Comparative study of different feeding mechanisms on thermally stable resonator antenna

Abstract

This paper presents the comparison of the features of three dissimilar feeding methods namely co-axial probe, microstrip line and co-planer feeding for a thermally stable resonator antenna (TSRA). First, nanoparticles have been developed by using proper synthesis process and then mixed in accordance with their temperature coefficients such as to achieve thermal stability. The Nicholson-Ross-Weir conversion method has been used for the determination of microwave dielectric constant (εr) and permeability (μr). Further, a thermal stable cuboid shaped resonator antenna was developed by using this composition. Three different feeding techniques are used and their corresponding resultant characteristics are compared for this developed antenna.
