“…These band rejection approaches included etching out the split-ring (SRR) and complementary split-ring resonators (CSRR), which exhibit a stop-band when excited by a time-varying axial electric field as illustrated in [27,28]. Other techniques have been considered such as introducing slots on the radiating element [26,29] and DGS in the ground plane [19,30] or using parasitic elements [31] or by combining multiple techniques [32]. In this paper, we considered notching the unwanted bands using slots introduced in the radiating patch.…”

This paper presents the design and realization of a compact printed ultra-wideband (UWB) antenna with notching characteristics for compact devices using a genetic algorithm. The antenna is capable of mitigating an adjacent sub-band ranging from 3.75 to 4.875 GHz, mainly used by many applications and standards such as WiMAX, WLAN and sub-6-GHz. The notch band functionality is achieved by etching out two symmetrical slots from the pentagonal radiating element. The simulation and measured results demonstrate that the proposed antenna overperformed compared with state-of-the-art antennas in terms of compactness with an overall size of 20 mm×15 mm×0.508 mm. Moreover, the proposed design shows a large bandwidth in the UWB region with a fractional bandwidth of 180% with respect to the center frequency of 5.25 GHz. The antenna also presents omnidirectional radiations all over the operation band and a good return loss performance.

“…The WiMAX, C, WLAN, and ITU‐8 bands may be controlled by altering the overall length of the U‐type slots. The center frequency,

f_{ni}

, of four notched bands is approximated by the half‐wavelength resonator described by Devana and Rao, 24

f_{ni = \frac{C}{2 \sqrt{{normalε}_{eff}} ((), {normalL}_{Ti})}}

ε_{eff} goodbreak= \sqrt{\frac{{normalε}_{normalr} + 1}{2}}

where

C

is the “speed of light in is free space” and

ε_{r}

is the “relative permittivity.” Here L Ti is the total length of inverted U‐type slots. Where i = 1, 2, 3, and 4.…”

“…The proposed radiator is printed on a Rogers RT5880 substrate with a size of W S × L S and thickness of 0.764 mm along with a microstrip line feed of W F ×L F as depicted in Figure 1(a). The proposed antenna consisting of notched rectangular bevels of g × h at the lower edge of a rectangular patch structure of a × i etched on top of the substrate along with a rectangular defected ground structure (RDGS) of dimension W S × L G is printed below the substrate to achieve UWB bandwidth [18]. To realize the two notched bands, the proposed UWB antenna and L-type stubs are on top and sides of the patch structure with dimensions of b × c and d × e, respectively.…”

An ultra-wideband (UWB) antenna with dual band notched characteristics verified by characteristic mode analysis (CMA) is presented. The intended UWB radiator is etched on a Rogers RT5880 substrate with a size of 29 × 35 × 0.764 mm 3 , operating over a spectrum of 2.66-14.86 GHz with a fractional bandwidth (FBW) of 139%. Dual notched bands at WiMAX (3.01-3.63 GHz) and WLAN (4.48-5.85 GHz) are achieved by embedding L-shaped stubs in the notched rectangular patch. In addition, the two notched bands of the reported antenna are verified by using characteristic mode analysis (CMA) in terms of modal significance (MS) and characteristic angle (CA). The reported antenna's simulated and tested results are well matched to obtain S 11 , VSWR, stable radiation patterns, a stable peak gain of 2.65 to 3.6 dBi, and the maximum radiation efficiency of 97.86% in frequency domain, which make the intended radiator suitable for portable UWB applications.
