In this article, a dual circularly polarized high gain superstrate integrated Xband antenna is designed and analyzed for CubeSat applications. The proposed antenna consists of a metallic patch, multilayer space qualified printed circuit boards, and a dielectric superstrate with a high relative permittivity on top of the patch to establish a suitable resonance condition for high-gain operation. The driven patch is fed by a 3-dB hybrid coupler for the generation of dual (left hand circular polarization and right hand circular polarization) circular polarization.The antenna exhibits an impedance bandwidth of >18.5% (7.75-9.4 GHz) with a peak gain of >16 dBiC. The achieved antenna performance makes it suitable for CubeSat missions at X-band.

“…I N modern wireless systems, circularly polarized (CP) wave is used as a powerful technique to mitigate multipath interference, polarization mismatch, and the Faraday effect. As a result, CP antennas [1] have been developed widely for several applications in radio frequency identification [2], global positioning system [3], wireless local area network (WLAN) [4], satellite communications [5], [6], synthetic aperture radar [7], and so on. Moreover, dual-CP antennas, which can generate both right-and left-hand CP (RHCP and LHCP) radiations, are expected for not only polarization diversity but also frequency reuse [8].…”

This paper presents a dual-circularly polarized (dual-CP) antenna with simple configuration, low-profile, and wide bandwidth. Its primary radiating element is an aperture-coupled patch loaded with a stacked patch for a wide operational bandwidth. A single-section hybrid coupler is utilized as a feeding structure of the antenna to generate dual-CP radiation. Different from the priors normally requiring both wideband radiator and wideband feeding structure, this work demonstrates that the wideband dual-CP radiation can be obtained by combining a wideband radiator and a conventional hybrid coupler. A design operating at the center frequency of 5.5 GHz has been fabricated and tested. The measurements result in a −10-dB reflection coefficient bandwidth of 30.0% (4.66 -6.31 GHz), a 10-dB isolation bandwidth of 30.9% (4.66 -6.35 GHz), a 3-dB axial ratio (AR) bandwidth of 29.1% (4.70 -6.30 GHz), and a realized broadside gain of 5.5 -7.05 dBic. For a more robust dual-CP radiation, a low-sidelobe 4 × 4 element array of the proposed antenna has been designed, fabricated and measured. Compared to the single element design, the array prototype yields similar impedance and 3-dB AR bandwidths, but a higher isolation. The measurements on the array prototype result in an isolation of ≥ 14 dB, a peak gain of 16.3 dBic, a side-lobe level of ≤ −20 dB, and a cross-polarization of ≤ −16 dB across the frequency range of 4.7 -6.3 GHz (29.1%).

SummaryIn this paper, a 4 × 4 MIMO (multiple‐input multiple‐output) antenna with metasurface (MS), which is composed of dual circularly polarized (CP) patch antennas, is proposed for 5G (sub‐6 GHz) applications. The MIMO antenna consists of four microstrip patch antennas. In order to improve the isolation of the MIMO antenna, parasitic elements are placed on the MS and layer of patch antennas. In addition, a substrate‐integrated waveguide (SIW) structure is used at the center of the MIMO antenna for this purpose. The proposed MIMO antenna is fabricated for validation tests. The antenna has overall dimensions of 115 mm × 115 mm × 3.2 mm (1.219 × 1.219 × 0.033 , where is the free space wavelength at the lowest operating frequency in 10‐dB impedance bandwidth). The MIMO antenna has 10‐dB impedance bandwidth (IBW) from 3.3 to 3.8 GHz (14.08%), 3‐dB axial ratio bandwidth (ARBW) from 3.42 to 3.69 GHz (7.59%), and 6.36‐dBi peak gain. The isolation is greater than 28.14 dB in the n78 frequency band (3.3–3.8 GHz).
