,,,, yes, you're right, that's what I ask myself, why ... ??? !!!
-
Or maybe you want to say something like that.,,(dual frequency=814MHz-2442MHz) ,,,or something like this...
-
This yagi antenna it pretty simple to execute, but it is worth making an adapting loop still coping lambda / 2,by a double plated pcb circuit
-
My simulation above is compliant...!!! How long is the coaxial cable ?, this is important ... !!!
-
,,,for this frequency band, I don't think it's possible...!!! ,,,maybe only a Vivaldi antenna....!!!
-
I know this, I solved it ... !!! ,,,here it"s the CST*file..... Pagoda 5.5.cst
-
,,, a first test with wire mesh, with 10mm mesh( without reflector)... ,,,with reflector...
-
I don't know, but the results of this Pagoda antenna are not eloquent or maybe I'm wrong somewhere,,,,
-
,,,hi buddy...!!! I do not have the dimensions of this antenna, but I will try to improvise one...!!! I think it is such an antenna...
-
,,,hi buddy...!!! ,,, you have the antenna pagoda .. ???
-
oooo, you're right, sorry...!!!! ,,,then ,so to be it...
-
,,, that could be .... ??? !!!

A Notch Filter is also known as a Band Stop filter or Band Reject Filter. These filters reject/attenuate signals in a specific frequency band called the stop band frequency range and pass the signals above and below this band. For example, if a Notch Filter has a stop band frequency from 1200 MHz to 1300MHz, it will pass all signals from DC to 1200 MHz and above 1300 MHz. It will only block those signals from 1200 MHz to 1300 MHz.

,,,welcome back,my friend...!!! ,,,for you,I will try to simulate this notch filter....!!!
-
,,,yes,I"ll try...!!!
-
,,, of course it has importance, the lack of border, it alters the gain, the impedance as well as the front-back ratio of the antenna...!!!
-
,,okay my friend,let me see what this is about Messages...!!!
-
,,,hi buddy...!!! ,,,what message are you talking about..??? ,,, I'm trying to simulate this....
-
I think a parabolic reflector would be better....!!!!
-
Yes, Aurel, it is, I think I will try to simulate this Yagi...!!!
-
",,,, it would seem that this yagi-antenna is better....https://www.youtube.com/watch?v=HwMsUICo8jc&t=31s

,,, the antenna dimensions with adapting lines ....

,,, a simulation attempt... ,,,but without this line of adaptation....
