array antenna is vilkinson antenna and it have an excitation wilkinson power divider
but it was bad F/B.
Hi
Simplest way is to place a kind of metallic reflector lambda/4 from your radiant system.
by logerthemic approach
EBG structures have shown quite good results in improving front to back ratio.
EGB is one of the solution, but as cost effective is metallic reflector plate to avoid/reduce back side radiations.
I am trying to make a chromosome ideogram (map genes on a chromosome) in an interactive way; if you click on a section of the chromosome, it expands and shows the corresponding genes in that region.
