,,,this is the simulation with your parabola(f/D=0,6)... and Efficiencies... And this is the antenna...
-
0.01 dB
-
No, this is not a general rule....what do you mean by efficiency coefficient...!!!...???
-
,,,but f/D=0.,448 ,it must to be 0,6...!!!
-
I think it must be f/D=0,6 Did you get the antenna from this forum...???? What is the diameter of the parabola...???
-
,,,yes, it seems so, the antenna is narrow band...!!!
-
,,,yes...!!1
-
-
,,,a first simulation attempt, optimization follows...

Single band IEEE 802.11 a/n standard High gain patch antenna Frequency (MHz) : 5150-5825 Peak Gain (dBi) : 10.0 VSWR : 2.0 : 1 Dimension (mm) : 76 x 72 x 3.8 Connector : IPEX MHF I Cable Length (mm) : 50 (customized) It seems to work well on the 5.6 GHz frequency.
-
A new attempt at impedance equalization... ,,,and some other dimensions...
-
Clanon,could you give some dimensions?
-
,,, another version of Bester Antenna by Alexander Bars.... and positioning this antenna in the focus of an offset parabolic dish
-
Another combination...

Loop yagis are basically a hybrid design of a tuned loop in a yagi type array. The best material to use for the construction of a loop yagi is brass, or copper. Brass is the better choice since it is easier to solder and corrodes less than copper. An example of a loopyagi in use. The antenna is on it's side so that the polarisation is vertical.
