, not only the dimensions of the patches, but also the distance between the reflector and them...!!!
-
I think this is better...
-
,,,may be 1,8GHz and 2,6GHz..!!!
-
,,, yes, those 4 curved dipoles are for lower frequencies..and they seem to have adaptive loops on the PCB.!!!
-
,,,it can still be so...
-
-
"I do not understand anything, put the quotas on my drawing above....!!! ,, and the * cst file, I cannot download it..!!!
-
Clanon, can you give me these dimensions?
-
Yes, I know this antenna, but why it has two main lobes of radiation...???!!! ,,, and I do not think it has such a big gain in directivity(with only 4patches)...!!!
-
X-polarization of com666 user...
-
,,,a radome, it"s a structure protecting radar equipment and made from material transparent to radio waves...???? ,,, polyurethane foams...??? or dielectric lens antenna,....??
-
,,,,clanon, it is easier to make the antenna from the thin tiled sheet (from the canned) ... !!!
-
,,,yes,you can..., bolts for screws with plastic spacers..!!!
-
Gentlemen, please, read this...!!!
-
Vitaliy,you must to see this too...!!!
-
Vitaliy, please use the English language...!!!
-
,,,OKAY...!!!! ,,, BUT NOW I WORK ON THIS ... !!!

Polystyrene foam can be found on all roads, even in garbage...!! If you do not want polyurethane foam spacers you can put two spacer screws but you need other dimensions ,,,for SMA 75 Ohm, you need another distance between vibrator and reflector, but this is not important, you must to try ... !!!

-
,,, okay, if you put in place of rectangular patches, elliptical patches, like, what do you say ... ???
-
,,,no,something like this...
-
,,,no,I want just a drawing...!!!
-
,,, clanon, you, can post its technical drawing...??? I am most interested in the transmission lines .. !!!
-
okay, tomorrow you will have the simulation results ... !!! But why don't you try and this simple antenna....???

I use the dielectric constant = 1.2
