Novel 3D loops and coils utilizing fourier series for low frequency AMC ground planes

Abstract

Previously developed hybrid genetic programming with low-level optimizer software is used along with two novel building block designs (3D loop and coil utilizing Fourier series) to design low frequency artificial magnetic conductor (AMC) ground planes using only design specifications. The methodology used to create these building block designs in the existing GP software is described, and an AMC design example covering 225-450 MHz is given. The design has 72.9% bandwidth and a thickness of λ0/15.
