QO-100 Patch Antenna illumination angle

dl2kp · Jan 25th 2023

Hi,

to calculate the illumination of my dish, I need the radiation field of the patch antenna. According to the discription by G0MJW in Dubus2/2019 the dish was recalculated with sonnet light software. Unfortunately, sonnet does not show neither the -10dB-illumination angle of the feed nor the radiation pattern. There are lot of publications on the patch antenna, but nothing about the radiation. Does anybody know how to calculate the illumination angle of a patch feed with a free available software?

Hi,

now I found the necessary information here in the forum. See posting: "Cmoputer Analysis of dual band dish feed (G0MJW,.....).

I have posted POTY radiation pattern measurement results in this thread.

Take a look at post #36.

How can I find your post #36? I don´t see a possibility to search for post #36. What is the title?
