“…Various researchers have addressed the aforementioned challenge to some extent by introducing SWB antennas with multi notch characteristics. Several techniques such as the introduction of a slot in the patch/ground plane [1][2][3]; insertion of a slit on the patch/ground plane [4,5]; placing stubs [6][7][8][9], meander grounded stubs [10], and parasitic elements [11][12][13]; and employing a split ring resonator [14,15] have been used in SWB antenna design to filter out undesired frequency bands.…”

“…By adding an inverted T-shaped stub and a pair of elliptical slots on the radiator, three interfering frequencies of 3.74 GHz (under WiMAX band), 5.45 GHz (under WLAN band), and 7.65 GHz (under X band) were eliminated. In [9], by embedding a fractal stub on the radiating patch and by etching a pair of modified rectangular slots, triple notch bands from WiMAX (3.30-3.80 GHz), WLAN (5.150-5.825 GHz), and DSS (7.25-7.75 GHz) were encountered.…”

“…Some distinct techniques were already well demonstrated in achieving a wideband antenna with single/dual/triple band-notch characteristic [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][17][18][19][20][21][22][23][24][25] in the introductory section of this article. Thus, it is worth comparing the proposed design with the existing designs stated in the literature as presented in Table 3.…”

A compact concentric structured monopole antenna for super wide band (SWB) applications with triple notch band characteristics is designed and experimentally validated. The antenna covers an immense impedance bandwidth (1.6–47.5 GHz) with sharp triple notch bands at 1.8–2.2 GHz, 4–7.2 GHz, and 9.8–10.4 GHz to eliminate interference from co-existing advanced wireless services (AWS), C bands, and X bands, respectively. By loading an E-shaped stub connected at the top of the patch and by etching a split elliptical slot at the lower end of the radiating patch, the band rejection characteristics from 1.8–2.2 GHz for the AWS and 4–7.2 GHz for the C band are achieved, respectively. Further, by making use of a C-shaped resonator near the feed line, band rejection from 9.8–10.4 GHz for the X band is obtained. By varying the parameters of the antenna, the notch bands are controlled independently over a wide range of frequencies. The antenna provides good radiation characteristics, constant group delay response, and better gain over the pass band. The experimental results indicate that the designed antenna offers a remarkable reduction in gain and high variation in group delay over the stop bands. To characterize the wideband property and linear phase response of the designed antenna, its time-domain performance is extensively described and evaluated, which assure pulse transmission with minimum distortion.

“…The rapid development of wireless communications encourages researchers to direct their interest toward the design and fabrication of various antenna prototypes especially after the allocation of 7.5 GHz frequency band from 3.1 to 10.6 GHz for ultra-wide band (UWB) applications by Federal Communications Commission (FCC) [1]. One of the most important components in the wireless communication systems is the UWB antenna since it should achieve necessary requirements such as small size, wide impedance bandwidth, inexpensive cost, stable gain and omnidirectional radiation characteristics [2][3][4][5][6]. However, the complexity of each structure of all previously listed UWB antennas in [2][3][4][5][6] is not quite small as well as the size is not compact enough to be integrated in microwave communication systems.…”

In this paper, a compact 4-port band-notched multi-input-multi-output (MIMO) antenna with asymmetric coplanar strip (ACS) feed is presented for ultra-wide band (UWB) applications. The MIMO antenna is comprised of four semi-elliptical radiators with ACS feed for UWB applications and it is printed on inexpensive FR4 substrate of size 48 × 52 mm2 with ɛr = 4.4 and 1.6 mm height. The impedance characteristics of the suggested MIMO antenna ranges from 2.7 to 11 GHz with a band-notched behavior from 3 to 4 GHz to reduce the interception with WiMAX applications, and the isolation level over the achieved band is more than 20 dB between any two adjacent elements. Moreover, the radiation pattern of the proposed UWB antenna is almost omnidirectional with an average realized gain of 3.5 dBi over the entire achieved frequency band. The proposed ACS-fed antenna is confirmed by fabricating and measuring it's impedance and radiation characteristics. Finally, good consistency between simulation and measured outcomes is obtained confirming the validity of the MIMO antenna for real-life UWB wireless systems.

“…A U-shape slot on the radiator and an L-shape slit on ground plane of [8] bans WiMax/WLAN frequencies, whilst WLAN/X-band ranges are prohibited by a pair of parasitic elements in the wide slot of the antenna in [9]. On the other hand, [10], [11] presents triple band-notched systems. Patchs and partial grounds of these systems have been implemented with a variety of C-shape and U-shape slots that deny the radiation within WiMax/WLAN/X-band regions.…”

A wide-slot ultra-wideband (UWB) antenna with on-demand band rejection characteristics that can serve underlay cognitive radio is presented in this paper. This antenna is designed to work in twelve operation modes; one to cover the whole UWB while each of the rest modes excludes one or more of the ranges that are allocated for Worldwide Interoperability for Microwave Access (WiMax), C-band, wireless local area network (WLAN), X-band and International Telecommunication Union (ITU) in a single, dual, triple, quad or penta band rejection state. A spiral shape slot in the patch and three slots mainly based on half-circular structures in the ground plane are the means to create the desired frequency notches. A positive-intrinsic-negative (PIN) diode across each of these slots is used to enable/disable band(s) rejection process. Configuration of the proposed antenna to the desired mode of operation is decided by the state of its four PIN diodes. This work is simulated by computer simulation technology (CST) v.10. It’s S11, voltage-standing-wave-ratio (VSWR) and realized gain results when combined with antenna's 25x25x0.8 mm3 compact size and the large number of modes and states, all ensure its capability to eliminate or reduce the interference within the targeted bands and hence being suitable for the applications of underlay cognitive radio.
