Electrostatic discharge (ESD) testing is utilized worldwide by electronics manufactures and includes the use of numerous standards from organizations including the American National Standards Institute (ANSI), JEDEC, and International Electrotechnical Commission (IEC), among others. 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 from the 2019 IEEE MTT-S NEMO conference summarizes a number of ESD simulation features in XFdtd.
In this example, XFdtd is used to simulate the performance of a substrate integrated waveguide (SIW) leaky wave antenna with transverse slots. The antenna operates like a transverse slotted rectangular waveguide, but is designed in SIW for reduced cost, size, and for easier integration with planar circuits. Results for S-parameter performance, antenna gain, and efficiency are computed.
In this example, an RFID tag system is examined using XFdtd EM Simulation Software to validate its performance for use in situations where high volume usage requires very low-cost components. The RFID tag is constructed as a microstrip device with spiral resonators tuned to specific frequencies that represent separate bits of the tag code. The resonators are connected to two cross-polarized ultrawide band monopole disk antennas which receive and transmit the signal from the scanning system. The system is demonstrated with a design capable of encoding six bits that are formed by resonances 100 MHz apart between 2.0 and 2.5 GHz. The testing is done using two cross-polarized log period dipole array antennas which transmit and receive the signal from the RFID tag.
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.
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.
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.
