am also proposing to check this algorithm in more than one faulty element in Linear Antenna Array.
