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.

Active satellites are equipped with their own power source and are capable of generating and transmitting signals, whereas passive satellites rely on reflecting or enhancing signals sent from Earth. An example of an active satellite is a communication satellite that amplifies and retransmits signals, while an example of a passive satellite is a GPS satellite that reflects signals back to Earth for navigation purposes.

== == "English grammer active and passive voice change from active to passive .
The passive voice must have the verb 'to be' in the correct tense plus the past participle of the main verb. Here are some examples: I do (active)/it is done (passive) I did (active)/it was done (passive) I am doing (active)/it is being done (passive) I was doing (active)/it was being done (passive) and so on So to change protect into the passive would be I protect (active)/ It is protected (passive)
An active satellite has its own power source to transmit signals, while a passive satellite reflects signals back to Earth. Active satellites can amplify and process signals, making them more efficient in communication. Passive satellites are simpler in design and are often used for tasks like Earth observation.
