Abstract
This article presents the design, fabrication, and measurements of an offset edge-fed hybrid fractal antenna for sub-6GHz and S-band applications. The antenna comprises a compressed partial ground structure and the hybrid fractal patch of the antenna is developed from a rectangular patch by subtracting an anti-symmetric mirror combination of half Koch and Minikowski curves. The antenna is designed using an HFSS electromagnetic simulator at a frequency of 3.3GHz. The lowest reflection coefficients <-10dB fractional bandwidth at resonant frequencies are -27.87dB, and -20.60dB with a peak gain of 3.90 dBi and maximum radiation efficiency of 84.50% at 3.3GHz. The prototype model of the antenna fabricated on an FR-4 substrate exhibits dual bands (2.23GHz to 3.80GHz), and (4.11GHz to 4.35GHz). The antenna is resonating at frequencies of 3.3GHz, and 4.3GHz respectively. Therefore, the designed antenna is most suitable for Bluetooth, Wi-Fi, and ISM band (2.45GHz), WLAN(3.65–3.70 GHz) (802.11b/g) (2.4-2.483GHz), Wi-Max (2.3GHz, 3.4–3.6 GHz), LTE (3.2–3.3 GHz), n77(3.7GHz), n78(3.3–3.67 GHz), n40(2.3GHz), and S-band (2.25-3.85GHz) C-band(4.11-4.15GHz, 4.24-4.35GHz) applications.
