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.
