Abstract

could be duplicated by limiting the PMM current distribution to a single sinusoidal mode. This was equivalent to the current distribution shown in Figure 2 of the paper. Figures 6 and 7 show the comparison between PMM with a single-mode current distribution and the analytical technique for the 0.480A element length in the 0.5A and 0.7A array lattices. Excellent agreement was obtained for these cases, as well as for the element length of 0.495A. The exact element length was used in the impi .m MATLAB routine, rather than the nominal 0.5A length used by the authors in the comparisons with HFSS.

Analysis of tightly-coupled dipole phased array antennas with metasurface superstrate

“…By developing an analytical model for the array with a metasurface superstrate, we can optimize the metasurface to get the best response. For ordinary dipole array antennas (uncoupled arrays), many works have been done 19 – 21 , and adding a metasurface superstrate above the array is investigated analytically 22 and experimentally 23 . In this paper, an analytical model is developed in order to efficiently calculate the scan impedance of the coupled arrays.…”

Analysis of Tightly-Coupled Dipole Phased Array Antennas with Metasurface Superstrate

“…By developing an analytical model for the array with a metasurface superstrate, we can optimize the metasurface to get the best response. For ordinary dipole array antennas (uncoupled arrays), many works have been done [17][18][19], and adding a metasurface superstrate above the array is investigated analytically [20] and experimentally [21].…”
