In this video, a Remcom engineer walks through the steps to set up and tune a Ku Band microstrip lens in Rotman Lens Designer (RLD). We populate the physical, electrical, and transmission line properties and analyze the performance of the lens by plotting the array factor and beam to array phase error. This data helps us to further tune the lens by adjusting the focal ratio and beam port excitation, and then we export the S-Parameters. Finally, we discuss the various options for exporting the file and importing into XFdtd EM Simulation Software, including the use of a customized script. The script import method automatically sets up the ports and also includes the material properties.

In this example, XFdtd and RLD are used to design and analyze a 28 GHz antenna array capable of forming multiple beams for 5G network base stations.
This collection of application examples demonstrates how REmcom's EM simulation software solves challenges related to 5G and MIMO.
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.
