Hi everyone, I have designed a dual-band microstrip patch antenna for LTE and WiFi application. The antenna operate at 2.6GHz for LTE and 5.0GHz for WiFi. I have started the design process by designing the 5.0GHz WiFi then introduce two inverted U slots to generate the second 2.6GHz. The impedance matching for the first 5.0GHz WiFi is okay, but I c

I have a question about CPS Balun design for array antenna.
My concern is that my array antenna have normally a common ground, for example a patch array antenna.
Then I would like to convert microstrip transmission line to stripline using CPS Balun.

Why do you need a step-by-step proceedure? You have already done one in HFSS, but just using a different material.
Don't know the LTCC material to use? Ask your vendor for specs on the FIRED materials that he uses. Select the one that meets your criteria.
When designing with LTCC, just remember to design with PRE-FIRED dimensions, but simula

you can followed these steps in HFSS to create a SIW structures.
1- draw a box for substrate
2- draw patch & ground plane(top and bottom of sub respectively)
3- draw cylinders around the patch for creating the SIW.
4- select top faces of all cylinders that you draw in previous step,then go to modeler-surface-create object from face

If you really want to learn about the micro-strip patch antenna then pick any IEEE paper and try to learn how to design the same on cst or HFSS. I suggest this is the best way to gain knowledge. There are number of post, blogs and videos available online on how to design microstrip antenna.
