“…A dual‐feed stacked patch antenna 9 was designed to operate at L‐band (1.575 GHz) and S‐band (2.2 GHz), which requires two separate branchline‐couplers as the feeding network for the dual‐band CP radiation. In Reference 10, an aperture‐coupled patch antenna is designed for a 3 U CubeSat, which operates from 2 to 2.45 GHz. This antenna is fed by a sequentially rotated‐phase network for the wideband CP radiation.…”

“…This antenna is fed by a sequentially rotated‐phase network for the wideband CP radiation. The sequentially rotated‐phase feed, 7,10 or dual‐feed, 9 however, complicates the antenna design, as well as increases the fabrication cost. In Reference 11, a slot antenna fed by coplanar‐waveguide is presented for CubeSat cross‐links/inter‐satellite communications.…”

In this paper, a metasurface‐based antenna with broadband circularly polarized (CP) radiation is presented for S‐band CubeSat applications. It consists of a single‐feed slotted patch and a metasurface composed of 4 × 4 periodic metallic plates. The patch is sandwiched between the finite metasurface and ground plane to excite surface wave resonances for the broadband operation. The antenna is designed to achieve the geometry and characteristics, which are compatible with any CubeSat standard structure. The final prototype with an overall size of 0.64λmin × 0.64λmin × 0.026λmin (λmin is the free space wavelength referring to the lowest operational frequency) has been realized and tested. The experiments result in a |S11| < −10 dB bandwidth of 24.64% (1.85‐2.37 GHz), an axial ratio < 3‐dB bandwidth of 15.23% (1.94‐2.26 GHz), and a broadside realized gain of 5.6 to 6.7 dBic. Moreover, the antenna achieves a good broadside right‐hand CP radiation with symmetric pattern, high front‐to‐back ratio, and high radiation efficiency.

“…However, the radiation direction of the traditional low-profile antenna is in the normal direction of the ground plane. Their application on the surface of flight vehicles is severely limited because they cannot cover the forward and backward area of flight vehicles [ 7 , 8 , 9 , 10 ].…”

A high end-fire gain, low-profile surface wave antenna with capacitive feed structure is presented in this paper. The proposed dielectric-metal surface wave antenna is composed of a dielectric slab that is mounted on a metal carrier and a low-profile feed structure. The feed structure is composed of a monopole radiation pin that is loaded with a circular metal plate and a grounding pin. The profile height of the antenna is only one-tenth of the operating wavelength. With a good end-fire performance and low profile, the antenna is very suitable to be conformally mounted on the surface of flight vehicles. The proposed antenna was designed and manufactured at the center frequency of 6 GHz. Measured results demonstrated that the proposed antenna had a bandwidth of 7.33%, ranging from 5.89 to 6.33 GHz, and the antenna reached a high gain of 9.76 dBi with a length of 122.96 mm (2.45 λ) in the end-fire direction.

“…It is well known that circular polarization (CP) can be obtained from linear orthogonal polarizations with an appropriate feed network to radiate them in-phase quadrature [5][6][7][8][9]. The above method has many advantages such as wide bandwidth and dual sense of polarization when a quadrature hybrid is used in the feed network [5].…”

A Telemetry, Tracking, and Command Antennas System for Small-Satellite Applications

Circularly polarized (CP) antennas are used in space applications for telemetry tracking and command (TT&C). In this paper, we present an antenna for a TT&C system that can employ only four antennas to achieve a wide quasi-isotropic coverage. The proposed single-feed circular polarized annular patch antenna is low profile and compact. It exhibits a wide impedance bandwidth of 19.7%, wide-angle circular polarization with an on-axis maximum gain higher than 6 dBi and an axial ratio below 4 dB in the frequency band 2.0–2.3 GHz. The developed low-cost antenna can be used for small-satellite data downlink where only two right hand circular polarized (RHCP) antennas and two left hand circular polarized (LHCP) antennas would be required since each antenna has an adequate CP gain on a wide angle. A prototype antenna has been fabricated and measured. The experimental validation shows a good agreement of the measured impedance bandwidth, axial ratio, and far-field pattern with the ones predicted by numerical full-wave study.
