Optimization of conical antenna array synthesis using modified cuckoo search algorithm

摘要

This thesis presents a modelling of conical antenna array (CAA) and synthesizing this array for a radiation pattern using modified cuckoo algorithm (MCS). Conventional arrays are also taken up as a preliminary study and optimisation of basic geometrics like linear and circular antenna arrays. The modelling carried out by tuning the antenna array parameters like amplitude excitation, complex amplitude excitation and angular distance. Analysis on the conventional and conformal geometries are carried out aiming for a desired pattern. Analysed simulation results gives the insight that, modelled conical array gives the pattern comprising of directivity, HPBW and SLL. Further commercial software package (CST) is used to design a working prototype model. The practical element chosen for the CST model is a dipole patch. The proposed technique is verified with the publishes literature results.
