A car antenna booster is used to 'boost' the radio waves of the car's antenna. This is usually used to improve radio quality and reduce static that might be heard.
Any solenoid in your car is an electromagnetic device, including the alternator. The car antenna also receives electromagnetic waves to get radio.
A dish antenna must face the arriving waves.

It has bristles or sensers on the antenna. It depends on what bug.
Yes. A good rule of thumb is that if the device has an antenna, it uses radio waves. An antenna would not be needed if it didn't use radio waves.
For wireless communication systems, the antenna is one of the most critical components. A good design of the antenna can relax system requirements and improve overall system performance. An antenna is the system component that is designed to radiate or receive electromagnetic waves. In other words, the antenna is the electromagnetic transducer which is used to convert, in the transmitting mode, guided waves within a transmission line to radiated free-space waves or to convert, in the receiving mode, free-space waves to guided waves.
They are picked up by the antenna.

a radio telescope focuses the incoming radio waves on a antenna, which absorbs and transmits these waves to an amplifier, just like a radio antenna.
