Abstract

In this paper, polymer magneto-dielectric (PDMS-Fe₃O₄) is proposed as a new substrate for multilayer microstrip antenna array for enhancement of bandwidth, gain, and overall efficiency. Nanoparticles of iron oxide (Fe₃O₄) have been composited with polymer matrix of polydimethylsiloxane (PDMS) to build up the polymer magneto-dielectric layer (PDMS-Fe₃O₄). Polymer magneto-dielectric (PDMS-Fe₃O₄) layer was covered by pure polymer PDMS layers to provide the proposed antenna array with flexibility features. The simulation results of the proposed multilayered antenna array show an excellent enhancement in term of bandwidth (up to 2.416 GHz) and improvement in the efficiency of the antenna array compared to the conventional substrates FR-4 and Rogers.
