For narrow band antenna since they are tuned to a particular freq with some narrow band it is easy to calculate the matching network for the tuning. in case of uwb antenna since we are dealing with a wide band what can be done to improve matching (for example suppose for some range if the s11~ -5db how to improve the matching at that freq without deteriorating the matching at the the other frequency).
i am using 3-10 ghz bands
1. one possible option for this is to use multiple matching networks but then they will increase the insertion loss.
2. since i will be using a chip antenna not a micro strip antenna so i can not use any of antenna modification (like ground modification for better antenna matchings.)
3. it may be possible to do some modification in the board so possible to have distributive elements instead of lumped elements.
what are some possible ways to achieve this.
