Abstract

We show for high-symmetry disk, square, or equilateral triangular thin microstrip antennas respectively obeying C∞v, C4v, and C3v point group symmetries, that the transverse magnetic electromagnetic cavity mode wave functions are restricted in form to those that are one-dimensional representations of those respective point groups. The plot of the common nodal points​ of the ten lowest-energy non-radiating two-dimensional representations of each of these three symmetries is presented. For comparison with symmetry-broken disk intrinsic Josephson junction microstrip antennas constructed from the highly anisotropic layered superconductor Bi2Sr2CaCu2O8+δ (BSCCO), we present plots of the ten lowest frequency orthonormal wave functions and of the angular distributions of the emission power. These results are compared with previous results for square and equilateral triangular thin microstrip antennas.
