Steerable array antennas are of significant interest to help meet the goals of 5G mobile communication systems. In this invited paper from Microwave Journal, we use a simple example of an 8x8 patch antenna array to demonstrate the usefulness of the CDF of EIRP to characterize the ability of an array to provide good EIRP in all directions.
Drawing on expertise from participants at 14 technology leaders in the wireless industry, including carriers, operators, device manufacturers, and providers of wireless simulation tools, the International Wireless Industry Consortium (IWPC) created a comprehensive report that identifies the key features, obstacles, and potential solutions for deployment of mmWave for 5G.
Wireless power transfer is an emerging technology used in many applications, including consumer electronics, electric vehicles, and biomedical implants, and will undoubtedly see continued growth over the next decade and beyond. This presentation demonstrates how XFdtd can be used to simulate and analyze wireless charging systems.
One of the planned technologies that may change the digital landscape in the early rollouts of 5G is fixed wireless access (FWA), which will provide new and more flexible wireless solutions for broadband for the last mile to the home. In this paper, we use new modeling and simulation techniques to investigate some of the most critical challenges that FWA faces for operation in the physical environment at millimeter waves.
Using a new electromagnetic/circuit co-simulation capability based on the FDTD method, the process of importing broadband circuit models into an EM simulation project, optimizing the overall design, and calculating important quantities such as S-parameters, radiation patterns, and system efficiency is demonstrated in this MicroApps presentation from IMS 2018.
This presentation demonstrates a new predictive tool for simulating Full Dimension Multiple Input, Multiple Output (FD-MIMO) in urban environments. We evaluate a hypothetical small cell base station employing FD-MIMO for cases using different numbers of transmit antennas, then analyze predicted multipath in the environment and compare performance of beamforming techniques for each of the simulated cases.
This presentation demonstrates a new multiphysics-based ESD analysis capability which allows the ESD testing process to be analyzed via computer simulation. This will save companies time and money by allowing ESD protection to be optimized during the design phase, thus reducing the number of prototypes required to be built and tested.
To simulate RF devices characterized by the measured S-parameters, the passivity enforcement method is first applied to extracting the rational models. The equivalent circuits can then be generated from the rational models. The RF devices are finally simulated using the FDTD and equivalent circuit co-simulation method. The numerical results of several examples have shown the efficacy and accuracy of the presented approach. The approach can be applied to simulating the broadband features of antennas which includes RF devices, complex geometries and materials in a single run.
