Design of MIMO Antenna with Reflector-based Isolation Technique for mm-Wave Applications

2024-08-07T05:01:24+00:00

This work is focused on mutual coupling reduction among the antenna ports at mm-wave frequencies, which are frequencies of interest for 5G communication. Initially, the design and simulation of a single-port T-shaped wideband antenna resonating at 26 GHz with a frequency range of 24-28 GHz have been presented for possible Multiple Input and Multiple Output (MIMO) applications. The single-port wideband antenna has been extended to four-ports, and a reflector approach has been utilized to lessen mutual coupling. This isolation strategy reduces the mutual coupling by 5 dB, which is verified through software simulations. The isolation enhancement is also verified using surface current distributions.

Innovative and unique generative design solution for the leg part of a robot using Autodesk Fusion 360 CAD software

2024-08-07T05:05:34+00:00

Generative design is the innovative and novel feature of Fusion 360. As AI has become a common and compulsory tool in every search engine, the concept of generative design has also been for the designing software, to generate optimum models of designs. To showcase the concept above, in this paper four best outcomes of the generative design of the leg-2 have been discussed with tabular, pictorial, and graphical analysis. Leg-2 is the name given to the component of one of the glass cleaning robots. This paper will also show how a design is being optimized through multiple iterations, about the structural load and other constraints. For all four case studies/outcomes mass, stress and displacement analysis is presented graphically with respect to different types of materials. The results of these case studies are found within the critical yield strength values of respective material along with mass optimization through generative design analysis.
