Abstract
A reflectarray element controlled by varactor diode is evaluated in improving dynamic phase range and loss performance at Ku-band that will form a fundamental approach for a successful design of an antenna element in the array environments. The use of varactor diode is quite advantageous as its offers the beam scanning capability as required for reflectarray antenna but it often said as the contributor to high losses and low phase range. A combination of patch’s phase response and reflection loss in dual configurations are considered as phase and loss solution in reflectarray design. Simulated results of reflectarray element under normal incidence based on dual gaps ring patch design with varactor diode embedded across the left gap in single layer substrate executed by commercial full-wave electromagnetic software CST Microwave Studio. A dynamic phase range of 300◦ with maximum reflection loss of 0.85 dB have been demonstrated at 14.706 GHz.
