Whip antenna calculator

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.

Usage example

Input data:

Frequency: 200 MHz

Length: 80 inches

Diameter: 10 inches

Click "Calculate" to output data

Capacitance: -2.032pF Induction coefficient: -311.666nH One quarter of the wavelength: 0.375m Antenna length: 541.8867% Radiant resistance: 0 ohms
