Hello everybody :)
This is my first post! I have a mystery about radio communication that I was wondering about for a long time:
If I have understood correctly, most computers have a single WiFi antenna in the shape of a rod, which is placed in a particular orientation. My question is this: why does the WiFi signal strength seem to be unaffected by the orientation of the antenna even though the voltage induced will depend on the direction and polarisation of the WiFi radio waves? For example, my laptop (as far as I know) has a single antenna in the plane of the keyboard, and if I rotate my computer through many angles, my signal strength is unaltered.
Could it be that there are multiple (maybe 3) radio receivers that are positioned perpendicular to each other for optimum radio wave capture? Or maybe the router has 3 perpendicular transmitters?
Thanks a lot for your help!
