Hi all,
I designed a UWB antenna that works from 2.55GHz to 12GHz, I used FR4 for simulation with er=4.4. do u think if I implemented it on FR4, does it work correctly?
Is FR4 substrate of PCB?
Hi,
I think you can try design with FR4 substrate first and see the results. What i know for UWB it is better to use other substrate such as Rogers, Taconic etc since FR4 provide more loss. But, there is researcher that prove that FR4 also can operate in UWB frequency (up to 10.6 GHz) but the efficiency was not so good. So, better you try with FR4 first.
