Air and Ferrite Core Loaded Axial Mode Helical Antenna for Completely Filled Cylindrical Water Pipe Network

This paper reports design and performance comparison of an air core and ferrite core loaded axial mode helical antenna for completely filled cylindrical water pipe network at 5 GHz and 500 MHz operating frequency. Due to the finite permeability and permittivity of hexaferrite material, 74.18 % reduction in size has been achieved at 500 MHz. Further, we performed an experimental study for empty and completely filled cylindrical water pipe network. With the help of electromagnetic wave solver CST Microwave Studio, signal transmission distance of 50 meter have been achieved in completely water filled piped network. The gain of the designed antenna is: 10.5 dBi.
