Antenna sizes are proportional to wavelength of EM wave. So higher frequency implies shorter wavelength . So size of antenna on satellite would be compact. Also the frequency used should have energy such that it’s not absorbed in any layers of atmosphere (energy should be lower than bandgap of material).
Read moreWhat type of signals are used in satellite communications?
Satellites communicate by using radio waves to send signals to the antennas on the Earth. The antennas then capture those signals and process the information coming from those signals.
Read moreWhich of the following mode has been used in satellite communication?
Satellite communication is an example of the broadcast mode of communication.
Read moreWhich modulation is used in satellite communication Mcq?
Digital modulation techniques are used in the satellite communication system, because.
Read moreWhy do satellites use microwaves to communicate?
Mobile phones communicate to a mobile cell tower using radio waves, towers communicate with satellites using microwaves. Microwaves are used as they can pass through the atmosphere . This signal can be sent to a satellite and used to communicate around the world (more than one satellite is required for this).
Read moreWhat is Ku band frequency?
Ku-band (12–18 GHz )
Read moreWhy Ku band is used in DTH?
These are some of the advantages of choosing Ku-band: because of its higher power , Ku band satellites (vary in size from 2′ to 5′ in diameter) are generally smaller than C band satellites. the power of uplinks and downlinks can be increased as needed. users with a C-band system in place can retrofit for Ku-band use.25 Kas 2019
