A 60 GHz antenna array design is simulated in XFdtd to demonstrate suitability for use on wireless Virtual Reality headsets. The resulting array produces a fan beam which may be steered by varying the phasing between the elements resulting in broad coverage. The design is simulated mounted on a section of a virtual reality visor.
Design and Simulation of 28 GHz Beamforming System and Antenna Array for 5G Network Base Stations
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.

EM Simulation of 28 GHz Series-Fed Patch Antenna Array for 5G
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.

5G mmWave Channel Modeling with Diffuse Scattering in an Office Environment
The millimeter wave frequencies being planned for 5G systems pose challenges for channel modeling. At these frequencies, surface roughness impacts wave propagation, causing scatter in non-specular directions that can have a large effect on received signal strength and polarization. To accurately predict channel characteristics for millimeter wave frequencies, propagation modeling must account for diffuse scattering effects. Wireless InSite’s diffuse scattering capability is based on Degli-Esposti’s work.
