wrong...!!

,,,may be 165x55mm...!!!

,,,from where 31x90mm?

Antenna for Small UAV by Nikita M. Boev Explanation of antenna choice for small UAV (Unmanned Aerial Vehicle) and its realization are presented. The suggested antenna has a simple construction with low weight and small size. It is operating in 2.4 GHz band. Radiation pattern is toroidal that allows to have a stabilized link at all directions to aircraft. Antenna is short-circuited for protecting from electrostatic discharge. ,,,and here is the simulation...

I told you, I do not have this ...!!!

Dimensions: 36.7 x 6.3 x 4.1 cm

No, I do not have the dimensions at this antenna ... !!

"Well, here's a variation of the antenna sector with expanded polystyrene spacers and flat-line transmission line...

If you have the pleasure, why not look on this forum ??? ..

"No, because it does not have a good isolation between the ports...!!!

After several simulations, I have reached a diameter of 0.8mm copper wire...

Okay,then try a cooper wire 1....1,2mm or 1,6mm,it must to do a simulation...!!!

,,,yes buddy...!!!

What, is it hard to cut a sheet of wire ... ???

,,,and the required dimensions...

,,,,good, and yet it seems to be broadband...!!!

,,, you can not, how as crossing the adaptation line, the potential null point ... ??? !!! ,,,or something of that kind...

" be careful ... vibrator size = 53mmx56mm directory size = 48mmx60mm

,,,these are the dimensions ... !!!

,,,good, I do not think this problem influences too much....!!! ,,,what displacement has the nut...???

Our Bejonet user says ... ""hi friend, i was made it, but still not good, unlucky me i dont have any instrument for check if this antenna is working or not, just try to connected to my router and wifi signal is not good.."" "and still I do not understand what the problem is ... !!! ???

,,,okay my friend, but not today...!!!

General information Panel antenna AH-2513P 2x2 MIMO is intended for use in the set of user equipment wireless communication systems LTE, WIMAX 2.6 GHz band. AH-2513P MIMO 2x2 antenna is the medium directional and recommended for application not far from the base station and in the city. Thanks to the support antenna MIMO 2x2, the speed of transmission when using modems LTE2600 (YOTA ONE, Huawei E392, Е3276, M100-4, etc) can reach 150MB/s. Electrical characteristics AX-2513PF MIMO 2x2 Operating frequency range, MHz 2500-2700 Gain, dBi 13 x 2 The width of the days in a horizontal / vertical plane, degrees 54/28 The sidelobe level is not more -13 dB Isolation between ports, not less >28 dB Input impedance, Ohm 75 SWR in the frequency range, not more 1,6 Permissible power watts 10 Polarization +45°/-45° (X-pol) Mechanical characteristics Weight with mount, g 1050 Mount-the mast diameter 20-52mm Range of working temperatures,C. Celsius -45....+60 Overall dimensions without mounting, m 0,2x0,2x0,04 Allowable wind speed, m/sec 35 Connector 2хF-female The material of the protective casing -Polycarbonate+ABS Antenna material -galvanized steel Fastener material steel Protective coating powder polymeric paint Dignity antenna AH-2513P MIMO 2x2: The tilt of the antenna polarization +45/-45 degrees. This solution allows to maximize the use of modern high-speed 4G LTE modems. Active radiators of the antenna are securely protected from rain body ultrafioletowego plastic. The inputs of the antenna closed-loop DC current between the outer and inner conductors, which reduces the probability of accumulation of static electricity on the modem input and makes optional the use of gazorazryadnoi Use SMA-male allows the use of standard antenna adapters (2 PCs) to connect the antenna and modem. The presence in the antenna of the two radiating systems with orthogonal polarization allows to work in mode MIMO 2x2 technology or implement Diversity.

Another way to connect the SMA port...
