A miniaturized super-wideband (SWB) monopole antenna is presented in this work. Electrical dimension of the presented antenna is 0.239λ Â 0.239λ Â 0.0147λ, where λ indicates the wavelength corresponding to the lowest operating frequency. Presented antenna displays single À10 dB operating band from 2.75 to 28 GHz with 164% percentage bandwidth and bandwidth ratio of more than 10:1. The proposed SWB antenna exhibits a large bandwidth dimension ratio (BDR) of 2871 with realized gain of 4.80 dBi. Radiating patch of the proposed antenna is designed by modifying conventional rectangular patch by loading a matching stepwise structure. Further, in order to achieve SWB characteristics, the ground plane is reduced with a loaded rectangular notch for better impedance matching. The designed antenna has the advantages of simple planar miniaturized structure, acceptable gain, and wide bandwidth to support various objectives in modern wireless communication. To boost the maximum gain further over the entire frequency band, the proposed antenna is combined with the proposed frequency selective surface (FSS) which acts as a partially reflector surface. The antenna is placed over 4 Â 4 FSS at suitable distance without hampering the obtained bandwidth of the antenna. FSS combined antenna structure, having the physical volume of 56 mm Â 56 mm Â 26.2 mm, exhibits realized gain of 9.3 dBi which is suitable for long range communication. CST MWS (Microwave studio) for simulation results of the suggested antenna and appropriate Microwave Test bench is used to verify the same.

“…To embed the benefits of SWB technology in practical wireless applications, multidimensional research has been undertaken for diverse antenna configurations. For the purpose of achieving wider bandwidth, many different kinds of bandwidth enhancement techniques, such as modification in the ground plane and the patch [ 2 , 3 , 4 , 5 , 6 , 7 , 8 ] along with a diverse range of feeding techniques, such as microstrip tapered feedline [ 9 , 10 , 11 , 12 , 13 ] and Coplanar Waveguide (CPW) feed [ 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 ], have been proposed by antenna designers. To miniaturize the dimension of antenna without impacting the impedance bandwidth, self-similarity structures, such as fractal geometry [ 22 , 23 , 24 , 25 , 26 , 27 ], have been envisioned in the literature.…”

“…A CPW-fed propeller-structured monopole antenna for SWB application is demonstrated to provide a good impedance bandwidth from 3 to 35 GHz; however, it suffers from a lower BDR value (809) due to its large electrical dimensions [ 14 ]. In [ 15 ], a CPW-fed antenna with inverted triangular shaped patch is designed to exploit across the frequency range from 3.06 to 35 GHz. However, the gain of the proposed antenna structures has not been reported.…”

In this article, a compact concentric structured monopole patch antenna for super wideband (SWB) application is proposed and investigated. The essential characteristics of the designed antenna are: (i) to attain super-wide bandwidth characteristics, the proposed antenna is emerged from a traditional circular monopole antenna and has obtained an impedance bandwidth of 38.9:1 (ii) another important characteristic of the presented antenna is its larger bandwidth dimension ratio (BDR) value of 6596 that is accomplished by augmenting the electrical length of the patch. The electrical dimension of the proposed antenna is 0.18λ×0.16λ (λ corresponds to the lower end operating frequency). The designed antenna achieves a frequency range from 1.22 to 47.5 GHz with a fractional bandwidth of 190% and exhibiting S11 < −10 dB in simulation. For validating the simulated outcomes, the antenna model is fabricated and measured. Good conformity is established between measured and simulated results. Measured frequency ranges from 1.25 to 40 GHz with a fractional bandwidth of 188%, BDR of 6523 and S11 < −10 dB. Even though the presented antenna operates properly over the frequency range from 1.22 to 47.5 GHz, the results of the experiment are measured till 40 GHz because of the high-frequency constraint of the existing Vector Network Analyzer (VNA). The designed SWB antenna has the benefit of good gain, concise dimension, and wide bandwidth above the formerly reported antenna structures. Simulated gain varies from 0.5 to 10.3 dBi and measured gain varies from 0.2 to 9.7 dBi. Frequency domain, as well as time-domain characterization, has been realized to guide the relevance of the proposed antenna in SWB wireless applications. Furthermore, an equivalent circuit model of the proposed antenna is developed, and the response of the circuit is obtained. The presented antenna can be employed in L, S, C, X, Ka, K, Ku, and Q band wireless communication systems.
