“…Recent developments of electronic chipsets with lower cost and higher power (see the "Beamformers" section) have significantly contributed to renewed interest in active array antennas. More specifically, the cost of fully active phased arrays has recently dropped thanks to the advancement of Si multichannel chips to be used for Tx/Rx modules [44], [45], [46], [47], [48], [49], [50], [51], [52], [53], [54], [55], [56], [57], [58], paving the way to the realization the Satcom phased arrays that are now commercially available.…”

L ow-Earth orbit (LEO) constellations are revolutionizing the world of satellite communication (Satcom), providing new opportunities to manufacturers and operators and enabling innovative and attractive services to users. The main advantages of low-orbit satellite systems are • more extended coverage of the surface of Earth that permits the availability of Satcom links in areas not served by geostationary Earth orbit (GEO) systems • reduced latency that proves to be fundamental for real-time and mission-critical applications

We propose a 1D beam steering high gain hybrid reflector-phased array antenna system for enhanced data rate wireless communication at Ku-band (12-14 GHz). The proposed hybrid antenna system consists of a D = 50 cm offset parabolic-cylindrical reflector with f /D = 0.4 fed by an 8 × 4 dual linearpolarized stacked patch phased array antenna placed along the focal line of the reflector. The paraboliccylindrical reflector has the property of a wide-angle beam steering along the cylindrical axis as compared to a conventional parabolic reflector. A complete implementation of the dual linear-polarized phased array antenna with the silicon RFIC chipset based beamforming network and integrated with aluminum offset parabolic-cylindrical reflector is reported. Cavity model and physical optics approximations are used to analyze the radiation characteristics of the phased array and the induced currents on the paraboliccylindrical reflector surface, respectively. Furthermore, the multilevel fast multipole method (MLFMM) is used along with the method of moments (MoM) in TICRA GRASP for a comprehensive analysis of the proposed hybrid reflector system. The peak directivity of the reflector pattern is around 27 dBi for both the X-polarization and Y-polarization, and a beam scanning of ±30 • is achieved along the cylindrical axis of the reflector for 3 dB reduction in the gain. The analytical and computed results of the proposed hybrid reflector-phased array antenna system are experimentally verified.
