A Hertzian dipole is a specific type of antenna that operates under the principles of Hertzian wave theory. This theory describes waves in the form of oscillating electric and magnetic fields that propagate through space perpendicular to the direction of the wave's propagation.
Key characteristics of a Hertzian dipole:
It is a linear antenna, meaning that its direction of maximum radiation is fixed in space.
It is a half-wave dipole, meaning that its electric field reaches its maximum amplitude at the center of the antenna.
It is a resonant antenna, meaning that it has a specific frequency at which it operates at maximum efficiency.
It is used in various applications, including radio communication, radar, and wireless charging.
Examples:
A typical antenna used in radio communication is a dipole antenna.
Another example is the antenna on a microwave oven, which is also a dipole.
Some wireless charging devices use a dipole antenna to transmit and receive energy from a coil in the device
