“…Multifunctional wireless systems are one of the present and future prospects for wireless communication, including intelligent transportation systems (ITSs) [4], [5], integration of sub-6 GHz and mmW data communication [3], integration of radar and communication (RadCom) [5], concurrent power and data communication for IoT-oriented systems [7], and synthetic aperture radar (SAR) applications. The development of such multifunction systems heavily relies on multiband antenna arrays.…”

In the development of a multifunctional and multi-standard analog frontend module in emerging and future wireless systems, multifunction antenna array is an indispensable component. To this end, the aperture-shared technique has come of age, and demonstrated significant advantages in the cost-effective design of efficient, compact, multiband, multibeam, and polarization-diversified antenna arrays, particularly with high frequency ratios. In this paper, various antenna topologies and surface architectures based on this technique, which have been proposed and developed thus far for a wide variety of applications, are reviewed, examined, and categorized to highlight the nature of electromagnetic aperture-shared schemes and merits. Finally, we briefly discuss future research directions in this context for multifunction millimeter-wave and terahertz wireless systems development.

“…This can be achieved in various ways such as time multiplexing of the aperture, subdivision of the aperture or the simultaneous generation of multiple beams from a single aperture. The last method is generally referred to as the shared-aperture antenna array [2] which can provide multiband and multi-beam operations simultaneously. In a shared-aperture antenna array, separate radiators for each application are used concurrently which are distributed across the same aperture [3].…”

In this work, a novel dual‐band orthogonally polarised, the shared‐aperture array is proposed for the L‐band and S‐band frequencies. An elliptical monopole antenna is used as a radiating element in the proposed array. In this design, the common inter‐element spacing is used for both the bands. Owing to this, L‐ and S‐band arrays have the same number of elements. The L‐band radiators are closely placed and designed taking the mutual coupling into account. The S‐band antenna follows the traditional array design process. The inter‐band coupling is reduced by using a metallic ridge in the reflector of the array. This array can be used in the dual‐band radar applications. The proposed methodology offers the modular, low‐profile and low‐cost solution for a large array. To verify the proposed concept, a prototype array of 4 × 4 elements for each band has been fabricated and tested.

“…The interlaced layout includes interlace patch with dipole/slot [9][10][11] and interlaced slot with slot/dipole [12][13], etc. [14][15] present the review and comparison for these arrays. Both the perforated structure and interlaced layout are commonly adopted in space-or air-borne applications because of their low profile performance.…”
