Dear all,(adsbygoogle = window.adsbygoogle || []).push({});

Let's assume that I have just bought the perfect omnidirectional antenna and I try to understand how the wavelengths are transmitted. If I got it right, there are wavelengths getting 'out' towards the 360 degrees directions.

Now let's assume that I have a perfect receiver antenna that it will only captures wavelengths that come from the 180 degrees exactly. So in theory only one wavelength will be captured.

In that ideal world of receiver and transmitter antenna, how I can find

a) How much energy this one wavelength will carry (assuming that I know how much energy was transmitted from the transmitter antenna)?

b) What are the 'dimensions' of this signal? I know the wavelength but how I can also find the height of it? In other words if I know wavelength and height I can define the area that this signal will occupy.

I would like to thank you in advance for your help.

(I need this kind of information to get some basic understanding what I am capturing)

Best Regards

Alex
