This presentation demonstrates how XFdtd can be used to simulate and analyze wireless charging systems.
This example uses XFdtd® EM Simulation Software to analyze the performance and interaction of two antenna systems operating at 4G (860 MHz) and 5G (28 GHz) in close proximity in a smartphone design. The 4G antenna is intended to produce a broad pattern for wide coverage while the 5G array should produce narrow beams that can be steered by varying the phasing between elements. The 4G antenna is an inverted-L design and is located at the top of the phone. The 5G antenna array consists of four Yagi-Uda elements that are near the 4G antenna but offset by a conducting block.
An 8x8 planar antenna array creates narrow beams capable of scanning large sectors in front of the antenna. This example focuses on displaying typical simulation results for beams and possible plots of coverage from the full array and combinations of sub-arrays.
Series-fed patch elements forming an array are simulated to demonstrate antenna performance and beamforming including S-parameters, gain, and effective isotropic radiated power (EIRP) at 28 GHz. Beam steering is performed in one plane by adjusting the phasing at the input ports to each of eight elements.
Performance of a 12-port handset antenna array operating in LTE bands 42/43 (3400-3800 MHz) and band 46 (5150-5925 MHz) is analyzed in XFdtd for varying hand hold positions on the device. The results computed include S-parameters, Gain, Efficiency and Envelope Correlation Coefficient.
ESD testing requires the use of many hardware prototypes, which is time consuming and expensive. The ability to simulate the ESD testing process and pinpoint locations in wireless devices susceptible to ESD damage would be extremely valuable and allow engineers to reduce the number of prototypes required to design products for minimal ESD damage. This presentation introduces a multiphysics-based ESD capability in Remcom's XFdtd that analyzes ESD testing 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.
How does Wireless InSite differ from planning tools? The most important differences emerge when users need to simulate 5G millimeter-wave and MIMO systems. This paper presents 10 cues that your organization may need a channel-modeling tool to supplement your 5G network planning efforts.
Wireless InSite’s Communication System Analyzer provides capabilities for assessing the performance of LTE, WiMAX, 802.11n, and 802.11ac systems. This example investigates WiFi throughput coverage in a house provided by 802.11ac routers operating at 5 GHz using an 80 MHz bandwidth.
Accurate calculation of RCS at millimeter wave frequencies requires sufficiently detailed geometric representation of the target and physical modeling techniques that capture the scattering effects of small facets. Highly detailed facet models and traditional methods for calculating RCS at these frequencies can often result in very long run times. Using Remcom’s X3D with Physical Optics (PO) and Method of Equivalent Currents (MEC) model for calculating RCS, accurate results can be achieved within reasonable run times.
In this app note, a MIMO antenna is created and simulated to generate return loss, coupling, and gain patterns for several different configurations and operating modes of the device. The ability to form either omni-directional or focused beams is also demonstrated.
