CPW - FED SLOT ANTENNAS
 
     
 
Structure on IE3D



Parameters:

Substrate thickness = 0.813 mm, permittivity = 2.2, permeability = 1

Conductor thickness = 0.005 mm, conductivity = 4.9´107 s/m

Slot length = 78 mm, width = 2 mm

Center conductor width = 2 mm

Simulation Result:

The measured data and FDTD result are from: H. S. Tsai and R. A. York, "Applications of planar multiple-slot antennas for impedance control, and analysis using FDTD with Berenger's PML method", IEEE AP-Symposium Digest, Newport Beach, CA,1995, pp. 370-373.

It takes IE3D about 3 sec/freq on Pentium 133 (geometry file: cslolt1.geo)
