this is another problem ... !!! the main thing is to keep up the real dimentions,,,!!!
-
it does not see too good ... !!! what do you mean with 1 patch...??
-
I like it, when you make a test of it?
-
a variant of copper wire and platband
-
not
-
in the past I think I used another dielectric with other dimensions
-
I did this simulation today and I did not have time to optimize something ... !!! to me that looks,,,!!!!
-
your CST file I can not open ?! My *cst file,,,!!! E-Patch.cst
-
,,,create another type of material (polystyrene) in CST material library, with er=1,2 and load it...!!!
-
what kind of material?
-
what kind of dielectric spacer did you choose? with what dielectric constant(relative permittivity)? the best is polystyrene,,,!!!
-
"There are two pieces of each one for the 1720MHz frequency and the other for the 1840MHz frequency
-
This is what you want?
-
ok Erkin, but I saw you know how to work in autocad, it's simple, it's just rectangles patches ... !!!
-
"Ok but these dimensions are very good for my antenna, 1780-1870 MHz VSWR <1.2
-
how much?
-
I think that the other 3+3 patches are glued to the screen with insulated spacers
-
yes , it is good,,,!!!
-
More recently, this has now appeared
-
no, I do not have this ... but for you I do anything .. !!!
-
Erkin, this antenna is quite complicated in terms of impedance adjustment lines. Regarding the recommendation, I think the patch antenna with adaptive lines from the wire is easier to execute
-
Another type of 1280MHz patch antenna And this represents an improvement of the antenna This antenna has a wider bandwidth
-
I am wanting to make a CP patch antenna for 1.3GHz, but am struggling to find a design with dimensions online. I did a simulation of this antenna but with an elliptical cut in the patch, which provides a wider bandwidth and for the 2.4GHz frequency
-
Biquad antenna in the air with parasitic director-it is necessary a laser cutting of the vibrator element (biquad patch)
-
,,,biquad on PCB with parasitic director
