“…The antenna performance of SPA‐OE‐DGS was compared to previously reported dual‐frequency antennas and summarized in Table . The SPA‐OE‐DGS in this work has high peak gains of 6.8 dBi and 12 dBi at the lower‐frequency and upper‐frequency bands, respectively, while achieving high | S 21 | (>31 dB) with a small form factor as compared to other previously reported dual‐frequency antennas . In addition, due to having multiple antenna elements, the studied antenna can be further developed to have beam steering functionality at an upper‐frequency band.…”

“…However, the antenna had low peak gains of 7.1 dBi at the upper‐frequency band. In Reference , a substrate‐integrated waveguide (SIW) antenna element was placed in the center of an annular‐ring antenna element to obtain dual‐band operation. Also, a single microstrip line was directly fed to the annular‐ring element and coupled with aperture structure to operate the SIW slot element at 5.8 and 30 GHz, respectively.…”

“…[5][6][7][8] These reported dual-band antennas do not provide the multi-operating modes of a single antenna, such as a multiband antenna, 9,10 because of the harmonics of the antenna at upper-frequency bands. 7,8 Therefore, two antennas were closely placed or integrated to operate at dual-band with a high frequency ratio. In References 5,6, a dual-feed dual-band stacked patch antenna operates at both 2.5 and 8.2 GHz bands, and folded-parallel-plate antenna covers both 2.4 and 24 GHz.…”

The designed and fabricated patch antenna covers both dedicated short‐range communication (DSRC) and Fifth Generation (5G) millimeter‐wave (mmW) bands for advanced telematics. The fabricated antenna has a small volume of 2.7λH × 2.6λH × 0.15λH, where λH is the air wavelength of the highest operating frequency. The antenna performances, such as S‐parameters, the realized gain at boresight (RG00), antenna radiation efficiency, and radiation patterns, are reported. The simulated results are in good agreement with the measured ones. Despite the fabricated antenna's compactness, port isolation higher than 31 dB was achieved. Not only high RG00s of 6.8 and 12 dBi were obtained at DSRC and 5G mmW bands, respectively, but also an efficiency greater than 90% was observed at both frequency bands. Lastly, the fabricated antenna shows better performance than the previously reported dual‐band antennas.

Vehicular communication presents a compact wideband implantable antenna for the best wireless transmission of information. The key role of the antenna is handled by the thickness of the substrate present in that antenna. Also, the shape of the antenna causes the performance characteristics. Now, vehicle‐to‐vehicle communication is the interesting task for designers to create successful and organized vehicular communication systems. This article presents a triple‐band circularly polarized conformal antenna for vehicular communication. An antenna is introduced as a triple‐band circular polarized conformal antenna and preserved a suitable mount on the vehicle surface for greater gain to provide well‐maintained operational performance characteristics. For getting circular polarization, circular cuttings are provided in the design of the proposed antenna. The radiation gives a fixed direction by providing 0.3 mm thickness. Here, use a circularly polarized antenna to rectify the signal absorption due to the contact material used in the antenna. A polyamide material is used as a substrate to get a probable successful link and improve the flexibility of the antenna. The triple‐band circularly polarized antenna is designed to operate in vehicular communication bands such as 2.4 GHz Wi‐Fi, 3.5 GHz WiMAX, and 5.9 GHz dedicated short range communication. The antenna is designed to resonate in a triple band to improve the antenna parameters like frequency response characteristics, gain, return loss, voltage standing wave ratio, left hand circularly polarization, right hand circularly polarization, axial ratio, fidelity factor, directivity, radiated power, and input impedance. Under the operating frequency bands of 2.4, 3.4, and 5.9 GHz, the efficiency of the proposed antenna is 98.48%, 97.31%, and 97.90%, respectively. The triple‐band circularly polarized conformal antenna is implemented in the high‐frequency structure simulator platform. The proposed tri‐band antenna is applicable in vehicular communication systems and healthcare for efficient wireless transmission.

In this article, the intensive investigations are carried out on a low volume compact flexible antenna for wireless applications with a novel structure model. The proposed model has considered as an elliptical‐ring with split‐triangular patch (ERSTP) antenna with the coplanar waveguide feeding to achieve dual‐bands. The ERSTP antenna is designed with polyimide material having the volume (L a × W a × h) 99 mm3. The ERSTP antenna resonates with 2.60 GHz and 3.48 GHz frequencies with a reflection coefficient of −21.92 dB and −32.14 dB and a gain of 2.39 dBi and 1.75, dBi respectively. The impedance bandwidths are 100 MHz and 330 MHz observed at two frequency bands. The proposed ERSTP antenna has operated on mobile‐worldwide interoperability for microwave access (M‐WiMAX) and worldwide interoperability for microwave access (WiMAX) bands respectively. The simulated and measured results of ERSTP antenna are in good agreement.
