0.8-15GHz Discone Antenna

[Docgi 12]

Hi guys,

I wanted to share a Discone antenna which has UWB radiation performance. As you can see the results below, antenna works very well between 0.8-15GHz. You may try to increase this up to 18GHz cause I's almots there.

All the dimensions you will see are the half of the exact value, except discone heigth and the gap between cone and disk. It's very simple design and in HFSS I cut the design half twice from the center. This way I got the quarter piece of the actual 3D model. Since this design is 360 degrees symmetrical, cutting it like this and doing simulation is 4 times faster. But the key is that the design must be symmetrical. If its 360 degrees symmetrical you can even cut it to 1/8, it's up to you.

Disk thickness and cone thickness are 1mm. I didn't show feeding connector dimensions but you may simply use 50ohm bulkhead or panel mount SMA connector.

My mistake, by saying "All the dimensions you will see are the half of the exact value"

They all are the exact value. In my design I wrote diameter, here I wrote radius. I mixed it up, lol

Use the same values in pictures
