Forum: Questions Related to Antenna Theory   Posted: Thu Mar 22, 2018 2:19 am   Subject: Finding "Average Gain" within a beam
Hello, I have been working to find the total percentage of power which is contained within a beam. I've realized that I cannot simply use the peak value for Gain, and follow the rules for finding powe ...

Hello, it says in the "Dolph-Chebyshev Weights" section of the website, that all sidelobes should be equal in magnitude for a Chebyshev taper. I have heard that before, but in running some s ...

Forum: Questions Related to Antenna Theory   Posted: Fri Dec 29, 2017 5:40 pm   Subject: Converting 2D angles to solid angles
If I know the beamwidth of my main beam is 2 degrees in the azimuthal and 2 degrees in elevation, how can I determine what solid angle this would create? This article essentially says that the number ...

Forum: Questions Related to Antenna Theory   Posted: Thu Dec 28, 2017 2:00 am   Subject: Far field in arrays
Fair enough. Maybe I should just re-phrase the problem. I am trying to perform calculations for power transfer efficiency / power density with the array I described before. The peak gain is 37.65 dBi ...

Forum: Questions Related to Antenna Theory   Posted: Wed Dec 27, 2017 9:04 pm   Subject: Far field in arrays
I'm doing a simulation at 5.8 GHz with an array with dimensions 2.4 meters by 2.1 meters. Based on what you're saying, I wouldn't be able to make any accurate far field calculations unless I was outsi ...

Forum: Questions Related to Antenna Theory   Posted: Tue Dec 26, 2017 3:43 pm   Subject: Far field in arrays
I know the far field condition is related to antenna dimension and wavelength, but I was wondering, what if you had an enormous array operating at say 2.4 GHz, where the wavelength is ~ 12 cm. Do you ...
