Formula for Whip Antenna Calculator
A whip antenna is a flexible monopole antenna whose tip or body can physically move like a whip. Hence the name whip antenna. It consists of a long straight flexible wire or rod, which is connected to a radio receiver or transmitter. The whip antenna is designed to be flexible and therefore, it does not break easily upon bending. Longer whip antennas, which are usually used for mounting on vehicle tops, are made of flexible fiberglass material with a wire core and can measure up to 11 meters in length.
Whip antennas exhibit omnidirectional radiation pattern i.e. it radiates electromagnetic waves equally in all the directions. They are ideal for high frequency HF, VHF, and UHF radio bands, handheld radios, cordless phones, walkie-talkies, FM radios, Wi-Fi-enabled devices, and 2-way radios for wheeled vehicles and aircrafts.
Design Parameters of a Whip Antenna:
fre = frequency
Dia = Diameter
Len = Length
C = Capacitance of the antenna
L = Inductance of the antenna
Len% = Length of the antenna in percentage
λ = Quarter Wavelength
R = Radiation Resistance
By entering the frequency, length, and diameter of the whip antenna, this tool can easily calculate the capacitance, inductance, quarter wavelength, antenna length, and radiation resistance.
