Original low-dimensional X-band dielectric disk antenna

Abstract

The simulation and measurement results relative to the radiation characteristics of dielectric disk antennas with the axial-symmetric excitation are presented. Based on the results of computational modeling the compact dielectric disk antenna with the −10dB impedance bandwidth Δf=4.1GHz and mono-beam radiation pattern is manufactured and tested. The choice of relation between the dielectric disk radius and substrate height allows for designing a set of antennas operating from f=5GHz to 21.77GHz.
