Bandwidth Enhancement of Microstrip Antenna by Incorporation Koch Fractal Defected Ground Structure for WLAN/Wi-Fi Applications
This paper investigates the bandwidth enhancement of a microstrip patch antenna (MPA) by incorporating a Koch fractal-based Defected Ground Structure (DGS). The antenna features a rectangular patch of 29.4 × 38 mm and a ground plane of 60 × 60 mm, designed on an FR4 epoxy substrate with a dielectric constant of 4.4 and a substrate height of 1.6 mm. The operating frequency is 2.4 GHz chiefly used for wireless LAN (WLAN) and Wi-Fi applications. The Koch fractal, with its self-similar structure involves recursive iterations that enhance the antenna’s performance improving the antenna's bandwidth. The design is simulated using HFSS, showing significant performance improvement in terms of return loss and bandwidth.
