“…Different system architectures have been studied in [2], where a system consisting of 24 antenna tiles with 8x8 antenna elements (AEs) is proposed. Achieving the required level of integration remains a big challenge with the previous limit being reached by [3] with LNA, phaseshift, summation, filtering, downconversion and antenna for an 8x8 array with one linear polarization on a single 98x98mm PCB and by [4] with LNA, phaseshift, frequency discrimination and antenna for 156 dual polarized AEs on a single 20cm diameter PCB. This paper presents another major step in functionality and integration with 128 Ku-band inputs on a 94x94mm footprint (i.e.…”

A highly integrated Ku-band (10.7 -12.75 GHz) planar phased array receiver of 64 antenna elements is presented. It features instantaneous reception of the full Ku-band (2.05 GHz wide) in two orthogonal polarizations with scan angles up to 75 degrees by using time delay instead of phase shift. The receiver is part of a system for satellite reception on board of moving vehicles. Two SiGe RFICs were developed, packaged in ceramic BGAs and assembled onto a 15-layer PCB which integrates the antenna elements. An outline of the system is given along with a detailed description. It sets a new standard in integration density.

“…The NF as listed in this work is simulated over the full antenna scan angle to give realistic performance expectations. Unfortunately these numbers were not available in the references, but based on the monolithic microwave integrated circuit (MMIC) used in [9, 10] a minimum NF of 2 dB is found.…”

A highly integrated Ku-band (10.7–12.75 GHz) planar phased array receiver of 64 antenna elements is presented. It features instantaneous reception of the full Ku-band (2.05 GHz wide) in two orthogonal polarizations with wide scan angles by using time delay instead of phase shift. The receiver is part of a system for satellite broadcast TV reception on board of moving vehicles. Two SiGe radio frequency integrated circuits (RFICs) were developed, packaged in ceramic BGAs and assembled onto a 15-layer printed circuit board (PCB) which integrates the antenna elements. An outline of the system is given along with a detailed description. It sets a new standard in integration density. The receiver has extensive analog signal processing at intermediate frequency (IF)-level. A novel bipolar implementation for true time delay is proposed, with a continuous programmable delay range of 0…80 ps with less than 2.5 ps group-delay variation in 2 GHz bandwidth (BW). The wide BW calls for a constant group-delay implementation in the IF chain. The receiver (RFIC) consumes only 132 mW per channel. Each channel has 40 dB gain.

“…Printed patch is a maturely developed antenna with advantages including low profile and low fabrication cost. It has been widely used in COTM terminal antennas in recent years [18,22], thus demonstrating its feasibility in SATCOM application. For these reasons, printed patch is chosen as the radiating element for the proposed sparse phased array.…”

A novel antenna array architecture for low-cost and compact SATCOM mobile terminal is presented. Based on equal-amplitude aperiodic phased array with fewer active chain numbers, it possesses advantages including lower weight, less cost, and higher power efficiency compared to conventional periodic phased arrays. It is implemented with printed patch antenna so that it guarantees compactness. The elements position and dimensions are jointly designed, with an effective sparse array synthesis strategy that takes actual patch antenna design constraint into consideration, to obtain a maximum array aperture efficiency. Executable and practical approach for variable dimension patch antenna designing, including defect substrate element and small scale array, is introduced and utilized to implement proposed sparse array. Full-wave simulation results demonstrate the advantages of proposed array antenna as well as the effectiveness of corresponding design approach.
