Dipole Antenna Calculator

This page provides a Dipole Antenna calculator for determining radiation resistance.

EXAMPLE:

INPUTS:

• Physical Length (meter): INPUT1 = 0.25
• Antenna frequency: INPUT2 = 600 MHz

OUTPUTS:

• Radiation Resistance of halfwave dipole: OUTPUT1 = 80 Ohm
• Radiation Resistance of electrically short dipole: OUTPUT2 = 49.35 Ohm
• Radiation Resistance of hertizian dipole: OUTPUT3 = 197.4 Ohm

Radiation Resistance Equations

The following formulas/equations are used to calculate the radiation resistance of different types of dipole antennas: halfwave dipole, electrically short dipole, and hertzian dipole.
