,,, in the air with dielectric spacer supports in the center of the patch...!!!

,,,hi buddy...!!! ,,,as far as I understand , you want to use a Cassegrain Offset with this double patch antenna...!!! ,,,something like that ... !!!

Instrumental,Bester antennas made after this program (Cantennator), are not very good...!!!!

,,,this works too...!!!

,,,0.5mm or 1mm, it doesn't matter...!!!

,,, to obtain the 75 ohm impedance at connector F, it is necessary to use the 2.8mm diameter pin...

,,, in my picture above, I mistakenly passed the SMA connector, when in fact it is an F connector...!!!

Efficient offset mirror antenna irradiator for 4G networks (LTE800 and UMTS900, with support for MIMO technology. F=790-960 MHz, Resulting CU with a reflector up to 25dBi. The connector type is N-female (50 Ohms). The maximum speed of data reception in the LTE800 at a distance of up to 30 km.

Mishka,try to design a log-periodic antenna as above (Kroks KNA+ 800-2700 MHz)

I managed to do an optimization for you(75 Ohm impedance)...

,,, yes, it is necessary to position two antennas at 45 degrees with a distance between them of approx. 0.9 * lambda..!!! ,,, a single MiMo antenna does not have the two ports isolated...!!! ,,,the above antenna is not well sized...!!!

,,,okay,then you see that too....https://www.lan23.ru/forum/node/10557

,,, why don't you try to make this type of antenna, better ... !!!

Is also an interesting antenna... now it must to make another slightly less in material cost and in my opinion more technologically advanced broadband (400...450MHz) In beam - Plast. pipe Ø25mm . elements- the same copper wire 4.6 mm ....

The proposed antenna is comprised of 2X4 perfectly electrically conducting (PEC) plates that are connected to the two edges of a rectangular PEC plate which is horizontal to the ground plane, as shown in Figure . The configuration mimics the shape of a butterfly. In general, the two PEC plates – two wings of the butterfly – can be circular, elliptical, or any shapes for impedance matching purpose. The antenna is implemented at a height h above the ground plane. In order to achieve the good impedance matching and desired radiation patterns, the angle alfa(11 degree) between the wing and the z-axis can be varied. The feed point of the antenna is located at its rectangular plate by a coaxial probe through a SubMiniature version a (SMA) connector.

,,, I don't think that's it ... !! 7x8 patches...???

,,, beautiful work, congratulations .... !!! ,,,how you made the connection between the elements...???

,,,yes, it's something like that...

,,,show the vibrator...!!!

,,, well, then let me do another simulation with optimizations...!!!!

,,, okay, but you have to tell me what kind of box-can you have (what dimensions are close to the one I exposed)...!!!

,,, changing the power lines of the Petra BB 75 Ohm antenna...
