“…The fractal geometry in planar antenna structures has been recognized as one of the most important techniques to improve the bandwidth. Fractal is a geometric shape consisting of self-similarity of the same structure and space-filling, which results in bandwidth enhancement and multiband, i.e., several resonant bands, and in combination, it can form an SWB antenna [24,25]. The modified circular monopole antenna shown in Fig.…”

This paper presents the design of a Super Wideband (SWB) antenna with enhanced bandwidth for microwave applications with a detailed parametric study of the methods used to enhance the bandwidth of the conventional antenna. The proposed SWB antenna has emerged from a traditional circular monopole antenna by experimenting with an inscribed fractal structure with a tapered feed line and partial ground plane with blended corners and achieved a super wideband frequency range from 2.31 GHz to 105.5 GHz with a fractional bandwidth of 192.1% and a Bandwidth Dimension Ratio (BDR) of 2154.88. The antenna has a relatively small electrical dimension, i.e., 0.33λ 0 × 0.27λ 0 , where λ 0 corresponds to the lower-end operating frequency and exhibits good gain and efficiency characteristics. In order to observe the signal correlation of the proposed antenna, the time domain analysis using similar antennas in face-to-face and side-to-side scenarios has been performed using the EM simulation tool CST-STUDIO. The simulated gain varies from 1.28 to 9.35 dBi. The proposed antenna can be used for S, C, X, Ka, Ku, V, and W bands for microwave and millimetre wave applications. The simulated and measured results of the proposed antenna exhibit a good agreement.

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.

“…A staircase fractal curve was applied on a microstrip line which fed a truncated corner square patch antenna. This configuration was proposed by the authors in [10], where the band 0.1GHz -30 GHz was continuously covered, with a size area of 60 × 60 mm 2 . In [11], the authors presented a geometrical structure that incorporated a combination of the Peano-Gosper, Koch and Minkowski fractal curves.…”

This paper presents two different antenna modules at two different bands with a compact size structure that is used for both of mm-Wave and microwave bands, with the objective of keeping the size as minimum as possible. The presented structure consists of two integrated modules with overall dimensions of 24 × 15 × 0.787 mm 3 and is implemented on a Rogers RT5880 substrate. The first module is designed to resonate at 25.75 GHz with bandwidth of 4.15 GHz. The length of this module is taken as a constraint in designing the second module, which is the microwave one. This module is designed to have resonance frequency of 5.45 GHz with bandwidth of 1.12 GHz. The two modules are etched on the same substrate in an integrated fashion to give the required structure with two separate feeds and a separation gap between them in the ground plane. The proposed antenna structure is simulated using the CST-MW studio simulator, where it is found that for the mm-Wave module, the band's gain is 5.58 dBi and the efficiency is 0.87 at 25.75 GHz. As for the microwave module, the gain is 2.45 dBi and the efficiency is 0.77 at 5.45 GHz. The proposed structure is implemented practically and the relevant measures agree with the simulated ones. A comparison of the proposed structure with other designs available in literature shows that it exhibits the minimum size among them, while keeping the other parameter values of comparable orders. The proposed structure is suitable for being used in 5G applications where both of the microwave and millimeter-wave bands are utilized. Microstrip antenna,, mm-Wave fifth generation (5G), DGS.
