- Abstract
In this article, an antenna array with suppressed side lobe level (SLL) is proposed for a 5G mm-wave base station application by employing a circular complementary split ring resonator (CCSRR) and amplitude tapering technique. The single, double, and hybrid CCSRRs are etched on the ground plane of the array to minimize the side-lobe power. The proposed technique suppresses pre-main beam power level and post-main beam power level by an amount of 20.08 dB and 27.28 dB, respectively. Further, a typical Dolph–Chebyscheff weighted low side lobe level array is compared with the suggested CCSRRs couplets loading. The presented module is fabricated and experimentally validated and it has a better agreement between the simulated and measured response. The presented array module has a low profile and it is very simple to integrate with other RF circuits located on the PCB board. In addition, the proposed array has wider impedance bandwidth with a low side lobe power level than the other CCSRR arrangement. Among the three configurations, hybrid CCSRR has wider beam width, enhanced gain and improved side-lobe suppression than all other CCSRR arrangement. Thus, the hybrid CCSRR configuration is a good candidate to employ 5G mm-wave indoor applications, 5G mm-wave mobile base station, Ka-band based medium distance modern wireless communication.
