how to make broadband antenna wire 1.5 Meter ?

hi all,

i want to make a broadband antenna wire 1.5 meter, so it's can have VSWR less than 3:1 at Frequency 30 MHz - 90 MHz but how to make it real, because i don't have enough experience on it, is there anyone can help me, please ?

Well I am not a pro in this field BUT Search Joseph J Carr's Antena book. It will help you.

thank you for your reply, i have read that's book but i don't find any clue to solve my problem, any other specific clue mr.bluehole? :)

Well No I am not a pro in this thing. But what I know ( You may already know this) is take the Geometric mean for the band and design for the Geometricmean frequency. in your case Fm = SQRT(30x90)=51.96152MHz. Then calculate the wavelength and design your own. About VSWR design i am not sure enought.
