Enter the noise power and the noise bandwidth into the Calculator. The calculator will evaluate the Antenna Noise Temperature. 

Antenna Noise Temperature Formula

T = Pn / (1.380649×10^-23*B)


  • T is the Antenna Noise Temperature ()
  • Pn is the noise power
  • B is the noise bandwidth

To calculate Antenna Noise Temperature, divide the noise power by the product of the noise bandwidth and Planck’s constant.

How to Calculate Antenna Noise Temperature?

The following steps outline how to calculate the Antenna Noise Temperature.

  1. First, determine the noise power. 
  2. Next, determine the noise bandwidth. 
  3. Next, gather the formula from above = T = Pn / (1.380649×10^-23*B).
  4. Finally, calculate the Antenna Noise Temperature.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

noise power = 1.5

noise bandwidth = 3
