Design and Analysis of a Microstrip Antenna Based on Superconducting Material for Millimeter Wave Applications

Abstract

In this paper, we present a design and analysis of microstrip antenna based on superconducting material for millimeter wave applications. The proposed antenna is simulated using electromagnetic microwave studio computer simulator CST. The structure is made by two materials: the yttrium barium copper oxide (YBCO) thin film superconductor material as the patch and silicon Si as substrate with permittivity of 11.9. The superconductor material is characterized by a conductivity of 1.62 × 10 7 S/m and critical high temperature of 89 K. The simulated results concerning the return loss show that our structure has ultra wide band over 27 to 70 GHz. Low return loss of the superconductor antenna compared with his perfect conductor counterpart is achieved. In addition, good radiation pattern characteristics are obtained in the frequency band of operation. The proposed antenna has also overall size of 3 × 3 mm 2 , which facilitate its integration in architecture of communications systems.
