Computer-Aided Design of Superconducting Equilateral Triangular Patch on Anisotropic Substrates

“…Isotropic substrates may as well exhibit anisotropy at high frequencies [18]. In earlier studies, we demonstrate that the optical properties of anisotropic substrate can dynamically exhibit wider bandwidth characteristic with several resonant frequencies [15][16][17][18][19]. Therefore, its precise description, including the effect of anisotropy on the substrate, is important for computer-aided design of microstrip antennas.…”

“…Several useful techniques have been reported to broaden bandwidth of microstrip antennas (MSAs). Firstly, the most popular way to enhance bandwidth is the use of an electrically thick substrate, low dielectric constant substrate, and multilayered stacked geometry [1,15,16]. However, all of the above techniques increase the size or volume of the antenna.…”

“…However, all of the above techniques increase the size or volume of the antenna. Secondly, cutting slots inside the patch [16] and employing aperture coupled feeding network technique is another way to increasing the bandwidth of microstrip antennas. As compared to simpler coupled designs, slot cut in MSAs is relatively complex in design [7].…”

“…Therefore, its precise description, including the effect of anisotropy on the substrate, is important for computer-aided design of microstrip antennas. Several methods have been reported to study the properties of resonance and radiation patterns of microstrip patch antennas which utilize various techniques, and generally these techniques are classified as either approximate or full-wave methods [11][12][13][14][15][16]. Approximate techniques are usually developed for structures of a simple geometry, and furthermore, because they make the problem easy to understand by using certain assumptions, they can be relatively reliable and accurate under relevant conditions [16].…”

The spectral domain approach, full-wave analysis methods, and also commercially available simulation software can be used for the analysis of characteristics of patch antennas in multilayer substrates and for various structures and complex geometry [17][18][19].…”
