Is it possible to pass two different bands with one antenna? I need to pass both the 2.4Ghz and 5Ghz Wifi Bands but I don't want the stuff in-between or on either side of those bands. If you used two separate Bandpass filters how would you wire them up?
For that difference in frequency, just a diplexer is required. Amounts to a high pass and low pass filter with input in parallel. I believe there are stock diplexers sold for 2.4 and 5 GHz WLAN freq's. Try Murata filters.
However, I'm not sure how I would wire it up. I have a single antenna tuned for 2.4ghz and 5ghz WLAN frequencies. I need to feed it through a filter (diplexer?) before I amplify (12db) the signal and then split the signal 4 ways.
