and here are the results of the quasi-bowtie antenna... ,,,, by adding a reflector....!!!
-
,,,,yes, of course, but some dimensions have to be modified...!!!! ,,,, and I think you're right, a 75 ohm coaxial cable should be used and I think I'll make a simulation for this impedance ...!!!

Operating frequency range, 2350÷2650 MHz..

Panel antenna AX-2020P designed for use in set c 3G modems (routers). Antenna type – common-mode strip grating. Recommended for use at the boundaries of the service area, with a very weak and unstable the level of 3G signal and also in cases when it is necessary to use a large amount of cable between the antenna and the modem. Electrical characteristics Operating frequency range, MHz=1900÷2180 Gain, dBi=19-20 The width of the days in H-plane, degrees=6÷18 Days width in E-plane, degrees=16÷18 The sidelobe level, dB, not more=-13 The ratio of forward/back, dB=24 Input impedance, Ohm=50 SWR in the frequency range, not more=1,5 Permissible power watts=10 Polarization=vertical/horizontal/inclined Mechanical characteristics Weight with mount, g=3350 Overall dimensions without mounting, m=0,45х0,45х0,05 Connector=N-female Antenna material=steel, galvanized steel Protective coating=powder polymeric paint Material of protective box=ABS+polycarbonate

,,,yes ,it is for 650---950 MHz...!!!
-
,,, okay, I wish you success ... !!!
-
RC-Concepts,congratulations....!!!!
-
,, yes, you can ... !!!
-
,,,,the angle it"s 60 degree>..1!!
-
", yes, other directors can be added, but other simulations have to be done......!!!
-
By adding a dielectric rod waveguide (DRW) to the feed, it can increase the bandwidth of the frequency up to 3.5GHz,,,, ,,,your cantenna is different from mine..!!! ,,,, but you have to give me the dimensions to your cantenna...!!!
-
,,, antenna BDM-2 for 1800 MHz... ,,, constructive details....
-
-
,,, a good site about the antennas and not only ...http://sites.prenninger.com/elektronik/dvb-t-antennen/wifi-antenne
-
Unfortunately, you did nothing....!!!!
-
Not right now, but you can solve it yourself...!!!
-
Then do something like that....
-
-
,,, my friend, explain to me, what you want to do with this quarter wave transformer in CST...???!!!
-
,,, it can be used, but the dimensions will be totally different...!!!
-
,,, I don't think so, it's a PCB with a thickness of 0.33mm..!!!!

""" with the method shown above, you can delete the two ports...!!!
