Wearable Flexible Triangular Microstrip Antenna for Sub-6 GHz 5G Applications

Abstract

In this paper, a flexible triangular patch antenna is designed, simulated, and fabricated. A textile substrate with a presumed relative permittivity of 1.6 was considered. The antenna was fabricated using denim (jean) textile as the substrate with dimensions of 30 × 34 × 0.8 mm<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> and copper tape as the conductive material, while it was designed and simulated using ANSYS HFSS, and the results were validated using CST Microwave Studio software. The textenna (textile + antenna) attained a resonance frequency of 4.30 GHz and a bandwidth from 2.74 GHz to 5.00 GHz, exhibiting superior resonance characteristics in the Sub-6 GHz range. These findings verify that the proposed antenna is highly competitive as an inexpensive, compact, and easily integrable solution for Sub-6 GHz 5G, WiMAX, and wearable applications.
