“…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.…”

“…However, as intrinsic drawbacks, the gain of sparse array would decrease roughly proportional to the reduction of number of radiating elements [16] and a strict sidelobe level (SLL) requirement is hard to be accomplished for sparse array especially in scanning situation [17]. These shortcomings might explain the reason why sparse array antenna has never been put into practical use in SATCOM terminals till now, 2 International Journal of Antennas and Propagation except for few demonstration systems developed by ESA which might still be far from real application [18].…”

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.

“…The option presented in this section is dividing the antenna into passive subarrays, with the minimum possible losses, in order to drastically reduce the number of active integrated circuits like amplifiers or phase shifters [13][14][15][16][17][18][19][20][21][22][23]. Some phase control is needed at the radiating element level and one of the problems is how to obtain information about the losses added in these situations.…”

-This paper presents new antenna topologies for 5G communication systems. The objective is the study of low losses distribution network technologies and the radiating elements for low profile antennas for 5G applications. Different technologies are considered as PCB technology, LTCC technology and metallized 3D printing in terms of design procedures, transmission losses and manufacturing processes in order to contribute to these types of technologies. Different designs and prototypes are done to validate these antennas for 5G communication systems.

A Toolbox of Subarrays for Optimizing Wide-Angular Scanning Arrays Using Trade-Offs Between Scan Loss and Side Lobe Level

2021

A novel approach is proposed for building a planar array derived from linear arrays using a toolbox of different types of subarrays located parallel and perpendicular to the linear array axes. The array design assumes constant element patterns and focuses on rectangular array applications with one dimensional, wide-angular beam scanning. Optimization criteria concern a trade-off between side lobe level performance, directive gain scan-loss, reducing the number of element controls and maximizing the use of phase-only elements for beam steering. All subarray configurations and functionalities, for improving the full array performance in sidelobe level and scan-loss compensation, are analyzed and validated in detail. The step-by-step integration of different subarrays starts from the center part of the array. This center part is a linear subarray along the major axis of the rectangular array with uniform maximum amplitude and spatially stretched. This subarray is combined with cross-line subarrays perpendicular to this center axis. At both edges of the center array, two in-line, uniform-amplitude and stretched subarrays are added and combined with cross-line subarrays. The amplitude distribution of the 3 in-line subarrays and the cross-line subarrays allows for lowering the sidelobe level in the plane of scanning. Finally, at both ends of the three in-line subarrays, subarrays with two and five elements are applied for reducing the scan-loss. By assuming cos(ϑ) element pattern results are given for a planar rectangular array with 41 elements length and 3 elements width. To lower cost and higher power efficiency, the array uses only 33 multi-bit phase shifters, 12 1-bit phase switches, and 4 attenuators for amplitude control. Optimized broadside and 60 • scanning patterns are compared and show improved performance in directive gain D = 24.4 dBi (broadside), D = 19.9 dBi (60 • ) and in SLL = −21.6 dB (broadside), SLL = −19.5 dB (60 • ).
