“…Stacked patch structures are popular in multiband antennas as it provides more control on the radiation characteristics of individual operating bands where each patch supports one or the other operating band. Moreover, it offers enhanced impedance, higher axial ratio bandwidth, CP purity, and better gain as compared to traditional patch radiators . A dual‐band L1 and L2 CP operation has been achieved by placing two asymmetric slit square patches and a cross‐shaped slotted square patch over a reactive impedance surface in Reference .…”

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 triple‐band stacked patch CP antenna covering L1, L2, and BDS‐1 bands has been investigated in Reference . A four L‐probe feeding network excites the antenna while two shorted annular rings formed with a circular array of metallic vias is used to suppress the mutual coupling between the patches.…”

“…The shorted annular ring (SAR) antenna can significantly reduce the excitation of surface waves [16], [17], resulting in less back radiation and high gain. These characteristics make the SAR antenna ideal for applications where the supporting substrate or ground plane of the antenna is small, in which case diffraction of surface and lateral waves from the edges of the structure may be quite significant for conventional microstrip antennas.…”

In this paper, an octagonal shorted annular ring (OSAR) antenna array is presented based on 130-nm SiGe BiCMOS technology without any post-processes. The OSAR antenna consists of annular ring patch, an array of shorted pins and ground which is formed a cavity to enhance the gain and reduce surface waves. The 1 × 2 OSAR antenna array is designed and fabricated with the die area of 550× 1100µm 2. The measured −10-dB impedance bandwidth is more than 17 GHz (303-320 GHz). The proposed on-chip antenna array is achieved a measurement perk gain of 4.1 dBi at 320 GHz and the simulated radiation efficiency of 38 %.

“…On the other hand, GNSS transmits circular polarization signal hoping that the axial ratio is as small as possible. Moreover, the frequency of GNSS now extends from 1.166 GHz to 2.502 GHz [23] which the corresponding wavelength is approximately 120-273 mm much larger than the thickness of the radome. Hence, the EM wave transmitting through the dielectric slab may be unsuitable to be decomposed into parallel and perpendicular components, and the ray-tracing method cannot produce reasonably good results.…”

High-precision global navigation satellite system (GNSS) antennas employed on the fixed ground station are usually equipped with radomes, which are potential in yielding degradation of key parameters of antenna such as axial ratio and gain. This paper presents a study on the deterioration of high-precision GNSS antenna caused by the radome using electrically EM simulations including comparison of different geometries, materials, and heights of radome. Based on the study, an optimized radome model is proposed to minimize the axial ratio and gain degradation of antenna. Finally, a prototype of proposed radome is fabricated and measured. A good agreement between simulated and measured results evidently illustrates that the geometry, material, and height of radome are set appropriately.
