Antenna Official

These, like the whip antennas on walkie-talkies, send and receive signals in all directions equally. They are perfect for mobile devices that move around.

The physical design of an antenna is dictated by the it is meant to capture. This is why a car’s radio antenna is a long rod (for lower frequency, long waves), while the antenna inside a smartphone is a microscopic, complex trace on a circuit board (for high-frequency, short waves). Types and Evolution antenna

Antennas have evolved significantly since Guglielmo Marconi’s first transatlantic transmissions. These, like the whip antennas on walkie-talkies, send
