Me ganaste loco , el mio es de 2020...LMAO! WHICH ONE you need...? The LPDA you open the 2D DXF (just one) make it double Asign thickness of the material you want (one over the other) and then add a BRIDGE (rectangle sheet at the END , Wide part) You need an STL from CST and it would open as ALL SOLIDS not materials (dielectric , pec ,etc) designated...and then TWEAK IT...
-
WAY MORE REACTIVE than square...
-
Jomy did you try a conical (cilinder) Horn ?...(should be smoother all around) PS: the TEM UWB should have a new post...imho
-
I see it done with Brass sheet (rigid no need for dielectric support) OR copper Tape (0,0254 mm) over Polystyrene foam...
-
is that a BALUN...? looks like it...
-
Nice project (for UWB)...could you post the 3d (.stl .hfss or .aedt) to run it through cst up to 6ghz , and gain seems to go all the WAY to the problematic zone (under 500mhz) nice for an SDR PS: I went with LPDA , cone elemwents...but NOT happy with the results...

RAM size 8 gb at least (ddr4 better) and Processor cores (8 would be best) are important...(CST mws before 2020 would require less resources) but I used it with 6gb of ram and 2 cores (intel is better) check the GPU acceleration capacity...(heavier than games) used gaming laptop maybe...

You are using a Circular polarized antenna and tryin to receive a VERTICAL polarized signal...NO GOOD...and shifted band frequency too... YOUR antenna should provide Vertical polarization and be centered at 920 MHZ with a Bandwidth of 80 MHZ (880-960) Yagi Vertical polarized...
-
RSSI (signal and Quality (packets received transmited) are too low...you need over 15 dbi at least ...try to make a big reflector (wire mesh , chicken coup wire...at least 1 m , put it in the back of your antenna) Router (waterproof) close by the antenna (losing signal on cables)

LiteVNA measurements

You use WHAT WORKS (that'll be DISCRETE PORT 1st and WAVE Port at the end) Same for Solver mesh settings
-
Face select inner+pet+shield+outer edge , then assign wave port (ALL of them should be leveled) puting a PORT on the END of an ANTENNA is a NO-NO

Still workin on it (good antennas BAD FEED NETWORKS !) I'll upload it if it works give me time After the simulation is OK on Port impedance Z (should be 50 ohms ) Electronics = Cables= Antennas (50Ohms=50Ohms=50ohms)
