Suspended StripLine Broadside Coupler

Calculate the characteristic parameters of Quasi TEM mode stripline coupler. Of cause, not being homogeneous the stripline is no longer pure TEM. However this property has been exploited to make very good HPA filters.

Frequency (1Hz.. 100Ghz)

Line width mm (1000.. 0.001)

Shield Spacing mm (1000.. 0.001)

Substrate Height

Dielectric (100.. 0.9)

Reference termination (1..350 Ohms

A reference load is required for calculation of the Quarter wave coupler characteristics (defaults to 50 Ohms).

Only zero thickness will be dealt with. However for thickness less than 1% of the substrate thickness is going to make neglible difference.

However if you are looking for an broadside coupler on a real substrate, then choose a substrate from the catalog but the track thickness is not accounted for.
