One approach to take for small apertures in solid sheets is to reverse
the model. That is model the equivalent dipole, you will have far fewer
elements and no meshing issues. Due to the duality between E and H
known as Babinet's priciple, this is vaild method.

They list an 80 MHz and up and a 200 MHz and up chamber on this site, with

Hi Bob
This article in Issue 46 of the EMC Compliance Journal may help.
I thought a slot is driven with a potential across the closest sides.
Radiation occurs due to current at the far ends. Like two short dipoles spaced
a distance (1/2 wavelength with a resonant slot) apart. So at horizontal slot
has the E-field vertical and the H-field horizontal. The polarization
Jeff,
You are technically correct if the device can only be considered a telecom
accessory and not an ITE device.
That is why I recommended Michael discuss the matter with CQC who issues the
certificates. If there is any question the device could be considered an ITE
device the
