“…The effective inductance and capacitance of the microstrip line varied by adding the capacitance, inductance and resistance of the introduced slots. As the area of the slot is directly proportional to its effective inductance, any increase will generate effective inductances, which results in changing the cut-off frequency [33]. However, after introducing the notches, the antenna rejected the band spectrum from 3.75 to 4.9 GHz, with a peak VSWR of 42 at 4.5 GHz.…”

This paper presents the design and realization of a compact printed ultra-wideband (UWB) antenna with notching characteristics for compact devices using a genetic algorithm. The antenna is capable of mitigating an adjacent sub-band ranging from 3.75 to 4.875 GHz, mainly used by many applications and standards such as WiMAX, WLAN and sub-6-GHz. The notch band functionality is achieved by etching out two symmetrical slots from the pentagonal radiating element. The simulation and measured results demonstrate that the proposed antenna overperformed compared with state-of-the-art antennas in terms of compactness with an overall size of 20 mm×15 mm×0.508 mm. Moreover, the proposed design shows a large bandwidth in the UWB region with a fractional bandwidth of 180% with respect to the center frequency of 5.25 GHz. The antenna also presents omnidirectional radiations all over the operation band and a good return loss performance.

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.

“…Firstly, cutting slot technique is used, such as step‐shaped, Ω‐shaped, or modified U‐shaped etched on the radiating patch; U‐shaped, L‐shaped, or inverted U‐shaped etched on the ground plane; and ring‐shaped slots etched on the feed line . Secondly, band‐notched functions can be obtained by utilizing tuning stubs on the patch or ground plane . At last, parasitic patches and stubs are employed to the UWB designs, which could also realize the band‐notched characteristics .…”

A compact coplanar-waveguide (CPW)-fed ultrawideband (UWB) antenna with quadruple rejected bands is proposed. To realize the bandwidth requirement of UWB communication, a gradient folk-shaped radiating patch and a symmetrical ground plane are employed, which help to cover a frequency band from 2.7 to 10.7 GHz. In order to obtain four rejected bands within the UWB frequency band, four different slots including a capshaped slot, two meandering slots, and a split-ring are utilized, which contribute to generate rejected bands at C-band (3.60-4.32 GHz), wireless local area networks bands , and International Telecommunication Union service band (7.8-8.2 GHz), respectively. Excellent band-notched features are obtained by optimizing the positions and lengths of the four slots. Simulated and measured results show that the proposed antenna is especially suitable for UWB communication. K E Y W O R D S compact antenna, CPW-fed, quadruple rejected bands, UWB
