Antenna Design

Accurate results are easily obtained after generating the antenna using the XFdtd^®® 7.0 sketching tools.

A 10-turn helical antenna is simulated in XFdtd^® to demonstrate the far-field circular polarization plotting capabilities of the software.

An optimum gain pyramidal horn antenna (see Antenna Theory and Design by W. Stutzman and G. Thiele, John Wiley & Sons, New York, 1981, pgs 413-415) was simulated using XFdtd^®.

A circularly polarized microstrip antenna is simulated in XFdtd^® and return loss results are compared to measurements.

A broad band antenna designed for WLAN applications is simulated in XFdtd^® using a variety of variable mesh configurations and the return loss is compared to measured results.

Case Study: Using XFdtd^® to Position Antennas on an Aircraft.

The ability of XFdtd^® to generate arrays is used in this example of a three patch antenna array.

In this example XFdtd^® is used to compute the input impedance, radiation gain pattern, and SAR of a patch antenna embedded inside a human body.

This example shows the ability of XFdtd^® to import complicated CAD files, mesh them, and produce accurate results.

The same horn antenna geometry shown in other XFdtd^® examples on our web site is used here to demonstrate the ability of the MPI version of XFdtd.
