inductive post

[in′dək·tiv ′pōst]
(electromagnetism)
Metal post or screw extending across a waveguide parallel to the E field, to add inductive susceptance in parallel with the waveguide for tuning or matching purposes.

It is consisted of two perpendicular SIW structures, three SIW to microstrip line transitions and an inductive post.
The inductive post which is short circuited between the up and down sides of SIW is placed at the center of the power divider.
Therefore, what needed to be optimized to realize the output port matching after the modelling of SIW structures are the dimensions of SIW-microstrip line transitions, and the size as well as location of the inductive post.
The inductive post placed at the centre of the power divider has great impact on the reflection and scattering of the input signals.

Inductive posts are used at the corners to help the wave travel fluently and reduce the return loss.
The ceramic loaded iris was first matched with a single large inductive post to form a single cavity.
The ceramic loaded iris was then matched with inductive posts on both sides, forming a two-cavity filter.
This window grid was then matched with inductive posts, as shown in Figure 5.
The iris was matched at 500 MHz using two inductive posts.
