“…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

Given an array with defective elements, failure correction (FC) aims at finding a new set of weights for the working elements so that the properties of the original pattern can be recovered. Unlike several FC techniques available in the literature, which update all the working excitations, the Minimum-Complexity Failure Correction (MCFC) problem is addressed in this paper. By properly reformulating the FC problem, the minimum number of corrections of the whole excitations of the array is determined by means of an innovative Compressive Processing (CP) technique in order to afford a pattern as close as possible to the original one (i.e., the array without failures). Selected examples, from a wide set of numerical test cases, are discussed to assess the effectiveness of the proposed approach as well as to compare its performance with other competitive state-of-the-art techniques in terms of both pattern features and number of corrections.

“…In this sense, communications with high data transmission rates, low latency, and support for many users and devices are simultaneously required. In response to this technological progress, phased-array antennas are one of the key technologies adopted to satisfy such requirements [1], [2], [3], [4].…”

This paper presents a new passive vector modulator phase shifter (VMPS) based on a polar architecture suitable for use in advanced beamforming feeding networks. The cascaded structure of a reflection-type bi-phase variable attenuator (RTBVA) and a reflection-type phase shifter (RTPS) allows great flexibility regarding phase and amplitude control, and reduces amplitude errors in phase shifting. A printed circuit operating at a central frequency of 3.6 GHz with 5-bit phase resolution was designed and implemented to validate the proposed concept. The measured results showed a 360 • phase shift range, an average insertion loss of 2.4 dB at 3.6 GHz, a root-mean-square phase, and a gain error of 1.3 • and 0.06 dB, respectively. This VMPS also allows an amplitude control range of ∼25 dB and an operational bandwidth of 0.7 GHz (19.4%).
