Abstract :
An analysis and design for a high-Tc superconducting planar antenna, particularly a microstrip patch antenna, is presented in this work. The concise Transverse Transmission Line (TTL) method in the Fourier Transform Domain (FTD) along with the Transmission Line Model are applied. However, the analysis can be extended to other planar structures using materials with losses, such as semiconductor, or lossless dielectric substrates. Since the TTL is a full wave method and very much suitable for microwave and millimeter-wave components study, it gives an accurate effective dielectric constant which contributes definitively to obtain all others antenna parameters with high precision such as length, efficiency, bandwidth, quality factor and radiation patterns
