Objective: To design and fabricate a compact fractal antenna with high Bandwidth Ratio (BR) and Bandwidth Dimension Ratio (BDR) for Super-Wideband (SWB) and upcoming wireless communication applications. Methods: High Frequency Structure Simulator (HFSS) is used for all the required simulations regarding antenna prototype design and optimization. The proposed antenna consists of nested square fractal in a circular ring and with a rounded corner notch loaded partial ground, which is designed and fabricated on 1 mm thick FR4 substrate. Findings: The final results evince that proposed antenna has an operating bandwidth of 36.5 GHz (2.37-38.95 GHz), with a reflection coefficient (S 11 ) less than -10 dB. It has a maximum gain of 13.4 dBi, BDR of 3498, and BR of 16.4:1. It has an Electrical dimension of 0.22 × 0.23 λ 2 . The proposed antenna's resonating and radiation characteristics have been validated experimentally. Simulated and experimentally measured results are in good agreement with each other. Novelty: The key benefits of the proposed antenna are small electrical dimensions, large bandwidth, and a high BDR. The proposed antenna is suitable for numerous wireless applications such as WLAN, WiMAX, Wi-Fi, 5G communication in sub-6Ghz band as well as in mm Wave frequency band, and S, C, X, Ku, and Ka bands applications.

SummaryA band‐notched super wideband (SWB) planar monopole antenna with improved notch characteristics is proposed in this article. A hexagonal SWB antenna operating in the frequency range from 3.04 to 36 GHz is initially designed on Arlon substrate. The hexagonal patch is then loaded with optimum sized U‐shaped slot to eliminate WLAN band (5.15–5.85 GHz). The notch band's characteristics are further improved by incorporating a frequency selective surface (FSS) of a square array at a specific distance below the antenna to introduce a phase delay of 180° between the back radiation reflected by the FSS with the front radiation at the notched frequency. Improvement of notch band gain, efficiency, and antenna front‐to‐back ratio (FBR) are studied. The antenna without embedding an FSS exhibits working spectrum from 3.1 to 33.6 GHz with notch frequency gain of −2.6 dBi and efficiency 53%. The inclusion of an FSS layer at 25.2 mm behind the antenna results in notch frequency gain of −7.6 dBi with an efficiency of 23%. FBR improvement of about 16 dB is achieved at 8 GHz, and FBR is reduced by about 5 dB at the notch frequency. 169% fractional bandwidth with bandwidth dimension ratio (BDR) of 1622 is achieved in this proposed FSS integrated antenna. The inclusion of FSS to improve the band elimination performance represents the novelty of this proposal. The data are validated by electromagnetic simulation and physical measurement techniques.
