whip antennas are the most common examples of antennas, single driven elements, and ground plane antennas.

whip antennas are mounted on hard and flexible wires, usually vertically with one end close to the ground plane. a whip antenna may also be called a half-dipole antenna.

these antennas are widely used in mobile applications and handheld radio devices. they are usually fixed to the vehicle and are designed to be flexible so they do not overtime.

the formula for capacitance is a percentage function of wavelength.

matched to the choice of inductor, the antenna resonates at the desired frequency.

when the antenna is fully adjusted, it looks like a pure resistor connected to ground. this resistance is called radiation resistance.
