Design of Reflectarray Antenna with Ring-Loaded Patches for 5G Applications
5G technology is a new wireless communication system that supports a high data transfer rate with wide bandwidths. One type of antenna that can support these needs is the reflectarray antenna. Reflectarray antennas are designed for adjusting the phase of electromagnetic waves by their array elements to obtain higher gain. This study aims to design a reflectarray with 196 ring-loaded elements in a 14 × 14 array that works at 28 GHz. Simulation and fabrication used a Koch patch model with zeroth iteration as a feed antenna resulting in a gain of 6.59 dBi.
