Investigation of Flame‐Retarded Epoxy Resin Fiberglass Composite Material‐Based Coplanar Waveguide Patch Antennas

Abstract This article examines coplanar waveguide (CPW)‐fed flame‐retarded FR‐4 woven fiberglass laminated antenna design methods and how to optimize electrical parameters, including impedance bandwidth, return loss, and gain. In this article, a comparative examination of different design strategies that can be employed in the CPW‐fed antenna, including adding stubs, slots, notch bands, metamaterials, frequency selective surfaces (FSS), and CPW‐fed multiple‐input‐multiple‐output (MIMO) antennas, is investigated. In the proposed work, meander line effects are explored on the electrical parameters of CPW‐fed FR‐4 woven fiberglass‐laminate antennas. These design methods and their effects on antenna electrical parameters are also examined.
