“…References [154,155] have presented a G-shaped monopole UWB reconfigurable antenna with a PIN diode for switching and a cup-shaped UWB reconfigurable antenna with rejection in three bands using stubs and slots with three PIN diodes for switching, respectively. In [156], the authors have proposed the usage of hexagonal SRR metamaterial cells and switches for reconfiguration. In [157], the authors present a design of a band-notched UWB reconfigurable antenna which is achieved using varactor diodes placed between the split ring slots of the CSSRs used for notching.…”

Narrowband antennas fail to radiate short pulses of nano- or picosecond length over the broader band of frequencies. Therefore, Ultrawideband (UWB) technology has gained momentum over the past couple of years as it utilizes a wide range of frequencies, typically between 3.1–10.6 GHz. UWB antennas have been utilized for various applications such as ground-penetrating radars, disaster management through detection of unexploded mines, medical diagnostics, and commercial applications ranging from USB dongles to detection of cracks in highways and bridges. In the first section of the manuscript, UWB technology is detailed with its importance for future wireless communications systems. In the next section various types of UWB antennas and their design methodology are reviewed, and their important characteristics are highlighted. In section four the concept of a UWB notch antenna is presented. Here various methods to obtain the notch, such as slots, parasitic resonators, metamaterials, and filters are discussed in detail. In addition, various types of important notch antenna design with their technical specifications, advantages, and disadvantages are presented. Finally, the need of reconfigurable UWB notch antennas is discussed in the next section. Here various insight to the design of frequency reconfigurable notch antennas is discussed and presented. Overall, this article aims to showcase the beginnings of UWB technology, the reason for the emergence of notching in specific frequency bands, and ultimately the need for reconfiguring UWB antennas along with their usage.

“…For the proposed FSA, the realized gain is −2.10 dBi at 5.6 GHz and -1.91 dBi at 7.4 GHz represents the antenna eliminates WLAN and X-band signals. Moreover, the gain varies from 2.21 to 3.55 dBi, except at notched bands over operating frequencies of FSA represents the proposed FSA gain is more stable than the reported antennas [22][23][24][25][26][27][28][29][30][31][32][33][34] in Table 3.…”

A compact flower slotted antenna (FSA) for dual band eliminated ultrawideband (UWB) integrated with Ku band applications is proposed. The basic FSA with modified ground structure is utilized for obtaining fractional bandwidth of 137% (3.45-18.45 GHz). The dual band eliminated frequencies are achieved by a via hole to eliminate 5.39 to 5.90 GHz (upper WLAN band) frequencies and by utilizing symmetrical inverted L-shaped parasitic elements to notch 7.30 to 7.75 GHz (downlink of X-band satellite communication link) frequencies. The FSA is having a compact size of 16 × 22 mm 2 printed on low cost FR-4 substrate with two band notched characteristics, nearly omnidirectional radiation characteristics and stable gain over UWB frequency range makes it suitable for portable UWB systems.

In this paper, a planar, compact, and low cost printed microstrip line fed pentagon-shaped ultra-wideband antenna offering dual band notched characteristics response is proposed and investigated. By introducing modified V-shaped slots in the pentagonal patch and hexagonal electromagnetic band gap structures near the feedline, dual band notched response can be realized. The proposed antenna is successfully simulated, designed, and fabricated on an FR-4 substrate. The measured results show that the proposed antenna having dimensions of 35 × 33 × 1.6 mm 3 has a bandwidth over the frequency band 2.7-10.6 GHz with magnitude of S 11 ≤ −10 dB (VSWR ≤ 2), except 3.7-4.6 GHz (C-band Satellite Communication) and 5.16-6.08 GHz (WLAN) frequency bands. The presented antennas show small group delay variation, nearly omnidirectional radiation pattern and stable gain at working frequencies. Satisfactory results have been obtained in frequency and time-domain analysis of the proposed antenna. The formulation of the center frequency of dual notched frequency band is also proposed.
