Vivaldi Antenna in tutorialDesign

Re: Vivaldi Antenna Design

If I needed an omni and had to use Vivaldi's I could consider a circular array with the elements aligned like spokes of a wheel.

A biconic would have similar bandwidth and be easier to fabricate. It would probably cost less too.

Re: Vivaldi Antenna Design

The beamwidth is propotional to the antenna's openning,

So, to make your E-beamwidth wider, you may:
1) reduce the antenna's length, or
2) reduce your's antenna flare-angle
