Spotlight on Enhancements

to XFDTD v6.4

1) Antennas in XFDTD

One of the major applications for XFDTD is in the area of

antenna design and analysis. While earlier versions of XFDTD

have always offered features that assist designers to obtain

solutions quickly, v6.4 includes addition expanded capabilities.

The earlier version of XFDTD provided a single output

window for antenna results. Now, due to the expanded

features and capabilties, the results from antenna

Antenna (includes diversity)

calculations are provided on three separate tabs. Some of

2) Material Libraries in XFDTD

the main features to be added are:

· Antenna Diversity providing correlation between

The material handling and recording of material data has

antennas in the same model giving:

been greatly enhanced in v6.4. User defined libraries of

­ Range

materials have been added.

­ Max gain

­ Max lobe direction

Material data may be loaded from existing models:

­ S‑parameter information (2 parts)

· Import from an existing geometry file

­ Efficiency

· Import from a set of directories containing geometry files

· Antenna over an infinite ground plane

­ At this time the ground may only be PEC but a lossy

ground calculation is under development

· Ludwig gain

· Antenna efficiency may be calculated over the full

pattern, upper hemisphere, open sky and user‑defined

partial pattern

· Displaying 3D patterns while viewing numerical results

Creating Material Libraries

The new tabs are shown below:

Material data may be loaded, saved, edited and deleted

to/from libraries in many ways:

Power/Efficiency

Material Library Definitions

These capabilities are in addition to the hierarchical

importation of material data from CAD files.
