for 1.3GHz it is recommended to use elliptical cut
-
"And these are the latest results
-
-
For this, I have to resume the simulation, this project is old for a few years
-
You could say it's a new form of the antenna gain in a reasonable direction ...
-
then multiplies the dimensions of the image with k = 1,0345 for the frequency of 5,8ghz
-
But biquad2.igs file is for 1.5mm FR4 thickness,,,,!!!!!
-
What frequency do you want?
-
Ant_kid, are you interested in antennas for drones?
-
... yes. can adjust the impedance or something like that,,,,
-
the uplink and dowlink it should be roughly the same...
-
which antenna?
-
What dimensions did you use for FR4 thick 1mm ,,, ??? I have not posted such dimensions....!!!
-
,,,if CP is Circular Polarisation,,,,YES...!!!!
-
,,, for 1200MHz,don"t you think that the antenna is too big, about 4,8 times...???
-
Something like that ...???
-
,,,and here is a patch-yagi antenna made only from tin cans....
-
this means; the efficiency of an antenna is a ratio of the power delivered to the antenna relative to the power radiated from the antenna. A high efficiency antenna has most of the power present at the antenna's input radiated away. A low efficiency antenna has most of the power absorbed as losses within the antenna, or reflected away due to impedance mismatch. the efficiencies; -radiation efficiencies(magnitude in dB) -total efficiencies(magnitude in dB) -gain(in dBi)
-
"I do not know exactly, I think 59mm, but the simulation should be done
-
Yes,,,!!!
-
and here are the results for the frequency band 2500-2620MHz
-
только для образца .. !!!
-
-
круговые диски более эффективны
-
да, конечно
