“…eam steering of antennas is an essential task in communication [1] [2], especially, for SatCom-on-themove applications [3]. Beam steering can be achieved either electronically, mechanically, or hybrid techniques where both electronic and mechanical steering are combined for optimal results [4] [5].…”

Geometry plays an important part in the characteristics of meta-cells used to design beam steering metasurfaces. One of the most desirable aspects of these cells is a large phase shift range that can be achieved with good transmission amplitude. However, the existing and most commonly used geometries for these cells are not able to produce a complete 360° phase range with an acceptable level of transmission amplitude. In this article, we present a new cell geometry, Flanched-Cross, that has superior transmission properties due to its unique shape and parametric variability than the commonly used geometries. The results are verified in simulation and further confirmed through prototyping and measurement. One- and two-dimensional steering are also performed for a dual-polarised base array to confirm the applicability of Flanched-Cross cell for beam steering purposes.

“…However, they are bulky and take a relatively larger physical space. Moreover, the mechanical tilting often requires heavy-duty motors, and they limit steering speed [3]. Electronic steering, on the other hand, is usually of low profile.…”

“…Nevertheless, this technique requires a sophisticated algorithm for optimizing the desired metasurface in addition to extra microchip components such as field-programmable gate arrays (FPGA), and thus it becomes expensive for SatCom operators [12]. Furthermore, despite the reduced cost, the MSAT also involves complicated assembly and is therefore, like other hybrid phased arrays, not suitable for mass production [16], [17].…”

Low-Profile Beam Steerable Patch Array With SIW Feeding Network

et al. 2020

This paper presents a novel beam steerable array antenna that encompasses fully planar, low profile and lightweight characteristics for satellite communication (SatCom) applications. The proposed array contains a wideband linear source generator (LSG), an array of circular patches, and an inductive surface. The LSG is designed based on the substrate-integrated-waveguide (SIW) technology, whereas the patches are regarded as coupling circular scatterers, placed on the inductive surface for converting surface wave into the radiating wave. Each scatterer acts as a location-dependent phaser that can tailor the farfield behaviour to leverage beam steering, and is achieved by changing its distribution mechanically. A prototype of the proposed design has been fabricated and measured to evaluate the antenna performance. The measured results are in good agreement with the simulated results. The array antenna operates well with S 11 <-10 dB in the frequency band of 10.75-12.5 GHz and has stable radiation performance with beam steering capability of nearly ±60 • in the elevation plane. The total height of the proposed array is about 5.1 mm (0.19λ •). It is envisaged that the proposed antenna array will empower small moving platforms due to low cost, low profile and suitability for mass production.
