A lot of parabolic reflectors are used in antennas, particularly with frequencies in the microwave region. There are a few other shapes, but they are infrequent choices for antenna designers.

What is a directional antenna in a LAN?
Directional antennas work a bit like the reflectors behing the bulbs in flashlights, shaping the beam to go mostly in one direction. You get better performance that way, assuming you can keep the antenna pointing in the right way.

How many directors and reflectors in Yagi Uda antenna?
yagi udda antenna has only one reflector...but it has many directors...depending upon gain and efficiency...the length of reflector is normally...more than one-half of wavelength... and directors have a length less than one-half of wavelength...

They are both 3-dimensional shapes.
Are Passive reflectors used in both Active and passive Satellite system?
Yes. The most common antenna for satellite systems is the 'Dish'.The dish is a parabolic , passive, reflector.It merely reflects and concentrates the signal to the LNB receiver.Transmission also works this way, bouncing the signal off the dish, to concentrate it in one direction, in a narrow beam.
What are the main reflectors of solar energy?
Clouds are the main reflectors of solar energy.
