“…It can be observed from the Table 2, that proposed antenna is compact in size and exhibit higher value of negative gain at both rejected frequency band as compared to the other references except reference. Also, the VSWR bandwidth of proposed antenna is more in comparison to references [30–36, 38, 39, 41‐43], except references [40,44,45]. While, the bandwidth (VSWR ≤2) of references [40,44,45] is better but the size of antenna designed in these references is large in comparison to the proposed UWB antenna.…”

A compact ultra‐wideband (UWB) printed monopole UWB with dual band‐notched characteristics has been designed and investigated in this manuscript. The Wi‐MAX and wireless local area network (WLAN) band rejection characteristics have been obtained by employing the circular ring and arc‐shaped slot along with rectangular slot in radiating patch. Overall size of proposed UWB antenna is 27 × 27 × 1.6 mm3, which consists of sprocket gear wheel shaped structure as a core radiating patch element and excited by using 50 Ω coplanar waveguide feed. The proposed antenna exhibits the UWB frequency spectrum from 3.1 to 10.6 GHz along with Bluetooth frequency range 2.4–2.48 GHz without disturbing overall dimensions of antenna. Proposed antenna reveals the measured VSWR operating bandwidth of 10.0 GHz in the frequency range from 2.0 to 12.0 GHz along with Wi‐MAX and WLAN rejected bands. Moreover, proposed antenna adorns the measured gain of −8.28 and − 9.98 dBi at rejected frequency bands, whereas, at other frequencies, it changes between 1.5 and 5.0 dBi. The radiation efficiency of proposed UWB antenna varies from 84% to 97% except rejected frequency bands. Group delay and radiation pattern have also been analyzed and found appropriate for the current UWB applications. Finally, the optimized structure of antenna with dual band rejection characteristics has been fabricated and tested for the authentication of simulated results. Both the results are compared and are found in good agreement with each other.

“…Although the antenna in [45,46] have a single tunable notch-band by using varactor diode, it cannot avoid the interference from other narrowband and the notch band tuning range is still narrow. The antennas in [47,48,25] have realized dual band-notch characteristics by introducing pin-diode, but the band-notched antenna can only operate in two or three states, since the pin-diode only have two conditions ("ON" state and "OFF" state). The proposed antenna with switchable and tunable band-notched characteristics in [49] have been achieved by mounting both Pin diodes and varactor diodes.…”

In this paper, a miniaturized ultra-wideband( UWB) microstrip antenna with independent tunable double band-notched characteristics is presented, which consists of the semicircle ring-like radiating patch with an elliptical-shaped slot and double split ring resonators(SRRs) on the top surface of the substrate and defected ground structure(DGS) on the bottom surface of substrate. The operating frequencies have range from 1.3GHz to 11.6GHz(S11<-10dB). The double band-notched characteristics have been achieved by etching elliptical-shaped slot at the radiating patch and placing double C-shaped SRRs at the both side of the microstrip feed line. By loading varactor diodes at the gap of the elliptical-shaped slot and the double C-shaped SRRs and changing the reverse-bias control voltage of the varactor diodes, the notch frequency can be electronically tuned efficiently. The experimental results, which are agree well with the simulated results, demonstrate that the proposed antenna have created the notched frequency band shift from 2.47GHz to 4.19GHz(1.72GHz) and 4.32 GHz to 5.96GHz(1.64GHz) when the reverse bias voltage vary from 0V to -30V corresponding to the junction capacitance of varactor diode has decreased from 2.67pF to 0.63pF, which imply that the proposed antenna with band-notched characteristics has the capability to suppress the narrow interference signals which cover the wireless local area network(WLAN) and world interoperability for microwave access(WiMAX) band. Furthermore, the proposed antenna structure only has the electrical size of 0.26λ*0.19λ at 1.3GHz. Compare to the related reported antennas, the proposed antenna has achieved compact size, tunable dual band-notched characteristics and good band-notched performance simultaneously to the best of our knowledge. It is believed that the proposed antenna will have a very valuable prospect in the fields of wireless body area network (WBAN), UWB communication, Internet of Things(IoT), etc.

“…Multiband operation was achieved by employing various techniques including stacking [13], defected ground structure [14], frequency selective surface FSS [15], Electromagnetic Band Gap (EBG) [16], Photonic Band Gap (PBG) [17], and by using Metamaterial [18]. Several other well established techniques have also been employed to convert a normal single band microstrip patch antenna into a multiband antenna such as cutting slots in the radiating patches [19], using dual fed technique [20], using parasitic patches with same dimensions as that of radiating patches [21], and a pair of double split ring resonators (DSRRs) on either side of the feed [22]. A common limitation for this type of antenna is narrow bandwidth.…”

This paper presents a triple band proximity fed 2 × 1 array antenna with defected ground plane. The proposed antenna configuration is composed of two radiating elements, and both radiating elements are made of a pattern similar to the first iteration level David fractal geometry. The proposed David fractal 2 × 1 array antenna is designed and simulated on an FR-4 substrate of thickness 1.6 mm and dielectric constant 4.3 by using the CST Microwave Studio simulation tool. In order to improve the radiation characteristics of the antenna, an H-shaped defect is etched in the ground plane. The antenna is fabricated and tested. The experimental data show good agreements with simulation results. The fabricated triple band fractal 2 × 1 array antenna resonates at 2.527 GHz, 3.329 GHz, and 3.742 GHz having bandwidths of 303 MHz, 99 MHz, and 102 MHz, respectively. The proposed fractal array antenna can be used in mobile applications such as Wi-Fi, WLAN, Bluetooth, and Wi-Max.
