d=52,5 mm>>>for 2,35 GHz d=54,3 dr=180 mm>>>for 2,35 GHz dr=186
-
Okay, but I need it for 2.35MHz. What is the diameter of the rings now? Yes, drop the file CST
-
Pupe, try a Strella-11 omni antenna too....!!! I think we still need to work on this...
-
Also available for sale are the more powerful Stella-8 and Stella-11 antennas with a gain of 8 dBi and 11 dBi, respectively. Communication Standard WIFI 2400 Frequency range, MHz 2400-2480 Gain factor, dB 11 Bottom width in the horizontal plane, deg 360 Bottom width in vertical plane, deg 9 Wave resistance, Ohms 50 SWR no more than 1,5 Weight, grams 1100 Dimensions, cm 100 x 8 x 6 RF connector N-Female

stella-5.cst
-
The stella-5 antenna made by Baltic operates in the 2400-2480 MHz band. the claimed gain is 5 dB. the diagram is circular. I tried to simulate the antenna in cst, but for some reason the resonance turned out to be shifted, all the dimensions were repeated exactly. I am attaching the project, and a photo of the SWR measured on the device

-
The shape of the main LOBE IIRC at -6 db affects efficiency...
-
-
,,,that's what it would be like... reflector diameter=180 mm
-
Yes, I didn't calculate the diameter correctly. I took the wavelength as the diameter, but I probably need the circumference.
-
,,,122 mm diameter.../// I don"t think so...!!! ///maybe 40,5mm iameter...!!!
-
The diameter of the rings is 122mm, the platinum is 122mm, but it is FR4 without metallization. Required frequency 2.35GHz Biquad.cst
-
,,,what is the diameter of the rings and plate...!!!
-
Recommend an omnidirectional, circularly polarized antenna with a gain of more than 8 dBi Would this option be suitable?
-
Yes, that was a mistake... I was multiplying the coefficient and I had to divide it)
-
,,,take this... parabola0,6.cst
-
Pupe changed their profile photo
-
of course there are flaws, the f parameter does not accurately display the distance between the antenna and the mirror, but I think that's not the problem with my poor results
-
I'm probably using the wrong formulas... the shape of the mirrors in your project and mine are very different. here is my calculation. the Kp value was 0.83 and 0.6 (surface utilization factor) 25dBi_2400MHz.cst
- Last week
-
,,,this is the simulation with your parabola(f/D=0,6)... and Efficiencies... And this is the antenna...
-
0.01 dB
-
antenna effeciency
-
No, this is not a general rule....what do you mean by efficiency coefficient...!!!...???
-
Does this rule apply to all parabolic antennas? And another question is about the efficiency coefficient and the utilization coefficient of the surface of the parabola. I chose both of these values for 0.9, but perhaps they should be changed... how are these parameters normalized?
-
Okay, thanks, I'll try to count it now!
