,,,thanks....!!!

,,,hi buddy..!!! I didn't make much progress with this antenna, but I will be ready soon..!!! I try to see if the lids from the liver pate boxes can be used...!!!

,,, in X-polarization, they are lost, approx. 3 ... 5 db ,,, but you could try this option too.. !!!???
-
Bravo,,,!!!... and how it works .. ???
-
,,,Bejo, look what they did....!!!
-
,,,not yet...!!! ,,, but soon .. !!!
-
,,, the thickness of the material does not influence too much the frequency, the dimensions must be changed ... !!!!

„, these are the results with 0.2mm metal sheet...

This project want to cover all of the cell phone bands, WiFi and Bluetooth up to 6 GHz as well as the new UWB band from 5 GHz to 10 GHz with just one antenna installation.He did not want to maintain a dozen different antennas with multiple ranges and tuning; just one ultra wideband antenna. https://www.rtl-sdr.com/constructing-a-3d-printed-wideband-900-mhz-to-11-ghz-antenna/

,,,okay buddy,I will try,,,but tell me this antenna is on the PCB ... ??
-
,,,okay,I will try to do a cst modeling for you...!!!

I don't have this file anymore, but let's see what can be done...!!! yah,this it is.. 145+435mhz.cst

,,,cst...!!!
-
,,,yes...!!!
-
,,,see this... ,,, to obtain an X-yagi antenna with a gain of 25dBi directivity, you must have at least 25 X-elements...!!!
-
,,,not,only 9,1 --9,5dBi... ,,, for a wider band of frequencies, a director element can be added...
-
,,, if this cover liver pate is cut in the three sides, you can get a good antenna panel for 3G...

I don't think so, however, it is important for the coaxial cable to be on the center of the spiral. still try ...!!
