Re: Simulating objects in FarField of Antenna

Hi Thorsten, I guess I was not entirely clear. I was referring to the Fraunhofer distance i.e. 2*D^2/lambda as the far field distance. In my case D = 2* lambda, therefore, Fraunhofer distance = 8* lambda. My application requires me to place the lens really far off from the antenna at about 30 * lamb...

Simulating objects in FarField of Antenna

I have a series-fed patch antenna whose far-field region starts at (8* lambda) units. There is a dielectric lens structure (compresses the beam) placed well in to the far-field of the antenna at about (30* lambda) units. If I use a nf2ff function to create the box around the lens and antenna volume,...

Meshing and Simulation Time of Antenna Setup

Hi, I am new to openEMS and FDTD and currently in the process of migrating my work from FEM solvers. I am trying to simulate a patch antenna and a accompanying lens to get a narrow beam at 60 GHz as shown in the setup below. MySetup.png As can be seen the distance between the source antenna and the ...
