what are the modes in current distribution in UWB antenna

Hello,

Maybe you should tell us what type of UWB antenna you have in mind (with frequency range). The wave bahavior in a 2D flared tonque like design is different from a multiple resonating patch.

What do you mean with "resonating modes" (quarter/half waave, number of knots, etc)?

we r simulating a UWB antenna with a band notch characterstics between 5.12 -5.85 GHz. our impedence bandwidth is 3.1-10.6 ghz.my guide asked abt its current distribution and resonating modes i.e TE10, TEM OR QUASI TEM etc.,
