Abstract

In this letter the advantages offered by ε‐near‐zero materials as substrates for horizontal dipole antennas near a ground plane are theoretically studied. From the previous work it is known that substrates with extremely low values of permittivity dramatically enhance radiation from horizontal currents over a ground plane. On the other hand, as reported in this letter, frequency dispersion and the finite size of the substrate limit the achievable enhancement in antenna performance.
