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...
This paper presents a thorough investigation of the relationship between reflection loss and dynamic phase distribution performance of three different reflectarray resonant elements. The tunability characteristics of rectangular, dipole and ring elements printed on grounded non-linear dielectric anisotropic substrates have been investigated at X-band frequency range using CST computer model. A detailed...
Properties of substrate material play an important role in the design of reflectarray antenna. In this work linear and non-linear dielectric properties of substrate materials are discussed thoroughly. Rogers RT/d 5880 and K-15 nematic are used as linear and non-linear dielectric materials respectively, to design different reflectarray resonant elements in X-band frequency range. Simulated and measured...
