Abstract
The analysis and new results of the resonance frequency and radiation pattern of antennas array, for glass fiber FR-4 substrate using superconductor and copper patch, are presented. The linear superconducting rectangular antennas array uses the new materials SnBaCaCuOy at temperature of 160 K with conductivity equal 1.5 x 10(5) S/m. The concise full wave Transverse Transmission Line (TTL) method is used in the analysis and to obtain some results. The HFSS is also used and new results for the reflection coefficient (S11), return loss as functions of the resonant frequency, and pattern radiation of antennas array, are presented.
Highlights
The discovery of new superconducting materials has attracted an enormous interest in the scientific community world, because of its technological potential in terms of devices applications as antennas, sensors, detectors
The black curve shown the results using FR-4 substrate with r = 4.4, length = 60.0 mm, width = 50.0 mm, substrate thickness = 1.48 mm with superconductor patch SnBaCaCuOy, while the red curve shown the results using copper patch, with the same FR-4 substrate
It was observed that the resonant frequency of the copper patch had a reduction of 1.73% compared to the resonance frequency of the superconductor patch, equivalent to a decrement in the 160 MHz operating frequency
Summary
The discovery of new superconducting materials has attracted an enormous interest in the scientific community world, because of its technological potential in terms of devices applications as antennas, sensors, detectors. Ochsenfeld, which reports the perfect diamagnetism, which means that lines of magnetic flux are completely expelled from the superconductor and there is a force that repels the superconducting away from magnetic fields. This phenomenon became known as the Meissner effect [1,2,3]. The HFSS is used and new results for the reflection coefficient (S11), return loss as functions of the resonant frequency, and pattern radiation of antennas array, in 2D and 3D, are presented. The superconducting material is the characterization of chemical compounds and laboratory tests, where the analysis of the 160 K compound, dubbed Sn-3427
