Abstract
5G stands for fifth-generation mobile network. 20 GB/s is the maximum speed of 5G, which is also more efficient and has ultra-low latency. We have built and simulated triangular-shaped compact 5G wideband microstrip antennas for body-centric networks (BCN) operating on 28 GHz. A microstrip antenna is made out of a very thin metallic strip placed between a ground plane and a dielectric material. The radiating element and feed lines are etched onto the dielectric material using photoetching. The design of the antenna consists of a triangular radiator patch. This antenna is created and modeled with the aid of computer simulation technology (CST), which is very popular for antenna design. This antenna is designed to operate at 28 GHz. The desired 28 GHz frequency response is achieved by careful parametric modeling. The materials of the triangular antenna of the patch and feedline are copper (annealed), and the substrate and ground are made up of FR-4 (loss-free). The maximum achieved gain at the desired resonance frequency of the triangular antenna in free space is 5.91 dBi, and the total efficiency is 80.24%. On the other hand, the maximum gain in on-body simulation is 8.701 dBi at 4mm body distance, and the highest total efficiency found is 72.57% at 8mm body distance. The value of VSWR in free space is 1.48. In addition, 1.44 is the lowest achieved VSWR value in 4mm and 6mm body distance in on-body simulation. The values we achieved are close enough to the targeted values.
