Summary In this paper, a modified bow tie‐shaped antenna for ultra‐wideband (UWB) communication applications is presented. The anticipated antenna consists of a CPW‐fed modified bow tie‐shaped patch and two asymmetric ground planes with dual parasitic elements. Electromagnetic computation on the antenna demonstrates that the patch and grounds are strongly linked, and the designed antenna can exhibit multiple resonances which overlap to reveal the UWB working spectrum. Experimental verification of the presented antenna shows that the antenna achieved a working band of 3.2–11.0 GHz, with a fractional bandwidth of 109.9%. The antenna also attained a peak gain of 4.32 dBi at 7.3 GHz and peak efficiency of 87.3% at 6.8 GHz and reveals excellent time‐domain behavior and omnidirectional radiation patterns throughout the operating band. A small‐size, large operating band, high gain and efficiency, high fidelity factor, omnidirectional radiation patterns, and very small group delay make the antenna ideal for portable communication devices in the UWB band.

“…Contrary to the antenna reported in Ref. 33 , in this design, one inverted L-shaped parasitic element with an area of ( t 2 × L 2 + W 2 × t 3 ) is placed inside the inverted U-shaped ground. This parasitic element and lower end of the patch help the antenna to achieve the higher X-band.…”

A miniature planar antenna is a vital component of any portable wireless communication device. The antenna in portable devices should provide wide/multiple operating bands to cover a good number of narrowband services as a multi-band antenna not only reduces the number of antennas but also lessens the system complexity, cost, and device size. To operate over S-, C-, WiMAX, WLAN, UWB, and X-communication bands, in this paper, a dual-band CPW-fed antenna is presented. The anticipated antenna is made up of a vertical bow-tie-shaped patch and two asymmetric ground planes and etched on the same side of the single-sided standard substrate material. To generate two distinct operating bands, an inverted L-shaped parasitic element is inserted within the modified U-shaped coplanar ground plane. The antenna achieved dual operating bands of 3.24–8.29 GHz and 9.12–11.25 GHz in measurement which helps the proposed antenna to cover S-, C-, WiMAX, WLAN, 4G LTE, 5G sub-6 GHz, UWB, and X-communication bands. In the two operating bands, the antenna realized a peak gain of 4.33 dBi, and 4.80 dBi, the maximum radiation efficiency of 86.6%, and 72.6%, and exhibits symmetric radiation patterns. In the operating bands, the antenna also exhibits good time-domain behavior which helps it to transmit the signal with minimum distortion.

“…SWB technology provides greater bandwidth and higher data rate, which can also be utilised to broadcast voice, video, and data at a faster rate. This technology is currently used in civil and military ranging and monitoring systems, and also used in Multichannel Multipoint Distribution Service (MMDS), WLAN, unlicensed UWB, vehicular radar, 5G, wireless network applications, satellite communication, microwave, and millimetre wave applications [5][6][7][8][9], and hence compressive works have been published on super wideband antennas.…”

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.
