“…These values are in close agreement to the simulated axial ratio bandwidths of 5.3% at GPS L5 band, 0.7% at GPS L2 band, 0.8% at GPS L1 band, and 0.5% at the 2.3 GHz band. A wider axial ratio bandwidth at the GPS L5 band is due to the presence of two different dielectric substrates . Thickness of the substrate is also a contributing factor toward it, which increases the surface wave efficiency and thus, improving the axial ratio bandwidth in this frequency band.…”

“…CP gain of the proposed antenna is again comparable to rest with an almost stable value throughout the four operational bands. Most importantly, the proposed antenna employs a simple geometry with single probe feed requiring no complex feeding network like, ease of fabrication through traditional low‐cost techniques and attains a significantly smaller size than rest of the reported designs. This comparison clearly shows the advantages of the proposed antenna for GNSS applications.…”

“…Multiband antennas have attracted interest of researchers worldwide. A number of studies have discussed multiband CP and/or linearly polarized (LP) antenna designs with single or multiple feeding points in the open literature . Quadrifiler helixes, annular rings, slotted patches, split ring resonators (SRRs) and stacked patches are some of the popular ways to generate multiple resonances with good CP operation.…”

Design of a multiband circularly polarized antenna is proposed in this article. The antenna has a simple and compact form factor by employing single-feed stacked patch structure. It exhibits good performance at the global navigation satellite system (GNSS) frequency bands of L1, L2, and L5 and cellular communications frequency band of 2.3 GHz. The antenna has a 3-dB axial ratio bandwidth of 1.1%, 1.0%, 4.1%, and 1.5% at the four operating bands of L1 (1.575 GHz), L2(1.227 GHz), L5 (1.176 GHz), and 2.3 GHz. The antenna also achieves a gain of more than 2.2 dBiC and efficiency of more than 70% at the four frequencies. A detailed parametric study is carried out to investigate the importance of different structural elements on the antenna performance. Results are verified through close agreement of simulations and experimental measurements of the fabricated prototype. Good impedance matching, axial ratio bandwidth, and radiation characteristics at the four operating bands along with small profile and mechanically stable structure make this antenna a good candidate for current and future GNSS devices, mobile terminals, and small satellites for 5G/Beyond 5G (5G/B5G) applications.

A novel broadband dual circularly polarized (CP) array based on metasurface structures is proposed in this article. Four rotated metasurface elements fed with 90° phase difference are employed in this design, and crossed L‐shaped probes are used to achieve dual CP operation for each element. The proposed metasurface is shared by the closely spaced radiation elements to realize a compact size of only 0.69 × 0.69 × 0.03λ0, where λ0 is the free‐space wavelength at the lowest frequency of 3.5 GHz. The working mechanism of the proposed metasurface antenna element is investigated by using characteristic mode analysis. A prototype is fabricated and measured to confirm the effectiveness. The measured results show that the proposed antenna exhibits attractive features of wide operation bandwidth and good dual CP performance, which makes it suitable for 5G applications.

A pentagon shaped triple band circular polarized (CP) slotted microstrip patch antenna with asymmetric single microstrip feed line is designed. The proposed patch antenna is loaded with a pair of asymmetric slits, a pair of symmetric slots and a triangle shape truncation at the right side of the antenna. The antenna is drafted within the size of 0.43λ Â 0.43λ and resonates at 2.17, 3.08, and 3.48 GHz with impedance bandwidth (IBW; IS 11 I < À10 dB) 2.14-2.20, 3.06-3.10, and 3.45-3.51 GHz, respectively. The Axial Ratio Bandwidth (ARBW; AR < 3 dB) is obtained as 2.17-2.40, 3.07-3.10, and 3.48-3.54 GHz at the three resonances which almost cover the IBW. An additional feature of the design is that the CP bands are very closely spaced with frequency ratio of 1.36 between first and second CP resonances and 1.13 between second and third CP resonances. The obtained gain at three resonances is 3.9, 3.79, and 4.81, respectively. The CP radiation patterns are found to be stable with good right hand CP (RHCP) to left hand CP (LHCP) isolation at the boresight direction. This antenna is suitable for S-band applications. The advantage of the proposed design has been highlighted with respect to multiband CP, CP frequency ratio, compactness and RHCP to LHCP isolation. A prototype of the proposed design is fabricated and the measured results are in accord with the simulated results.
