The whip antenna is the most common example of an antenna, a single
drive element and a ground plane antenna.

The whip antenna is a hard and soft wire mounted, usually vertical,
with one end close to the ground plane.
The whip antenna can also be referred to as a half dipole antenna.

These antennas are widely used in mobile applications and handheld
walkie-talkies. They are usually connected
to the vehicle and the design is flexible, so they don't have time
to rest.

The formula for a capacitor is a percentage function of a wavelength.

Matching the choice of inductor, the antenna resonates at the desired
frequency.

When the antenna is fully tuned, then it looks like a pure resistor
tied to the ground. This resistance is
called the radiation resistance.
