Halo Antenna 145Mhz

[Pat Byl]

Hello,

I would like to design a halo antenna on vhf 145 Mhz

the first step, is to draw a circle and open the circle.

the perimeter is 1000 mm open on 14 mm

it's a gap

after that I want to optimize the value of this gap.

until now, I don't find to draw this

thanks in advance

Hello,

Use an arc instead of a circle. Arcs are open curves. Go to Draw menu > Arc.

See the description in this link: https://antennasimulator.com/index.php/knowledge-base/arc/

I attached an example.

Tony
