Catherine antenna

Hi admins. I'm trying to assemble a 4g antenna, for the frequencies 1800, 2100 and 2300, with this Catherine Antenna. Can you help me simulate it? Thank you.

Sorry. Yes, the dimensions are the same. Right now in my country there is a lot of talk about the Catherine antenna. Looks very interesting in the attachment. To maximize the performance of this antenna is it enough to add a 120 mm reflector?

I have tried to connect this antenna to a 2.4 Ghz wifi router. Antenna works fine. Can master Joymi simulate this antenna for 2.4 Ghz frequency, and how many dbi gain is obtained? Thank you in advance.

the Blue and RED coax should be NEW CABLES straight to the card...(if possible to solder in there)

High losses

It is very difficult. I came up with a much simpler one. For making with your own hands. Simplicity of design and availability of materials.

Use it.
