Radio waves, like all other waveforms in the electromagnetic spectrum travel at what is known as the speed of light. i.e. 3x10 to the power 8 metres per second (300,000,000)
but the distance between the earth and mars varies enormously depending on their relative positions in their orbits around the sun. Anything from approx 35 million miles at it's nearest to about 340 million miles or thereabouts at it's furthest.
So roughly 3 minutes minimum to about 30 minutes maximum.
Radio waves travel "at the speed of light" which, though very fast, is still a finite speed. Mars is far away so it takes 7 minutes for the radio waves to travel the distance from Curiosity to the Mars orbiter that then relays radio communications to Earth. How much delay in the electronics of the relay station in the orbiter and the electronics on Earth I cannot be certain, but certainly a measurable amount though probably less than a few seconds.
Shorter wavelength, higher frequency.
light travels at approximately 300,000,000 m/s, so to pass 7.5*1010 meters it would take: 7.5*1010/300,000,000=250 seconds = 4.167 minutes P.S. Mars is not that close, in real life the signal takes about ten minutes to travel either way.
Circular polarization characteristics of a helical antenna help offset the effects of spin modulation from satellites in motion, that is, the tendency for satellites to spin causing the position of their antennae to change rapidly in accordance with the spin, causing a fluctuation in the signal as received by a fixed signal on earth. Circular polarization of the earth fixed antenna reduces the fluctuating effects of the satellite's spin on the recived signal.

It would take 100 Earth years for a signal to travel from a star located 100 light years away to reach Earth.

The speed of a satellite signal is approximately the speed of light, which is about 299,792 kilometers per second. This means that signals transmitted from a satellite to Earth or vice versa travel at this high speed.
It takes about 3 minutes for a signal to travel from Earth to Mars when the planets are at their closest point. This means it would take approximately 6 minutes for the spacecraft to receive your command and respond back to you.
The time it takes for a radio signal to travel from Earth to the moon and back can be calculated using the formula: Time = Distance / Speed of Light. The speed of light is about 299,792 kilometers per second. So, Time = (382,000,000 * 2) / 299,792 = 508.8 seconds. Therefore, it takes approximately 508.8 seconds for a radio signal to reach the moon and return to Earth.
Radio waves can travel 300,000km per second. If someone was dialing from the moon to the earth, a signal would arrive in about 1.3seconds. The distance from the moon to the earth is 390,000km.
It takes about 1 hour and 24 minutes for a radio signal to travel from Earth to Saturn when the two planets are at their closest point. This distance can vary depending on the positions of the two planets in their orbits.
It would take approximately 3 seconds for a radio signal to travel from Earth to a spacecraft that is 900 million meters away. This is because radio waves travel at the speed of light, which is approximately 300 million meters per second.
You can approximate Earth's orbit as a circle, and therefore use the formula for the circumference of a circle. The radius is the distance Sun-Earth (150 million kilometers).
radio signal bents around the curvature of earth and hence travel longer distance than the line of sight signal. At ultra high frequencies signal follows the line of sight path and hence maximum communication distance is limited due to curvature of earth for given height of transmitting and receiving antenna
