“…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.…”

“…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.

Abstract-An L/C dual-band dual-polarized (DBDP) shared aperture microstrip array is proposed in the paper. In the array, the novel sandwiched stacked patch structure is proposed and employed to improve lower band bandwidth for given antenna thickness. Several key issues regarding the proposed structure are discussed, including: 1) merits of proposed sandwiched stacked patch structure; 2) C-band feeding method; 3) radiation performance in both bands. A prototype array of L/C DBDP sandwiched stacked patch is designed and fabricated to verify the feasibility of the proposed structure, where the measured data are presented in the paper.
