How Do Radio Transmission Antennas Work?

Описание: You flip on the radio, and a voice crackles through the air—no wires, no connection—just pure wireless magic. But how does this miracle happen? In this episode of History of Simple Things, we decode the hidden world of radio transmission antennas. From towering steel giants broadcasting across cities to micro-antennas embedded in smartphones, discover how these unassuming devices power everything from AM/FM radio to 5G, satellite comms, and beyond.

We dive into the electromagnetic magic, the engineering marvels, and the modulation methods that make wireless communication possible. Whether you're a tech lover, radio enthusiast, or just curious how your voice assistant hears you—this is the story behind the signal.
