Optimization and Simulation of Helix loaded with Dielectric Dispersion Characteristics using TLBO Algorithm

In this paper, an analytical theory of dispersion characteristics for Helix loaded with Dielectric (HLWD) has been investigated numerically for fundamental as well as higher-order Hybrid modes (HE and EH) for guided electromagnetic wave propagation. The appropriate value of helix pitch angle, dielectric radius and dielectric constant were found out using Teaching Learning Based Optimization (TLBO) with an aim to get wide single-mode wave propagation bandwidth. This structure can be used to determine radiation characteristics of axial mode helical antenna where radiation is coming out from the end of the aperture. It can be used as a highly directive end-fire antenna that finds potential application in satellite communication.
