Abstract

This paper investigates TiO₂ loaded metal diagonal and square horn antennas and specific absorption rate (SAR) distributions in a phantom bio-medium due to these antennas through simulation. Diagonal horn is a multimode horn antenna whereas in conventional square horn only TE₁₀ mode propagates. Both diagonal and square horns, which are terminated in a phantom bio-medium are designed and simulated at 2.45 GHz using FEM based Ansoft´s HFSS software. The SAR distributions in the bio-medium due to diagonal and square horns are compared at 2.45 GHz.
