“…Several researchers have studied the effect of the air gap layer on the resonant frequency of highTc superconducting microstrip patch antenna [7,10,13,17]. To the best of our knowledge, neither any design guideline nor any experimental or theoretical results are available in the open literature to predict the characteristics of high-Tc superconducting rectangular microstrip patch with substrate-superstrate configuration.…”

“…Bandwidth of antenna can be increased by designing the antenna with dielectric cover [13], where structures with substrate-superstrate are generally employed to improve the characteristics of the resonator, especially those of the antenna [14]. Whether a superstrate over the patch is naturally formed or imposed by design may adversely affect the antenna's necessary performance characteristics such as resonant frequency, quality factor, bandwidth, radiation resistance, efficiency, and gain [15].…”

Abstract-The resonant characteristics of superconducting rectangular microstrip patch antenna with a superstrate layer are investigated using a full-wave spectral analysis in conjunction with the complex resistive boundary condition. The complex surface impedance of superconducting patch is determined using London's equation and the two-fluid model of Gorter and Casimir. Numerical results using the full-wave analysis presented here are in excellent agreement with theoretical and experimental results available in the open literature. Numerical results show that the effect of the superstrate layer on the resonant frequency and half-power bandwidth of the superconducting rectangular patch is stronger than that of the structure without superstrate layer as both the thickness and permittivity of the superstrate increase. Finally, numerical results concerning the effects of the parameters of superstrate-substrate and superconducting patch on the antenna performance are also presented and discussed.

“…The superconducting film is characterized by a critical temperature T c , a zero-temperature penetration depth λ 0 , and a normal state conductivity σ n . Following a mathematical reasoning similar to that shown in [13] for obtaining a relation among the surface electric field at the plane of the superconducting patch and the surface current on the patch in the spectral domain given by …”

“…Therefore, an algorithm for the computation of the resonant frequencies of microstrip patches should be able to account for multilayered substrate effects. Theoretical researches on the effect of dielectric superstrate on the resonant frequency of a perfectly conducting patch are abundant [13]; however, there is no theoretical report on the effect of superstrate on the resonance of a high T c superconducting rectangular microstrip antenna. This paper presents a rigorous full-wave analysis of high T c superconducting rectangular microstrip patch in a substrate-superstrate configuration.…”

The effect of a protecting dielectric superstrate on the resonance of a high T c superconducting microstrip patch is investigated. The analysis approach is based on the spectraldomain method of moments in conjunction with the complex resistive boundary condition. The complex surface impedance of the superconducting thin film is determined using London's equation and the two-fluid model of Gorter and Casimir. Numerical results show that the resonant frequency of the high T c superconducting rectangular patch decreases monotonically with increasing superstrate thickness, the decrease being greater for high permittivity loading.

Conventional rectangular microstrip-fed patch antennas are initially investigated numerically within the frequency band 2.0 to 2.8 GHz for Wi-Fi applications. In order to enhance the input parameters of the underlying antennas, three prototypes are designed. A split is diagonally loaded on a conventional radiating patch to achieve a duo triangle-shaped microstrip-fed patch antenna in the first step. The conducting ground plane of the conventional and the duo triangle-shaped patches is modified to design the microstrip-fed monopole and duo triangle-shaped monopole antennas in the second and third steps, respectively, within the frequency band of 2.0 to 7.0 GHz. Concepts of voltage and current waves as well as classical electrostatics approach solutions are used to, respectively, investigate the return loss bandwidth and the electric field radiation pattern of the proposed antennas. Numerical simulations show some relevant antenna performances such as a triple-band, a −10-dB return loss bandwidth of 29%, a gain of 7.5 dB, and a calculated half power beam width of 120°in E-plane.KEYWORDS duo triangle-shaped, input impedance, radiated field pattern, rectangular microstrip-fed patch antenna, split-patch/monopole antennas
