Wearable Dual-Band MIMO Antenna
This example demonstrates a possible wearable antenna design for dual-band use constructed of textile materials. The performance of the antenna remains acceptable as it is deformed as might happen in actual usage cases. When combined in a MIMO array, the antennas show good isolation and acceptable antenna performance.
Simulation Of Electrostatic Discharge (ESD) Testing With XFdtd
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.
Simulating A Beam Scanning Substrate Integrated Waveguide Leaky Wave Antenna 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.
Simulating Performance Of A Low Cost, Chipless RFID System In XFdtd
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.
A 5G, 60 GHz Antenna Array For mmWave Wireless Virtual Reality Headsets
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.
