Abstract:
This article investigates the design of antennas fed by coplanar waveguide (CPW) utilizing different substrate materials and techniques. The article illustrates the impact of several materials such as FR-4, Rogers, Arlon, etc on electrical properties such as impedance bandwidth (IBW), reflection coefficient (|S11|), and gain. The article also examines the effects of design approaches such as including stubs, slots, arrays, etc on antenna |S11| parameters. The resonance frequencies (fr) of the suggested antennas may be modified by manipulating the electrical dimension, the dielectric constant of the substrate materials, and their respective thicknesses. The structure of the Flame-Retardant fiberglass epoxy (FR-4) proposed antenna covers an operating frequency range of 3.3 to 10.1 GHz. It can operate at six distinct frequency bands, making it appropriate for applications including C-band (4-8 GHz), X-band (8-12 GHz), 5G (3.5-6.0 GHz), and 6G (7-20 GHz). The antenna designed and simulated using computer simulation software (CST) electromagnetic simulator.
