“…In this view, several single [21,22], dual [23,24], triple [25][26][27], quad [28,29], quintuple [30,31], and sextuple notch [32,33] UWB antennas have been showcased in the literature [21][22][23][24][25][26][27][28][29][30][31][32][33]. In [21], the authors have proposed a single-band notch antenna. A half-wave resonant structure in the patch is used to obtain a notch band at 5.6 GHz for band rejection of WLAN.…”

“…In this, a stub with an open end with a meandered resonator along with a defective ground structure is used to achieve a sextuple notch of 3.3-3.6 GHz, 5.1-5.3 GHz, 5.6-5.9 GHz, 7.2-7.6 GHz, 7.8-8.2 GHz, and 9.2-9.7 GHz. However, for the present paper, the analysis of the proposed design is limited to a dual-notch band of operation, and its relevance is judged based on the antenna proposed in [21][22][23][24].…”

This article presents the design and analysis of a V-shaped ultrawideband (UWB) antenna and dual-band UWB notch antenna. A rectangular slot is cut into a semicircular partial ground plane of the antenna to achieve ultrawide bandwidth. A U-shape slot is etched on a V-shaped patch that radiates, and an inverted U-shape parasitic resonator is placed beside the feedline to generate dual-band notch characteristics. The overall dimension of the proposed antenna is 28×23 mm2. The proposed UWB antenna has a gain of 9.8 dB, S11 < −10 dB, impedance bandwidth in the range of 3.4 to 12.3 GHz, response with a linear phase, group delay <1 ns, and stable radiation pattern. The UWB notch antenna shows strong rejection in the WLAN band from 5.15 to 5.8 GHz with a notch at 5.6 GHz and X band from 9.1 to 10.5 GHz with a sharp notch at 9.6 GHz, having a S11 < −10 dB impedance bandwidth ranging from 3.2 to 11.7 GHz. This antenna also exhibits a stable radiation pattern, group delay <1 ns, and linear phase response throughout the bandwidth except at the rejection frequencies.

A novel design exhibits band stop characteristics at WLAN and ITU band which include metamaterial inspired SRR structure and embedded resonant cell (ERC). The low-profile antenna has a metamaterial-inspired SRR structure and an embedded resonant cell that produce dual band notching at the WLAN frequency from 5.2 to 5.9 GHz and ITU frequency from 7.9 to 8.8 GHz. By changing the dimensions of the SRR structure and embedded resonant cell inspired by metamaterials, the rejected bands can be controlled. According to simulation results, The intended antenna has a broad impedance bandwidth extending from 3.4 GHz to 13 GHz with a VSWR of less than 2.The results of the simulation show that the low profile antenna has a steady gain over the radiating frequency range, with an optimised gain of 4.12 dBi.
