Abstract

A conformal miniaturized patch antenna with enhanced bandwidth and efficiency is designed based on an artificial anisotropic meta-substrate composed of magneto-dielectric and dielectric materials. The antenna is designed to operate at 300 MHz band. For comparison purposes, different substrate combinations including dielectric, magneto-dielectric, two-layer magneto-dielectric and dielectric, and four-layer periodic magneto-dielectric and dielectric are investigated, and their performances are evaluated at the operating frequency. It is demonstrated that four-layer meta-substrate can effectively decrease the size and increase the bandwidth and efficiency of the antenna in comparison with the other studied host substrates. Numerical studies are performed on the performance of the designed antenna under structural deformation scenarios such as bending to corroborate for its potential use in conformal applications. It was observed that the wideband performance of the antenna is well preserved even after structural deformation while enhancing the efficiency significantly. The conformal magneto-dielectric meta-substrate antenna features a 5.9% matched bandwidth, 1.38 dBi gain, and 60 % efficiency at 300 MHz.
