hi
i want to increase the s11 parameter of the power splitter to occupy a wide bandwidth,i have changed εr value too..can anyone suggest a way to increase that s11???
 

Are you using Wilkinson power divider ? Is the width of the input feed line calculated so that it has 50 ohm impedance ?

The key is impedance matching.

Do the transformation right!

For your bandwdith (>1 octave), you may think of use multi-section (2 to 3 sections) to improve your matching bandwidth if you haven't done so!
