“…The time domain and frequency domain performance of a printed super wideband antenna is presented in this design [17], with a VSWR less than two and frequency ranges ranging from 400 MHz to 16 GHz. In design [18], a compact wideband antenna with an L-shaped radiating element size of 30 × 30 × 1.6 mm 3 and an F4B substrate material with 1.6 mm height are utilised. The operating frequency of an antenna ranges from 2.11 to 5.01 GHz.…”

A compact extreme wide band (EWB) modified ellipsoid monopole antenna utilising electromagnetic band gap (EBG) technology is developed on a Rogers RT/Duroid 5880 substrate for high frequency millimetre (mm) wave applications including cellular, satellite, radar, and medical imaging. The proposed antenna design has an overall dimension of 40 mm × 30 mm × 0.787 mm and achieves EWB characteristics with a frequency range of 23.16 GHz to 776.59 GHz, a fractional impedance bandwidth (FBW) of 188.41%, and a bandwidth ratio (BR) of 33.53 by using a tapered feed and an EBG technique. The proposed antenna design attained a maximum peak gain of 17.91 dB and a peak radiation efficiency of 99.4%. On the basis of its high impedance wide bandwidth (IBW), FBW, BR, peak gain, and peak radiation efficiency, as well as its omnidirectional radiation properties at resonant frequencies, this compact antenna has the potential to be utilised for EWB applications. The HFSS 3-D solver is applied to characterize and analyse antenna performance.

“…Moreover, the defected ground structure (DGS) is one of the most significant techniques for achieving antenna compactness in terms of size or resonant frequency 9 . With the DGS and parasitic patch technique's help, a compact broadband antenna for LTE/WLAN/WiMAX applications has been proposed in Reference 10. The antenna was designed on a 1.6 mm‐thick square F4B substrate with a footprint of 30 × 30 mm 2 .…”

In this article, a compact planar heart‐shaped antenna based on countersink and partial ground plane techniques is proposed to operate as a multiband device for modern wireless systems. With a surface area of 28.5 mm2, the countersink technique (CT) has been developed to achieve high electromagnetic antenna performance. The CT consists of a particular multilayer configuration that uses two distinct materials where one of them with a radiating element on its top is placed inside another. In this article, a 508‐μm thick Rogers RO4350B with a radiating patch designed on its top is thermally embedded into a 1.524 mm thick FR4 HTG‐175. The slits are used to get multiband behavior, and their combination with the defected ground structure results in about 79.58% reduction in resonant frequency compared to the conventional antenna. A mathematical model is developed to predict the resonant frequency of the proposed antenna configuration. After modeling the heart‐shaped antenna with an electromagnetic simulator, its prototype was manufactured and validated through experimental measurements. The CT considerably improved the antenna's performance compared to the use of a single layer technology for the same antenna configuration. The return loss read from −10 dB shows that the proposed antenna covers multiple modern wireless applications, including LTE bands, 5G, WLAN, WiMAX, and Unlicensed National Information Infrastructure (UNII) radio bands. Furthermore, the antenna operates as narrowband and wideband simultaneously on its lower/middle and upper operating frequency bands. A close agreement is found between simulated and measured results across all the frequency bands.

“…18 Similarly, CPW-fed step shaped microstrip antenna is used to enhance the bandwidth for UWB applications by Jose et al. 19 Different types of antennas are being designed to enhance the bandwidth of proposed antennas by various researchers, [20][21][22][23][24][25][26][27][28][29][30][31][32] though the antennas exhibit wider bandwidth but the size of most of the antennas is quite large.

Spiral-shaped UWB antennas, which are differ from each other in terms of feeding structure are presented in this manuscript. CPW and microstrip line feeding are used to excite the designed antenna to obtain different performance parameters. The overall physical dimensions of proposed antennas are 27 × 27 × 1.6 mm 3. These antennas are designed on low cost FR4 glass epoxy substrate with 1.6 mm thickness and dielectric constant 4.4. Impedance bandwidth (S 11 < −10 dB) obtained for measured CPW-fed antenna is 176.82% ranging (1.23-20.0 GHz) and microstrip line-fed antenna is 169% ranging (1.68-20.0 GHz). Various performance parameters of both the designed antennas are observed and calculated, such as, radiation pattern, gain, group delay, and radiation efficiency, which all are in the acceptable range for distinct UWB communication and other wireless standards. The optimized designed antennas are fabricated and tested for the validation of results and comparison among simulated and measured results of antennas have been made and found in good agreement with each other.
