Hi, Gurus,
Supposed there is a lens antenna with radius 15mm, what is the focus area size for the lens?
I will put a microstrip patch antenna in the area, so I want to the size to limit the patch.
And now I have a patch with 2.4mm*7mm, is it too large for the lens?
If I use the 2.4mm*7mm, except the gain variation, any other thing need to be considered? such as phase etc.
Sincerely,
Tony Liu
I think the size of the focus area should depend on frequency and other properties of the lens. It's probably best to extract the size from simulation.
The answer depends on what properties you need. For a symmetric, narrow beam, the red curve is "better", yes. If you simply need more gain at/near broadside, then the other option would be "better".
