Artificial Dielectric Superstrate Loaded Antenna for Enhanced Radiation Performance
By
Progress In Electromagnetics Research M, Vol. 85, 185-194, 2019
Abstract
This paper presents a novel engineered artificial dielectric superstrate for improving the radiation characteristics of a CPW-fed planar antenna. Even though the permittivity of the material used for the superstrate is only 4.4, it attains an effective permittivity of more than 18 because of the periodic pattern printed on it. Due to the high value of effective permittivity an improvement in radiation pattern, impedance matching and gain of the antenna are obtained. From the measured results an impedance bandwidth of 374 MHz from 2.453 GHz to 2.827 GHz is observed for the antenna loaded with superstrate. The periodic pattern is fabricated on a substrate of thickness 1.6 mm, and it occupies an area of 56.45×42.48 mm2.
