“…Furthermore, for achieving dual notched bands, etching of slots having different shapes on the radiating element has been adopted by the researchers. C -shaped slots [12, 13], U -shaped slots [14, 15], combinations of C -shaped and U -shaped slots [16], SRR and SIR type slots [17], and L -shaped slots [18] have been presented in some literature. Different types of slots on the radiating patch create interference on the surface current, and as a result, the antenna becomes non-responsive at this frequency.…”

“…However, the single notched band would not be sufficient to implement the design for practical applications. So, UWB antennas with dual band-notched properties have also been investigated and designed [12][13][14][15][16][17][18][19][20][21][22][23]. To attain a single notched band effect, mushroom type EBG structure [5], grounded stub [6], and C-shaped stub [7] beside the feedline have been realized.…”

This article presents the design and performance analysis of a printed microstrip ultra-wideband (UWB) antenna consisting of the slots in the ground plane and radiating patch. A meandered S-shaped slot has been introduced on the patch and an inverted U-shaped slot has been incorporated in the ground plane to realize the band-notch effect for WiMAX (3.2–3.8 GHz) and WLAN (5.1–5.8 GHz) bands respectively. The total dimension of the proposed design is 44 × 44 mm2. The fabricated antenna exhibits wide impedance bandwidth of 10 GHz (2.4–12.4 GHz), i.e., 135% of center frequency. The design prototype is fabricated, and the measured results have good agreement with simulated values. The effects of the slots have been analyzed by simulated surface current distribution. The designed antenna shows almost omnidirectional radiation patter and stable gain. The proposed hexagonal antenna may be suitable for UWB applications removing WiMAX and WLAN bands.

“…It is necessary for a UWB system to be capable of rejecting interferences with other existing communication systems, including the worldwide interoperability for microwave access system (WiMAX) operating in 3.3-3.7 GHz [4][5][6], the local area networks (WLAN) for IEEE 802.11a which operates in 5.15-5.35 and 5.725-5.825 GHz bands [2,7,8], and the C-band IEEE INSAT/super-extended systems which operate in 6.7-7.1 GHz [9]. Therefore, UWB antennas with band-notched functions to reject the unwanted frequencies are desirable.…”

In this study, a compact ultra-wideband (UWB) antenna with quintuple band-notched and wide-band rejection characteristics is studied. The proposed antenna mainly consists of a rectangular radiating patch, a microstrip feeding line, and a modified rectangular ground plane. The quintuple band-notched functions with narrow stop bands are achieved at WiMAX (3.3–3.7 GHz), WLAN (5.15–5.35 GHz and 5.725–5.825 GHz), C-band IEEE INSAT/super-extended (6.7–7.1 GHz) by using three modified inverted U-shaped slots and two symmetrical rectangular slots on the radiating path. Each stop band formed in the UWB antenna can be adjusted independently, and deep reflection zeros are formed between the adjacent stop bands. The formation of reflection zeros improves the band-edge selectivity of the stop band, and the notch characteristics are more prominent. To further study the wide stop band (C-band and X-band) with good selectivity characteristics, a pair of L-shaped open slot is added to the edges of two rectangular slots. Additionally, a pair of modified Rho-shaped resonators is located near the feeding line to realize band-notched characteristic at ITU service bands (8.025–8.4 GHz), thus a quintuple band-notched UWB antenna is achieved. The shape factor (ratio of the −3 dB bandwidth to the −10 dB bandwidth) of the wide stop band is 0.56, which indicates that the antenna has excellent band-edge selectivity. To verify the performance of the proposed design, both the time-domain and the frequency-domain characteristics of the antenna have been studied and analyzed. The simulated and measured results verify the design as a good candidate for various portable UWB applications.

“…This issue has motivated the research and the development of UWB antennas that are capable to deal with interferences in the UWB spectrum 3.1‐10.6 GHz . Recently, plentiful design methods of monopole antennas have been proposed to achieve UWB performance with band notched characteristics . In these reported works, the fixed/perpetual band notching features are produced by using simple slots etched in the radiators.…”

This paper presents a compact single-layer UWB antenna based on a coplanar waveguide structure. The antenna operates within bandwidth from 3 to 10.6 GHz (111.76%). The antenna incorporates two notch-filters, designed to mitigate possible interference with WiMAX and WLAN. This filtering function can be switched on or off, independently for each band, by using pin diodes. This feature allows fast adaptation, supporting spectrum sharing solutions with a compact and planar antenna. The simulated and measured results of the proposed antenna are in good agreement, with the maximum antenna gains dropping after activation of the filtering from 2.5 to −10 dBi in WiMAX 3.5 GHz band and from 3 to −8 dBi in WLAN 5 GHz band.
