Paper Abstract

In this paper, we analyze electrical small HTS (High-Tc Superconductors) patch antennas using the modified spectral domain moment method (SDMM). This paper presents the numerical results for a 2.8 GHz HTS patch antenna with 12 mm length and 1.5 mm width on the grounded dielectric substrate with thickness d equals 0.5 mm, (epsilon) r equals 25 and tan (delta) equals 0. As the result, we can see that efficiency of the HTS patch is improved, for example, 3.8 times at T equals 0(K) and 2.9 times at T equals 77(K) improvement are obtained from our analysis. We also show that the resonance frequency of the HTS patch is shifted as temperature is changing.
