This example demonstrates an antenna array for 5G 60 GHz applications of wireless communication for wearable devices such as virtual reality headsets. The antenna design for this example is from the paper by Hong and Choi of Hanyang University. The array is composed of four elements which each have two patches and a parasitic element. The parasitic element aids in producing a wider beam in one dimension to give better coverage. The beams may be steered by varying the phase shift between elements to provide near hemispherical coverage.
5G is pushing the boundaries of wireless communications and wireless device design. New innovations are needed in order to accommodate increased requirements for enhanced mobile broadband, massive machine-type communications, and ultra-reliable, low latency communications. This collection of application examples is written by Remcom’s engineers. They demonstrate how Remcom’s software can be used to solve challenges related to 5G and MIMO use cases such as MIMO and array design, 5G urban small cells, fixed wireless access, indoor WiFi and mmWave, beamforming, and more.
This example describes a more developed 28 GHz antenna array capable of forming multiple beams for use in applications such as 5G network base stations. The system consists of three parts: a Rotman lens beamformer with seven input ports and eight output ports, a series of stripline Wilkinson power dividers to split each Rotman output into eight equal signals, and an 8x8 patch antenna array. The design process consists of three separate stages. This example will describe the creation of each stage of the device and evaluate the performance of the individual stages and the full device.
Wireless InSite's high-fidelity MIMO calculations predict system throughput and bit error rate. This example demonstrates throughput analysis between three small-cell base stations employing FD-MIMO beamforming to User Equipment (UE) moving along a route, using 5G New Radio in a dense urban environment.
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.
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.
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.
