,,,see this... ,,, to obtain an X-yagi antenna with a gain of 25dBi directivity, you must have at least 25 X-elements...!!!
-
,,,not,only 9,1 --9,5dBi... ,,, for a wider band of frequencies, a director element can be added...
-
,,, if this cover liver pate is cut in the three sides, you can get a good antenna panel for 3G...

,,,this it"s>>.https://www.jampro.com/uhf-tv-panel-antennas/

I don't think so, however, it is important for the coaxial cable to be on the center of the spiral. still try ...!!
-
Well, but this antenna is not in reality ... the coaxial cable comes inside the tube...!!!
-
I feel good about this ... can you put some pictures?
-
,,,, here in the forum you can find something with HFSS program but I do not use it, it is more complicated, although offers more programming accuracy compared to CST...!!! ,,, and programming with HFSS takes long time than CST...!!
-
I'm working on that now.,,,!!!!
-
,,, the antenna I think would look like this, slightly modified...
-
,,, yes, with this ...
-
I don't know, probably both...!!!

,,,welcome friend .... !! ,,,try to use the google translator for english...!!! ,,, yes, let's see what can be done considering that this type of antenna has been posted for a long time here...http://www.lan23.ru/forum/showthread.php?t=8107

Yes, but where did you get this from?
-
,,, and that would look like a simulation after Kraus...wl=157,78mm : F=1,9GHz ,,,and a panel antenna with 2x2 patches...
-
,,, the basic sketch for batwing antenna by various authors...wl=wavelength
-
,,,good work, but it's still to work....!!!!
-
In contrast to frequency domain tools, a transient solver’s performance can be degraded if the frequency range is chosen to be too small (the opposite is usually true for frequency domain solvers),,,,then transient analysis ...!!!!

,,,RG58U Low Loss Coaxial Cable

,,,aha,this it"s the sleeve flower pot, with UV protected PVC tape or heatshrink...!!! ,,,and the coils... ,,,the other...
-
,,,you make the copper wire spiral and then you extrude the faces in succession(with different materials and thicknesses)...!!! ,,,but the antenna looks great at 2.5m...!!!
-
Hi bro...!!!! I think I need more constructive details...!!! What kind of coaxial cable is used ... ??? Sleeves,what material is it? From where did you get this drawing...???
-
,,, so look for the 2.4GHz frequency...
-
I'm going to do a vertical polarization simulation.
