Design of a Planar Multi-band Antenna Array based on Split Ring Resonator for WiMAX and 5G Sub-6GHz Applications

In this paper, a novel technique based on rectangular shaped split ring resonators (SRRs) is used to examine a new multiband antenna array design. The analysis of simulation results is shown and described in this article. The suggested antenna radiator is mounted on a low cost FR4 substrate having an overall area of 154  70 mm 2 . The proposed SRRs based array antenna offers triple band resonances with high gain characteristics. The resonant frequencies, return loss, and radiation patterns are calculated concurrently using a number of simulation results that support the applicability of the created model. An electromagnetic solution based on MOM, included into ADS is used for the simulation. The full N77/N78/N79 spectrum is covered by the multiband array antenna which is validated with S 11  –10 dB for three operating frequency bands at 3.5 GHz, 4 GHz, and 4.22 GHz with high gains of 6.4, 6.8, and 7.25 dBi, respectively. It supports LTE, WiMAX, and WLAN wireless network systems, as well as the 5G spectrum operating below 6 GHz. The investigated antenna exhibits distinguishing qualities like a planar profile, a small foot-print, symmetrized radiation behavior, and a good gain. The investigated multiband antenna can be of choice as a promising candidate to be used in modern wireless communication services within microwave S-band under sub-6 GHz spectrum.
