“…In [1,2], the cavity model has been used to analyze cylindrical-rectangular patch antennas, printed on a dielectric substrate, while in [3,4] the method of moments (MoM) has been used for analyzing them. Similar antennas printed on a chiral substrate have been analyzed in [5] using the MoM and the dyadic Green's functions derived for the problem with reference to [6,7].…”

Abstract-Radiation from a superstrate loaded cylindrical-rectangular microstrip patch antenna with an air gap between the substrate and the superstrate, is analyzed using the full-wave approach and the electric surface current model. Results are presented in the form of normalized radiation patterns for various thicknesses of the air gap and also for superstrates made of lossy dielectric material, to show the effects of these on the radiation from the antenna. Both axial and azimuthal current elements are considered.

“…Though the models used in analyzing microstrip structures have been widely accepted, the effect of curvature on dielectric constant and antenna performance has not been studied in detail. Low profile, low weight, low cost and its ability of conforming to curve surfaces [1], conformal microstrip structures have also witnessed enormous growth in the last few years. Applications of microstrip structures include Unmanned Aerial Vehicle (UAV), planes, rocket, radars and communication industry [2].…”

Curvature has a great effect on fringing field of a microstrip antenna and consequently fringing field affects effective dielectric constant and then all antenna parameters. A new mathematical model for input impedance, return loss and voltage standing wave ratio is introduced in this paper. These parameters are given for TM 01 mode and using two different substrate materials K-6098 Teflon/Glass and Epsilam-10 Ceramic-Filled Teflon materials.

This study presents a full‐wave solution for arrays of cylindrical‐rectangular microstrip antennas, with superstrate. It uses the method of moments (MoM), with full‐domain basis functions. The same set of functions is used as testing‐functions resulting in a Galerkin procedure. A numerical procedure is presented allowing an efficient and numerically stable evaluation of the elements of the MoM linear system. Results for input impedance are compared to those using HFSS for a flush‐mounted geometry. Results for radiation pattern, mutual impedance, and coupling coefficient S12 are also presented. And the effects of the superstrate on those parameters are evaluated.
