Whip antenna calculator | monopole antenna calculator

This Whip Antenna calculator calculates various parameters of whip antenna or monopole antenna. This calculator on the whip antenna mentions formula or equations used for calculations.

One might have seen long straight rod on the car, it is known as whip antenna. It consists of flexible wire. The bottom part is connected with radio receiver or the radio transmitter. This type of antenna does not break easily while in the motion and hence the name "whip".

The figure-1 depicts whip antenna. Usually whip antenna having quarter wavelength is used. They are basically monopole antennas used in HF/ VHF/ UHF frequency bands.

Typicall applications of whip antennas are as listed below:
• Cell phones
• Walkie-Talkies
• Cordless phones
• FM Radio
• WiFi devices
• GPS devices

Whip antenna has omni-directional radiation pattern as it is monopole antenna. Hence it is also referred as monopole antenna.
