ANTONICS Online Calculator

With the online calculator from ANTONICS the following antenna performance can be calculated precisely:



Simple calculator that gives the reflected power (in %) at an antenna feeding point when either the return loss (in dB) or the VSWR is given.

Example: 10 % of the power is reflected when the return loss has a value of -10 dB.

Example: More than 18% of the power is reflected when the VSWR has a value of 2,5.

Efficiency dB %

Simple calculator that calculates the efficiency of an antenna.

Example: A value of -3 dB is an efficiency of 50,1 %.

Example: A value of 50,1 % is an efficiency of -3 dB.
