Design of UWB Antennas Integrating Geopolymer Material

Abstract

Two new designs of reduced volumetric ultrawideband antennas (UWB) are proposed in this paper. These antennas are intended to radiate in the air medium over the frequency band of 0.3-3GHz. This work demonstrates that the combination of innovative dielectric materials along with either resistive load or the association of the radiation provided by an electric dipole and a magnetic loop offers an efficient way for reducing antennas dimensions. Furthermore, one of the proposed antenna has been manufactured and validated by the first experimental results.
