A Compact Design of Planar Array Antenna with Fractal Elements for Future Generation Applications
Keywords:
5G wireless communications, fractal antenna, patch antenna, planar phased arrayAbstract
In this paper, a planar phased array fractal antenna for the future fifth generation (5G) applications is presented. The proposed array antenna is designed to operate at 22 GHz. 64 patch antenna elements with coaxial-probe feeds have been used for the proposed design. The antenna elements are based on Vicsek fractal geometry where the third iteration patches operate over a wide bandwidth and contribute to improve the efficiency and realized gain performance. The designed planar array has more than 22 dB realized gain and -0.3 dB total efficiency when its beam is tilted to 0° elevation. The antenna configuration is simple, easy to fabricate and can be integrated into 5G devices. Simulated and measured results are presented to validate the usefulness of the proposed phased array antenna for 5G applications.
