Hello, can any one can convert this antenna to 5.700ghz and simulate it?

,,, for the construction of the antenna on the frequency of 5.7 GHz the coefficient k = 0.4284 is used to transform the dimensions...

it should be studied and simulated , since impedance 200 ohms (originally) will be 100 ohms for two ...but 4 of those would make a direct adaptation to 50 ohms (1:1 balun required)

and YES

hi

i want to build this antenna for 3570 mhz frequency. using this guide:

Quados antenna online calculator - 3G-aerial



http://www.qsl.net/yu1aw/ANT_VHF/quados.pdf



is "quados 8" a good choice?

can i use thicker wire?

why there is no connection to the reflector?

also i don't know where solder the wires exactly! 

two sides of the antenna or the two ends of the antenna?
it has a 4:1 balun so 3 center conductors must be soldered to antenna

should i solder two ends of the antenna together? or they must be seperated?

please draw it for me if you can.

thanks a lot
