how to focus 10.525 GHz micro waves of low power of 10mW
(OP)
how we can make a pencil beam of microwaves generated from a microwave generator.
generator is not a magnetron but a microwave motion sensor.
please give me some technical information about it.

But, this is the extent of my knowledge in this area.

A quick "crude" bench example can be done with a horn antenna and a plastic bottle of motor oil. Move the bottle back and forth a few inches outside the opening of the horn, and you can point where the beam is greatly narrowed. Maybe "crude" is a bad pun for a dielectric lens made from a bottle of oil, but I once saw it demonstrated very effectively. The difference in the velocity of propagation due the the dielectric focuses the wavefront into a more narrow beam.
Using an example of ultrasonics from nature, dolphins and some small whales use ultrasonic sound to "see" underwater. To get a narrow aperture, their bodies have a mass of fat in their heads with a different acoustic impedance to focus the ultrasonic sound. Basically a dielectric lens in the ultrasonic domain.

Not really applicable to the OP's question, but still quite interesting I think.
