,,, congratulations doctor, but I think you need to work a little on the impedance, it should cover a wider band of frequencies...!!!

,,, it could be something like this ....

,,, yes, I think it could be ... !!!

Dimensions; vibrator = 129x129 mm; reflector = 168x168 mm

,,, it is recommended to show all dimensions...!!!

,, is one and the same with antenna ,,, copper sheet or galvanized sheet...!!!

,,,hi buddy...!!! ,,, but I think it's better that way ... !!!!

,,, it might work, but the isolation between ports leaves much to be desired, it must be tried ... !!!

,,, and Dr. Pepper says.... When the PDF is a scientific article I have perhaps access Edit: here it is: wong2004.pdf

,,, it seems that the impedance is not very good ,, okay, okay, it also shows the dimensions .... !!!!

,,, this is what the 0.35mm thick sheet looks like...

,,, I will do a simulation for PCB 1.6mm thick as well as for antenna only 0.35mm thick sheet...!!!!

1) No. 2) Other dimensions are required for 0.35mm copper sheet. 3)The antenna simulated by me , works just as well for the 5.0-5.5 GHz frequency range.

,,, that would be ... !!!!

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

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 ... !!!
