Abstract
A dual-band antenna array has been reported in this paper working in the fundamental mode of TM11 resonance for 5G communication. Rogers Rt/Duroid 5880 as dielectric substrate having a height of 0.508 mm has been chosen for the proposed antenna. A single element ring patch antenna has been developed by etching circular slots at different angles i.e. 0°, 90°, and 180° making it perturbed which resonates at 28 GHz providing an impedance bandwidth of 4% by exciting two resonant modes making it novel. Further, to cultivate the gain, a four-element antenna array is evolved by utilizing series-feed network due to which the flux linkage of the radiating element combines with the conductive behaviour of the feed network resulting an extra resonance at 36 GHz providing reflection coefficient of more than –20 dB at both resonating frequencies. By constructing an array, the antenna gain gets doubled along with a 1% increase in impedance bandwidth at 28 GHz. By considering the various electromagnetic parameters, a detailed analysis has been done using CST MW studio ver.2018. Further, to authenticate the result of the reported antenna array, the antenna has been fabricated as well as tested using VNA which shows close resemblance with simulated antenna characteristics.
