Slotted Waveguide Antenna Links and Software

September 1st, 2007

All we know trevor marshal design – here is another approach in designing slotted waveguide. 😉

Firs thing is of course 10ghz book in chapter seven


Next thing is hlssa program :

Hlssa programs are used to design position of the slots over the waveguide surface.

There are several versions og this one in the net – hlssa54 is first one in German.

there is hlssa61e – version in English and as I support ver 61 isthe new one 🙂

Some links for hlssa program : – English version – pic – pic of antenna


Here some links that I found useful :

First :

Cut-off calculator for square waveguides :


Some pictures of simulations /these ones are NOT mine / :




Next there is applet in java which give us way to see what tm modes we have inside the waveguide based on freq and dimensions.



And finally a place where to choose standard waveguide tubbing –


So we have all thing needed to design our new waveguide for the frequency that we need.


This is just collection of links that You may find useful. This is not tutorial. But this is basic for beginning building slotted waveguide.If You are interesting there is a lot of reading in the net – Good luck!
