,,,hi buddy...!!! ,,, yes, it is possible, but you have to wait a little longer until I do a simulation for this frequency...!!!

Universal external antenna AX-2014P 2x2 MIMO is intended for use in complete equipment of wireless data transmission systems standards: 2G(EDGE, GPRS frequencies GSM1800) 3G (UMTS 2100) 4G (WIMAX, LTE1800, LTE2600) Electrical characteristics Operating frequency range, MHz 1700-2180 Gain, dBi 13-15 The width of the days in H-plane, degrees 30-45 Days width in E-plane, degrees 30-45 The sidelobe level, dB, not more -12 Isolation between channels, dB, not less 28 Input impedance, Ohm 50 SWR in the frequency range, not more 1,5 Permissible power watts 50 Polarization vertical+horizontal or slant +/-45 degrees Mechanical characteristics Weight with mount, g 1080 Overall dimensions without mounting, m 0,24х0,24х0,05 Connector- 2 x N-female The material of the radiator -galvanized steel Material of protective box-Polycarbonate+ABS Operating temperature range-from -60°C to +80°C Mechanical characteristics Weight with mount, g 1080 Overall dimensions without mounting, m 0,24х0,24х0,05 Connector 2 x N-female The material of the radiator galvanized steel Material of protective box Polycarbonate+ABS Operating temperature range from -60°C to +80°C -transmission line -piece A -piece B

I was looking for a design that promised reasonable gain without excessive size. The short backfire antenna is not a common antenna, promised 20dBi and looked easy to build. Several designs were found and analysed which did reveal a few discrepancies which seem now that been resolved. A quick look at the finished antenna shows a 'cake tin' style base fed with a elliptical patch as vibrator and a waveguide as sub-reflector.

As it turned out, this is an ordinary getinax (who else calls textolite), on which the same Board is etched as a vibrator, and as a reflector and the back cover - a stainless plate. Getinax thickness is 1 mm, the distance between the vibrator and the reflector is 10 mm. Dimensions are attached (sorry for the quality, quickly made in paint-e). Very easy to repeat, anti-crisis solution . The gain factor was compared with the same 17dBi grid, which was slightly lower than the stated value . Most likely, they are made in Ukraine, although Poland is listed as the manufacturer. If anyone has heard anything about their production , we will share our knowledge .

1) Operating frequency: 1090 ± 15MHz 2) Passive gain: 2dBi (dipole antenna) 3) Antenna polarization: Omni-directional vertical linear polarization 4) Active gain: 20dB 5) deviation from the external range: >30 dB 6) Working voltage: 2.5-5.5 V (negative core only) 7) Working current: 80mA 8) System resistance: 50 ohms 9) Antenna weight: 15g 10) Dimensions: 20 × 170 mm 11) Connector shape: SMA standard female head (outer inner screw hole)

,,, such an option for double batwing would be interesting...!!!!

,,,it would be nice if you could show through a tutorial how to do an optimization and run faster in CST Microwave Studio...!!!

,, what computer do you have (or laptop) .. ???

,,, bravo, you are a great doctor ... !!!

The KROKS KAA20-1700/2700 BOX MIMO panel antenna is designed for use in conjunction with 3G / 4G modems, in the frequency range 1700-2700 MHz. The antenna is compatible with equipment for the following standards:: 2G (EDGE, GPRS on GSM1800 frequencies) 3G (UMTS 2100) 4G (LTE1800, LTE2600) 2.4 GHz WI-FI (IEEE 802.11 b, g, n) Dimensions (length, width, height), mm 440 x 435 x 105 Package dimensions (length, width, height), mm 445 x 440 x 110 Package weight, grams 3900 Antennas-characteristics : Operating frequency range, MHz 1700-2700 Antenna gain, dB 17-20 SWR in the operating frequency range, max. 1.8 Polarisation ,Linear Wave resistance, Ohms 50 (SMA connector) Maximum input power, W 10 Connector, SMA-female Operating temperature range, oC -40 … +50 Maximum permissible air humidity, % 100 Port decoupling at least, dB 35

,,, and for the 1800MHz frequency... 1800rect-patch.cst

,,,an antenna with square elements cut corners...

,,,for which this antenna must be placed at a height and not have obstacles in front ... !!!!

The BAS-2346 FLAT MINI MIMO antenna is designed for equipment operating in the frequency range of 690-960 MHz / 1800-3600 MHz and having ports for connecting external antennas with MiMo support (Multi input multi output) The antenna is connected by two 5-meter-long RG-58A/U cables with SMA connectors. If necessary, the cable can be extended in the same way as the wave one with a resistance of 50 Ohms. You may need an SMA-CRC9 adapter (TS9, FME, etc.) to connect to the hardware.Adapters and an additional cable are purchased separately. The antenna can be mounted on a mast with a diameter of 20 mm to 50 mm or on a wall bracket. A distinctive feature is the extended frequency range, including 3.5 GHz. The location of the antenna:Outer Supported communication standards:GSM (GPRS/EDGE), 3G (HSPA/HSPA+/WCDMA), 4G (LTE800, LTE1800 LTE2700, WiMax) Operating frequencies, MHz:690-960 MHz / 1700-2700 MHz /3400-3600 MHz Gain factor, max., dBi:7dB / 12dB / 7dB The standing wave ratio on voltage not more than:1.5 Wave resistance, Ohms:50 Cable length, m:5 Connector type:2 x SMA Overall dimensions (without mounting unit), mm:160x170x75 Weight, not more than, kg:1 Package dimensions, mm:175x215x100 Package weight, kg:1.1

These are the dimensions for a Yagi antenna with 6 elements and linear dipole CFO-FZo A3 CFO-VZo

,,, this antenna is one of the best, I wonder why it doesn't work for you...!!!!??? ,,,, with 2x2 such antennas I don't think it has a gain of 21dBi but only 18 dBi....

I also need these dimensions ... !!!

,,, try to open the antenna panel, there may be something wrong inside or check the coaxial cable and the connections with the sma plugs...!!! ... could you show the inside of the antenna ... ??? !!!

I have tried many times to make a simulation at this antenna but I was never satisfied with its results. So I made a change to it, and I got some good results, especially with regard to the frequency bandwidth
