Abstract

The manuscript introduces a novel Swastik-shaped 8-Port MIMO configuration boasting exceptional isolation and gain characteristics. Its adaptable design allows for easy expansion to accommodate 16, 32, or 64 radiating elements, while a low-profile substrate helps reduce costs. Through meticulous iteration and optimisation, the shape of each radiating element is refined, leveraging variations in the ground layer length and radiating patch radius to achieve optimal performance. Employing orthogonal placement of two radiating patches with opposing isolation responses facilitates the selection of the most effective design structure. Performance optimisation includes the strategic integration of stubs. Fabrication and testing validate the design’s authenticity, showcasing a multiband response spanning 5.3, 7.3, 8.3, and 9 GHz. Notably, the optimal structure achieves a peak S11 of −23.9 dB and a bandwidth of 1.10 GHz, alongside over 60 dB of isolation and an 8 dB gain response, surpassing existing designs. Diversity parameters were checked to check the suitability of the design as a MIMO antenna. All responses lie within the acceptable spectrum. The challenge for most other available structures is to achieve an expandable design by optimising and balancing isolation, gain, and multiband performance, which the proposed design addresses. The proposed design is compared with other suitable designs, and their effectiveness is identified. These attributes render the proposed configuration ideal for Wi-Fi networks and short-range radar applications, marking a significant advancement in MIMO technology.
