How to Measure Antenna Radiation Pattern Using Signal Generator

[@shyamalajudith7700]

Nice, now only I know how it works in measurement. Because my University no has such tools, only can view in simulation but do not know how to perform measurement. Thank you so much !!!👍👍👍

Gald it helps. 🙌

very well explained

Amazing video thanks a lot bro, we need videos like this.

do you have a calibration with external VNA?

[@LYSStuff]

What do you mean external VNA?

What will be changed in the case of LPDA Antenna? Will same setup work? And what about 2D Array?

[@LYSStuff]

Hi, nthg have to change, same setup will works. The graph plotted is 2D, what do you mean 2D array? You may refer to this few video for better understanding, it same concept of LPDA antenna (directional antenna) kzbin.info/www/bejne/n4rYdpprrtilnJI kzbin.info/www/bejne/oHvZkp6nf9F4q82cttps://kzbin.info/www/bejne/maGTlZWggpJ6nbM kzbin.info/www/bejne/maGTlZWggpJ6nbM Hope it helps.

If transmit antenna side is spun instead, the result pattern will be the same?

[@LYSStuff]

If both antenna is dipole and measuring omnidirectional, then yes. Normal pratice only receiver antenna is rotating.. But you also can only rotate transmitter antenna, and left the receiver antenna stay static.

how to calibrate the entire system for every power levels in your test setup?

[@LYSStuff]

For the power level calibration, just need to calibrate once, the step is adjust each power and save it in excel file, then load into the software. The radpat also have function to perform this calibration with step and automatic save into the software. You may refer to the video description to download the lab module sample from dream catcher, inside have shown the step of calibration. If using VNA for radiation pattern, only need to do normal calibration for coaxial cable, you may refer to this video using VNA to measure antenna radiation pattern. kzbin.info/www/bejne/n4rYdpprrtilnJIsi=LlBn3-0nvCKCT9er

@@LYSStuff Could you show how to measure 3D radiation pattern for the setup in the link you provided?

[@LYSStuff]

@@superdtp1630 I do not have the 3D radiation pattern training kits... The concept is the same, just need to do additional vertical 360 degree turn

[@superdtp1630]

@@LYSStuff I am new here so what is 3D radiation pattern training kits comparing to the training kits you used in your demo video?

[@LYSStuff]

@@superdtp1630 just extra vertical rotation, the training kit that used is only horizontal, so only can measure 2D radiation pattern.

Is the RADPAT v4.2 software free download?

[@LYSStuff]

Is an free software without license require, but it come together with the Dream catcher courseware, you may refer to the description link

[@superdtp1630]

@@LYSStuff Can i use the free software without the Dream catcher courseware?

[@LYSStuff]

@superdtp1630 you can use the software. But it can't detect any hardware, if no using the Dream catcher training kit

[@superdtp1630]

@@LYSStuff do you have video that shows how to download radpat v4.2 software?

Hi, This need request from Dreamcatcher. You can contact dream catcher.
