vivaldi antenna
hi,
first i have some questions about the purpose of wideband antennas? is it possible to built a dipole that has bandwidth more than an octave? can u tell me the frequencyranges? (GHz is preferred). What are the conditions for resonance for dipoles ( working with capacity(C) and inductivity(L))?
but this is more important for me to know !!!
i have to built a vivaldi antenna( 3.1GHz -10.6GHz), i found good stuff on this board, but im not sure how to match the microstrip to the coaxcable.
is it possible to put a balun on the planar material (FR4)? How does it look like?
do i have to care about the bandwidth?
where can i find baluns when it is not possible to put lumped elements or microstrips directly on my platine? (any websites selling baluns?)
what about a direct match (sma connector), do i have to many losses?
it would be kind if u can help me and try to explain the match with some pics and values, cause it is easier to understand.
