“…For both antennas, the S11 plots show multiple resonances from two resonators, which are judicially combined to achieve wide impedance bandwidth. The impedance bandwidth obtained is greater than that for the CP antenna with ring-ring combination presented in [6], and the CP antenna presented in [9,10]. A comparison of this bandwidth and other data are summarized in Table III.…”

A hybrid perturbation scheme is used in this paper to achieve wide axial ratio (AR) bandwidth and beamwidth from circularly polarized (CP) microstrip patch-ring antennas using a single probe feed. Perturbations in the diagonal corners of a square ring and a square patch arranged in a stacked configuration are introduced to achieve the circular polarization. First, an enhanced axial ratio bandwidth is obtained when a combination of a square ring and a square patch with negative perturbations is used as parasitic and driven elements respectively. Next, circular polarization with wider axial ratio bandwidth, wider beamwidth, and lower cross-polarization is obtained when a combination of a driven square patch with positive perturbation and a parasitic square ring with negative perturbation, termed as hybrid perturbations, is used. This antenna has a footprint suitable for small satellite applications (e.g. CubeSats) and its operating frequencies cover the allocated S-band downlink frequencies of NASA Deep Space Network (DSN) and NASA Near Earth Network (NEN).

“…Some comparisons were made as presented in Table 2 to clarify the novelty of the presented antenna, as can be seen, the MPA proposed in 9 outperforms the SIW slot antennas 14,15 when it comes to bandwidth and radiation efficiency. However, the SIW slot antennas have higher integration compatibility.…”

In this article, a circularly polarized (CP) microstrip patch antenna (MPA) is proposed. The antenna adopts a substrate integrated waveguide (SIW) cavity and a microstrip patch as the feed structure and the radiator, respectively. In consequence, the patch dominates the radiation and improves the radiation efficiency, while the asymmetric SIW cavity enhances the bandwidth and generates a pair of degenerate modes, which provide the quadrature phase shift that the CP radiation requires. By this mean, the proposed antenna not only brings up a novel feed structure for CP MPA and improves its effective bandwidth, but also circumvent the limitation of the SIW cavity slot antenna, which is low radiation efficiency.Plus, the presented antenna remains the advantages of SIW structure, including high Q factor, high integrate compatibility, and so forth. The antenna was fabricated and measured, and the presented antenna exhibits an impedance bandwidth of 12% (from 2.09 to 2.36 GHz), an axial ratio bandwidth of 7.73% (from 2.15 to 2.32 GHz) with a minimum gain of 7.89 dB. The experiment results indicate a good agreement with the simulation.

“…The bandwidth of the antenna can be enhanced by employing the stacking patch, so that the ARBW of the antenna could reach 6.6% (2.38–2.543 GHz) 1 . In Liu and Zhu, 2 a low‐profile and high‐gain CP patch antenna is designed while the axial ratio bandwidth (ARBW) is around 6%. Although this technique has a good effect on expanding the bandwidth of CP antennas, it greatly increases the complexity of the antenna structure.…”

We proposed a broadband e‐shaped circularly polarized (CP) patch antenna with single‐point feed, and the feed point is located at the center of the antenna. The structure of this new antenna includes a ground plate and an e‐shaped patch placed on a substrate. The measured impedance bandwidth of the proposed antenna is approximately 17.89% (3.47–4.15 GHz), and the measured 3‐dB axial ratio bandwidth (ARBW) is about 9.47% (3.63–3.99 GHz). The antenna can achieve the gain of 8.4 to 8.7 dBi within the ARBW. And at the center frequency (3.8 GHz), right‐hand CP to left‐hand CP isolation of the antenna can reach −33 dB.
