The beam forming network offers several advantages when implemented in the optical domain. The major benefits of phased-array antenna systems are their high gain and possibility of electronic beam steering and shaping, which is together called beam forming. A phased-array antenna system consists of multiple antenna elements with corresponding tunable phase shifters or delay elements, and some splitting/combining circuitry. A generic formalism for inputting the results of genetic algorithm tuned filter into a microwave circuit has been developed in this paper. The effect of variation in structural parameters with respect to the thickness of the substrate, the position, length and width of linkage are thoroughly investigated in this paper.
