Synthesis of Conical Conformal Array Antenna Using Invasive Weed Optimization Method

Invasive weed optimization (IWO), which shows high performance in the electromagnetic community, is used to synthesize the conical conformal array antenna in this paper. Radiation pattern of the conformal array antenna is obtained by the superposition of the active element radiation pattern in the presence of platform, which includes the mutual coupling information of the array antenna and effects of the platform. Compared with partial swarm optimization (PSO), performance of IWO is more stable and lower side-lobe is obtained with IWO. A linear antenna array mounted on conical carrier is optimized and fabricated, measured results agree well with the optimized results. In addition, the proposed method can be used for the pattern synthesis of any kind of antenna array. Index Terms Conical conformal array antennas, invasive weed optimization, and radiation pattern.
