Hybrid Fabric Wearable Antenna Design and Evaluation for High Speed 5G Applications

Design of a textile antenna operating at multi frequency band with microstrip patched is proposed in this paper significant for applications operating at 5G and LTE band. The design involves a U-Shaped slot, a rectangular shaped microstrip patched and two annular concentric slots. Current distribution in the surface undergoes modification by introducing three meanders sleeved in the ground plane leading to improvement of bandwidth. Coral Reefs Optimization integrated with Substrate Layer (CRO-SL) algorithm is utilized for optimizing the meanders, the dual circular slots and the U-shaped slot. The multi optimization method is utilized for this meta-heuristic population based approach which is a type of ensemble algorithm which considers various search operators in the same algorithm. In this work, a robust textile antenna is optimized using CRO-SL algorithm which operates at the frequency band of both LTE and 5G range. The process of optimization precedes by a fitness function guiding the CRO-SL, generated by means of antenna simulation through hybridizing with CST simulation software such that electromagnetic analysis is performed in the high frequency range.
