This paper presents a brief account of the findings on a switched parasitic dielectric resonator antenna (DRA) array excited in a higher-order mode. The scanning phase can be changed by using switching technique and capacitor loading at the parasitic element. The driven DR and parasitic DRs have a dielectric constant of 10 and were fed by a microstrip slot aperture. The impact of mutual coupling on...
The performance analysis of reflectarray resonant elements based on Finite Integral Method is presented in this work for 5G antenna systems. Reflection loss, bandwidth and linear phase range of square and circular resonant element configurations have been investigated at 15 GHz and 20 GHz frequencies. Periodic reflectarrays consisting of 5×5 elements have been designed at 20 GHz for both elements...
