Discone Antenna for GSM/3G/4G

[Admin 2421]

Here is another DIY antenna, this time for GSM/3G/4G usage. The design was calculated for 800-2100MHz and works well in this range. The antenna has a very broad bandwidth with a low gain and can be used for any application within the frequency range. Since the results are very good even up to 3GHz the antenna is also useful for WiFi. As well as ADS-B (flight radar) because 1090MHz is covered too. In general an excellent antenna for rtl-sdr operations.

Based on this calculator.

Hello aurel,
Thanks for posting.
The idea of a SW fractal loop antenna has fascinated me for years but seemed complex to implement.
I am very interested in your plan

SW fractal loop antenna

I am not sure ...what is SW fractal loop antenna ???

[Admin 2421]

,,,he probably refers to it, but anyway. must open another topic...!!!

Need correction on cone height, it can't be 90mm.

 

[Admin 2421]

,,,h =90mm ; (D-d)/2=(108,92-5)/2=51,96mm

,,,but I think it would be best with an angle of 33 degrees...!!!
