A Broadband 3D Printed Fractal Tree Monopole Antenna
By
Progress In Electromagnetics Research C, Vol. 86, 17-28, 2018
Abstract
A broadband monopole antenna is presented, with a radiating body consisting of a fractal tree with three-dimensional conical branches. The effect on polarization and return loss of varying the number of branches, as well as the number of fractal iterations, is explored and presented. The best-case antenna, having five branches and three fractal iterations, was fabricated using a 3D-printed form covered in conductive spray paint. The return loss of this antenna was shown in both simulation and measurement to be better than -10 dB from 1.22 GHz to 24.1 GHz, a bandwidth of more than 180%.
