“…Due to signal distortion, transmitter and receiver pulses are not the same, but the receiver antenna must recognize the pulses sent by the transmitter antenna. Thus, time domain analysis plays an important role in finding the signal distortion [12]. In the fidelity factor, the difference between Tx and Rx pulses can be investigated using the arrangement shown in Fig.…”

“…[11] describes a partially segmented circular monopole antenna with a notched elliptical partial ground plane which covers the frequency range from 0.96 GHz to 10.9 GHz with the percentage bandwidth of 167.22 with a low peak gain of 4 dBi for LTE2600, Wi-Fi, WLAN, and UWB applications. [12] proposes a skull shaped structure with a slotted rectangular partial ground plane design with a fractional bandwidth of 160.66% ranging from 3 GHz to 27.5 GHz and a peak gain of 6.3 dBi. In [13], a quasi-square with proper sizes and angles on the lower edges of the patch and ground plane with two circular slots is presented, which is a characteristic for SWB applications.…”

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.

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.

A novel compact triple elliptical monopole antenna has been designed, analyzed and fabricated for super wideband applications. To enhance the impedance bandwidth, the author proposed a monopole antenna with a triple elliptical patch excited by a 50Ω triangular tapered microstrip feedline. Further improvement is achieved by optimally modifying the Defected Ground Structure (DGS) of the antenna. The proposed patch structure is mounted on a Roger's RT-Duroid 5880 substrate (ϵ r = 2.2, tan δ = 0.0009) and has compact physical dimensions of 27 mm × 29.5 mm. The fabricated antenna covers the frequency band from 1.91 GHz to 43.5 GHz for S 11 ≤ -10 dB with a fractional bandwidth of >183.17% and has a ratio bandwidth of 22.77:1. This extended bandwidth coverage permits the antenna to operate for wide range of application including 5G and Internet of Things (IoT). The proposed antenna has a very Bandwidth Dimension Ratio (BDR) of 5761.87 which makes it the best candidate for superwideband antenna. Far field measurements disclose an omnidirectional radiation pattern across the frequency of operation. Further, the farfield Radar Cross Section (RCS) is analyzed through simulation and it is to be noted that relatively low values are obtained through out the frequency of operation. In addition, the compactness of the proposed antenna is theoretically verified with the aid of fundamental dimension limit theorem.INDEX TERMS 5G mobile communication, Bandwidth Dimension Ratio (BDR), Fundamental dimension limit theorem, Internet of Things (IoT), Monopole superwideband antenna, Tapered feed
