Hello to you all,
I have during the last few week been working on an slot antenna design with a microstrip feed, center feed with an openended quarter wavelength stub. I have worked a bit backwards, I modeled an existing design I found in a box at work and tried to optimize that. This existing design is not good (S11 min -4.5 dB in 2-3 GHz).
In the middle of this work I started to ask myself if it would be possible to split the work into two parts. First optimize only the slot in a ground plane and when I'm happy with the resulting resonace frequency and bandwidth, then I worry about the feed (will be feed via an offset stripline with a ground pin at the slot).
Is it even possible to feed a slot with a HFSS port of some sort and make it act as a "perfect" feed?
How do you otherwise work to simplify the modeling/design/optimization?
Best Regards
