Re: [UKMicrowaves] Microwave PCB design


I always thought of them as 1/4 waves .. but, I could be wrong ...

If it is a quarter-wave radius (or anything over the 1/10 or 1/8 wavelength rule of thumb) then it's into transmission line territory and all starts getting rather complicated. There's a lot of confusion about power / ground planes where the size means there's a significant transit time involved.
