This paper presents a full-wave solution for cavity-backed annular conical antennas. The analysis is based on equivalence principle and Method of Moments for modeling the equivalent surface magnetic currents. Numerical results for input impedance and gain patterns are shown.
An efficient procedure for the pre-design of circumferential circularly-polarized cylindrical microstrip arrays, based on the electric surface current model, is the focus of this work. Its major achievement is cutting the time to pre-design the patch dimensions down to less than one-tenth of what it takes in a 3D electromagnetic simulator, such as the HFSS, running on high-performance workstations...
This work (this work was partially supported by FACEPE and CNPq) perform a full-wave analysis, using method of moments, to determine the mutual impedances of spherical microstrip patches. The patches are allowed a more general shape, following the spherical coordinates, as shown in Fig. 1. The effect of moving the patches (keeping the average widths) toward the z-axis will be discussed on both input...
