“…Furthermore, Table 2 lists the comparison of presented antenna with other existing studies. Though the antenna proposed in [ 24 , 25 , 26 , 27 ] is comparatively smaller than that of this work, it is observed that the fractional bandwidth of the proposed antenna is relatively larger than the fractional bandwidth reported by the authors and the gain is comparable. The size and fractional bandwidth of the proposed antenna in this work is superior to that of the reported work in [ 28 , 29 , 30 ], as shown in Table 2 .…”

A novel compact tapered-slot-fed antenna (TSA) with anti-spiral shape and lumped resistors is presented for ultra-wideband (UWB) applications. Unique coplanar waveguide (CPW) to coplanar strip (CPS) feeding structure and exponential slot are designed to ensure the continuous current propagation and good impedance matching. With a pair of anti-spiral-shaped structure loadings at the end of the antenna, the radiation performance in lower operating band can be enhanced obviously. The typical resistor loading technique is applied to improve the time domain characteristics and expand the bandwidth. The fabricated prototype of this proposed antenna with a size of 53 × 63.5 mm2 was measured to confirm simulated results. The proposed antenna has S11 less than −10 dB in the range of 1.2–9.8 GHz, and the group delay result is only 0.4 ns. These findings indicate the proposed antenna can be taken as a promising candidate in UWB communication field.

“…Besides, in Table 4, the performance of four different high‐gain antennas is listed for comparison with this paper. In References 26‐29, four common methods for improving antenna gain were proposed. As can be seen from Table 4, this paper has advantages in the −10 dB impedance bandwidth, −3 dB gain bandwidth, minimum half‐power lobe width, and maximum gain.…”

A kind of compound optical lens (COL) inspired by metamaterials whose unit cell is a closed symmetric S‐type resonator (CSSR) is designed to enhance the gain and directivity of the antipodal Vivaldi antenna (AVA). COL, composed of a plano‐convex lens and a double‐convex lens, can generate a very narrow beam with a half‐power beamwidth of 11.2° at 12 GHz. Traditional metamaterial lenses can only convert spherical waves into plane waves. Although the gain will increase, the beamwidth of the antenna is still very wide. COL can focus the plane wave transformed from the spherical wave, which makes the radiation beam extremely narrow. The proposed antenna has a −10 dB impedance bandwidth of 169.2% (1.0‐12.0 GHz) and a −3 dB gain bandwidth of 133.3% (2.0‐10.0 GHz) and a maximum gain enhancement of 5 dBi. The experimental results of the antennas agree with the simulation results. The proposed antenna is eventually a suitable candidate for wireless communications and radar applications.

“…e works reported in [29,30] are UWB antennas where single-layered FSSs are employed to enhance gain. e reported structures with overall dimensions of 84 × 84 × 1.6 mm 3 and 33 × 33 × 1.6 mm 3 attained peak gain of 8.7 dB and 7.9 dB, On the other hand, UWB antennas presented in [26,34,[37][38][39][40][41] introduced doublelayered FSS for gain enhancement. A wideband and highgain microstrip antenna with H-shaped resonator insertion is presented in this paper for self-powered wireless Wi-Fi applications.…”

In this article, high-gain ultra-wideband (UWB) monopole antenna is presented. The UWB monopole antenna is a semicircular-shaped antenna with a semicircular slot at the top side. The bottom plane consists of partial ground with triangular and rectangular slotted structures to improve the impedance bandwidth of the proposed antenna. In order to enhance gain, a 6 × 6 metallic reflector (FSS) is placed below the antenna. The performance of the offered design is validated experimentally. The simulated results show resemblance with the measured results. The antenna resonates for the UWB ranging from 3 to 11 GHz. Moreover, the integration of FSS improves the average gain by 4 dB, where peak gain obtained is 8.3 dB across the UWB. In addition, the reported unit cell having dimension of 0.11 λ × 0.11 λ gives wide bandwidth (7.2 GHz) from 3.3 GHz to 10.5 GHz. The performance of the proposed antenna determines its suitability for the modern day wireless UWB and GPR applications.
