Antenna Design

Simulating a Beam Scanning Substrate Integrated Waveguide Leaky Wave Antenna in XFdtd

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 5G, 60 GHz Antenna Array for use with mmWave Wireless Virtual Reality Headsets

A 5G, 60 GHz Antenna Array for use with mmWave Wireless Virtual Reality Headsets

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.

Design and Simulation of 28 GHz Beamforming System and Antenna Array for 5G Network Base Stations

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.
