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.

They are shapes.
They are all shapes!

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.

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...
it's reflectors.....
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.
They're both shapes... and three dimensional shapes.
They are both 3-dimensional shapes.
The main reflectors of solar energy include mirrors, shiny metal surfaces, and reflective films. These surfaces are designed to redirect and concentrate sunlight onto a specific target, such as a solar panel or thermal receiver, to enhance energy collection and conversion.

You can troubleshoot the power antenna on a Lincoln Mark VIII by first checking the fuse. A blown fuse is the most common reason for an antenna not working properly.
