“…The antennas presented in [12][13][14][15][16][17] are relatively larger in size and offers band-notching in a single frequency band. UWB antennas of comparable size have been proposed in [18][19][20][21][22][23][24][25]; however these designs give band-notching in two frequency bands. The UWB antennas covered in [26][27][28][29][30][31] use relatively complex mechanisms to attain band rejection in triple frequency bands.…”

“…The band-notched characteristics in UWB antennas are obtained by using various techniques such as slots in the feed line, ground, or radiator [10,11]. Till now researchers have applied various techniques to obtain single [12][13][14][15][16][17], dual [18][19][20][21][22][23][24][25], and triple [26][27][28] band-notching of narrowband channels operating within the UWB spectrum. In [12] a 50 × 42 mm 2 UWB antenna has been designed to suppress or notch the WiMAX frequency band (3.3-3.8 GHz) by using electromagnetic bandgap structures.…”

“…The pin diodes need additional resources (lines and dc-supply) to operate it in the reverse/forward bias mode. The WLAN and WiMAX frequency bands have been notched by using the techniques mentioned in [18][19][20][21][22][23][24]. In [18] the authors have designed a 38.…”

“…Two complementary split ring resonators (CSRR) are also employed on both sides of the microstrip feedline to stop the WiMAX frequency band (3.3-3.7 GHz). In [19], slots are etched in the ground. Similarly, resonators [20] in the top layer are used for WLAN and WiMAX band rejection.…”

The Federal Communication Commission (FCC) has authorized the use of unlicensed ultra-wide band (UWB) spectrum in the frequency range from 3.1 to 10.6 GHz for a variety of short-range applications, including wireless monitors and printers, camcorders, radar imaging, and personal area networks (PANS). However, the interference between coexisting narrowband channels and UWB signals that share the same spectrum should be avoided by designing UWB antennas with band notch characteristics. This work presents a printed monopole antenna (PMA) with slots of different shapes etched in the radiating element to obtain band rejection in the three coexisting communication bands, i.e., Worldwide Interoperability for Microwave Access (WiMAX), Wireless Local Area Network (WLAN), and International Telecommunication Union (ITU). A rectangular slot is etched to reject the WiMAX band (3.01-3.68 GHz), an upturned C slot stops the WLAN band (5.18-5.73 GHz) while an inverted-U slot halts the ITU frequency band (7.7-8.5 GHz). The proposed antenna occupies a volume of 32 x 30 x 1.6 mm3 and it radiates efficiently (>90%) with a satisfactory gain (>1.95 dBi) in the unnotched UWB frequency range. The simulations are performed in High Frequency System Simulator (HFSS), while the measurements are conducted in antenna measurement facility and found in close agreement with the former.

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.
