Slot antennas - RF Cafe Forums

RF Cafe Forums closed its virtual doors in late 2012 mainly due to other social media platforms dominating public commenting venues. RF Cafe Forums began sometime around August of 2003 and was quite well-attended for many years. By 2012, Facebook and Twitter were overwhelmingly dominating online personal interaction, and RF Cafe Forums activity dropped off precipitously. Regardless, there are still lots of great posts in the archive that ware worth looking at. Below are the old forum threads, including responses to the original posts. Here is the full original RF Cafe Forums on Archive.org

hi,

to find phase shift b/w slots you just do:

phase shift = 2*pi*(d/wavelength)*sin(beam angle) where d is distance between slots

but this equation is for slots in broadside....what about if you've slots in the narrow dimension? meaning, what's the formula for finding phase shifts between narrow-wall slots...thanks
