Antennisignaaleista refers to signals transmitted or received by antennas. These signals are fundamental to wireless communication and span a wide range of frequencies and applications. In essence, an antenna acts as a transducer, converting electrical signals into electromagnetic waves for transmission, or conversely, converting incoming electromagnetic waves back into electrical signals for reception. The characteristics of these signals, such as their frequency, amplitude, and phase, carry the information being communicated.

Different types of antenna signals are used for various purposes. For instance, radio waves are used for broadcasting, mobile communication, and radar. Microwaves are employed in satellite communication, Wi-Fi, and radar systems. Infrared signals are utilized in remote controls and short-range wireless communication. The design and properties of an antenna are closely tied to the frequency of the signals it is intended to handle, ensuring efficient transmission and reception.

The quality of antenna signals is crucial for reliable communication. Factors like signal strength, interference from other sources, and attenuation due to distance or obstructions can degrade signal quality. Techniques such as modulation and demodulation are used to encode and decode information onto carrier waves, allowing for effective wireless transmission. Understanding antenna signals is key to comprehending the principles behind modern telecommunications and broadcasting technologies.
