Beautiful work, how did you adapt to 50 ohm...??!!!

It looks like that this type of antenna does not really work too good... ", with these dimensions ...

Another dipole antenna version with parabolic reflector... ,,,or so....

,,,and a helix much simpler...

For example 5 elementno Yagi half a meter in length. The same band, the gain will be higher forward, and the suppression ago.

,,,simpler.... Detail...

simpler...

,,,for what...?? it does not matter ... !!! I'm going to make a simulation of that antenna...!!!

"with all the excuses, but this one MiMo-patches. is not the best...~~~~!!! ", it's something for stupid stupid people !!! !!! ...best. try everything else ...!!!

It"s suitable for anything...!!!

I do not understand what you mean by that ...!!!

I am thinking about making a simple dipole yagi to try some longer range 5.8ghz survey style flying .., without reflector... ,,,with reflector...

,,,or so...

But I think this yagi-biquad should be tried as well...

,,, and here's a wonderful practical achievement of our assiduous collaborator, TommyD ... ", and related simulations ...

I thought this miniature antenna in the sense of its execution by a simple turning operation in a few pieces (4) The vibrator(1) is made of copper, the rest of the elements(3) are made of duralumin. This patch-yagi antenna has a circular polarization... These are the dimensions of the antenna...

,,,no,,,0,5mm...but if you want I turn it into 1 mm

These are the results...

When I have time, I will do a simulation on this antenna ... !!! ,,, but tell me the dimensions of the square adapter .... !!! ,,,this...

is an Interesting idea, which could cause a real revolution in the world of television – a project of Aereo. Startups Kanojia Chet (Chet Kanojia) has developed the world's first technology with which users could watch all the channels and terrestrial transmission for free on their mobile gadgets through the Internet. Technology Aereo involved the presence of small antennas, which catch the signal, recorded them on a computer hard drive or phone memory. Based on this innovation, I tried to make a simulation with this antenna on the PCB,,,

,,,thanks buddy...!!!

,,,it"s important the distance between patches and the reflector....!!! which are ...?

The gamma match is often used for providing Yagi impedance matching. It is relatively simple to implement. As seen in the figure below, the outer of the coax feeder is connected to the centre of the driven element of the Yagi antenna where the voltage is zero. As a result of the fact that the voltage is zero, the driven element may also be connected directly to a metal boom at this point without any loss of performance. The inner conductor of the coax is then taken to a point further out on the driven element - it is taken to a tap point to provide the correct match. Any inductance is tuned out using the series capacitor. When adjusting the RF antenna design, both the variable capacitor and the point at which the arm contacts the driven element are adjusted. Once a value has been ascertained for the variable capacitor, its value can be measured and a fixed component inserted if required.
