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.

-
UMTS-FDD frequency bands and channel bandwidths(3G) 1920 – 1980 MHz---Uplink 2110 – 2170 MHz---Downlink Fm=2045 MHz ,,,that's it...!!! ,,,it seems that this antenna does not ensure the bandwidth frequency required...!!!! ,,,it is the narrow band...!!!
-
The length of the wire must be about 90 + 2 + 2 = 94mm
-
I will try to do it...!!!
-
-
I think it is possible, and it increases the gain to 18-19dBi...!!!
-
,,,it's normal to have a slightly worse result, it does not have 4patches...!!! ,,,the dielectric changes its dimensions and has little influence. I will try to make such an antenna with 4patches.
