Design and Simulations of a Superconducting Microstrip Antenna with a Square-Shaped Split ring Resonator (SRR) Structure at 28GHz.

الملخص

In this research, we design and analyze a smart antenna that uses superconducting material technology by integrating the discrete ring resonator (SRR) structure into a Microstrip Patch antenna at a frequency of 28GHz, as it aims to enhance its performance in terms of gain, direction, and radiation efficiency, which is extremely important, especially in generation applications. Fifth for communications, niobium (Nb) was used as a superconducting material. It was an RT5880 substrate material with a height of 0.787 mm and a dielectric constant r 2.2. Through simulations carried out using CST Microwave Studio, the results showed significant improvements in the electromagnetic properties of the designed antenna, where the reflection value reached S11 = -3.82dB, which is close to zero, and the gain reached 40dB, the permittivity -7.260F/m, and the permeability 0.00157 H/m. Comparing the results, it was found that the frequency of the material used had a significant effect in increasing the damage.
