“…In 15 , the effect of chiral substrates, based on left-side elements, on a two-element antenna array input impedance is presented, where a decrease in the quality factor and a shortening effect are noticed. In 18 , a study presents a mathematical model and proposes a method for the electrodynamic investigation of a chiral metamaterial substrate-based microstrip antenna with mirror-asymmetric left-handed conductive spiral inclusions. A characterization of the input impedance is described, where the authors showed that using a chiral substrate causes a shift of the resonant frequency and an important decrease in the quality factor which indicates the possibility of improving the mass-dimensional characteristics of a chiral microstrip antenna.…”

In this paper, we present an analytical study for the investigation of the effects of the magnetoelectric elements of a reciprocal and nonreciprocal bianisotropic grounded substrate on the input impedance, resonant length of a dipole antenna as well as on the mutual coupling between two element printed dipole array in three configuration geometries: broadside, collinear and echelon printed on the same material. This study examines also the effect of the considered bianisotropic medium on the electric and magnetic field distributions that has been less addressed in the literature for antenna structures. Computations are based on the numerical resolution, using the spectral method of moments, of the integral equation developed through the mathematical derivation of the appropriate spectral Green’s functions of the studied dipole configuration. Original results, for chiral, achiral, Tellegen and general bi-anisotropic media cases, are obtained and discussed with the electric and magnetic field distributions for a better understanding and interpretation. These interesting results can serve as a stepping stone for further works to attract more attention to the reciprocal and non-reciprocal Tellgen media in-depth studies.
