Learning and Documentation
An antenna based on a transverse slotted rectangular waveguide design is realized in a substrate integrated waveguide structure and simulated in XFdtd® EM Simulation Software. The antenna scans narrow beams from near broadside to near end fire as a function of frequency. The antenna performance in terms of S-parameters, gain patterns, and radiation efficiency are determined.
A 60 GHz antenna array design is simulated in XFdtd to demonstrate suitability for use on wireless Virtual Reality headsets. The antenna array is comprised of elements each containing two patches and a parasitic element. The resulting array produces a fan beam which may be steered by varying the phasing between the elements resulting in broad coverage. The final design is simulated mounted on a section of a virtual reality visor.
This example uses XFdtd to simulate the performance of a low cost, chipless RFID system. The RFID tag is comprised of two ultrawide band monopole disk antennas mounted in a cross-polarized configuration combined with a microstrip line adjacent to six varying size spiral resonators which each represent a single bit in the RFID tag code. The system is validated using two cross-polarized log periodic dipole arrays as the send and receive devices.
This example is a more complete device for 28 GHz beamforming for 5G networks and includes an 8x8 patch antenna array, 1 to 8 power dividers and a Rotman lens initial stage. The design of the Rotman lens is performed using Remcom’s Rotman Lens Designer® (RLD) software, which produces a CAD version of the device for use in XFdtd®. In XFdtd, a set of eight 1 to 8 Wilkinson stripline power divider networks is designed to act as the connection between the Rotman lens and the antenna array. The performance of each stage is simulated and evaluated.
A proposed smartphone design that includes a 4G antenna operating at 860 MHz and a 5G array at 28 GHz is analyzed in XFdtd to determine operating characteristics and any mutual coupling. A brief study of configurations is performed to find the best positioning for each antenna.
XFdtd simulates ESD testing, enabling engineers to identify potential locations and components at risk of dielectric breakdown in their device designs prior to hardware testing. This presentation summarizes XFdtd's collection of features to mitigate ESD risk.
