Abstract

An efficient genetic algorithm/method of moments formulation using curved segmentation (GA/MoM-CS) to optimize the curl and helical antenna structures is implemented and employed to design and optimize complex helical wire antennas such as tapered single helical antenna (TSHA), single elliptical curl antenna (SECA) and tapered quadrifilar antenna (TQFA) mounted over infinite ground plane. An optimum gain, VSWR and circular polarization properties that make these antennas suitable to be used in satellite communications systems are obtained. The numerical results show that the hybrid GA/MoM-CS produces superior antenna designs for such complex geometries with reduced computation time compared to codes that uses straight wire segmentations.
