Spectral-domain analysis of multilayer cylindrical–rectangular microstrip antennas

Efficient CAD Model to Analysis of High Tc Superconducting Circular Microstrip Antenna on Anisotropic Substrates

“…The antenna parameters for this study are h = 1.27 mm. The computed resonant frequency in Verma [14] for various anisotropic substrates is also shown to agree very well with the values computed using cavity model (6)(7)(8)(9). The results of this comparison indicate that the present model shows excellent agreements with those of Verma [14] for all values of patch radius.…”

“…Formulations of those studies are lengthy and complicated even in single substrate case. In a previously presented study [6][7][8], we have shown that circular microstrip antenna with the properly selected uniaxial anisotropic substrate is more advantageous the isotropic one by exhibiting wider bandwidth characteristic with different resonant frequencies. Several computational methods have been carried for computing the resonant characteristics of superconducting circular microstrip patch antenna by using the spectral domain analysis and other fullwave analysis methods [6,9].…”

“…In the design of microwave integrated circuit components and microstrip patch antennas, anisotropic substances have been increasingly popular. Especially the effects of uniaxial type anisotropy have also been considered in some of the later studies [5][6][7][8][9][10] due to the availability of this kind of substances such as Sapphire, Magnesium fluoride and Epsilam-10. Formulations of those studies are lengthy and complicated even in single substrate case.…”

Resonance of High Tc Superconducting Microstrip Patch in a Substrate-Superstrate Configuration

“…The successful operation of, for example, the microstrip resonators seems to suggest that basically they are poor radiators [1]. Despite this weakness microstrip antennas have received much attention in the open literatures because of their many unique and attractive properties [2]: low in profile, light in weight, compact and conformable to both planar and non-planar surfaces [3], and easy to fabricate and to be integrated with solid-state devices. At low frequencies, the analysis for this structure can be done by using either the transmission model or a cavity model.…”

Integrated Flexible Uwb/Nb Antenna Conformed on a Cylindrical Surface

“…The cylindrical antenna is a very popular type of conformal antenna and was analyzed in the past using different configurations; for example, cylindrical conformal antennas have been proposed in [17,19]. Currently, some research groups have been focused their work on the study of cylindrical antennas for UWB applications [16,20,21] and extended these concepts to other studies such as integrated UWB/NB antennas.…”
