Noise Temperature of Antenna Solution

STEP 0: Pre-Calculation Summary

Formula Used

Antenna Temperature = (Power Density of Antenna)/(Thermal Resistance*Bandwidth)
T_a = (S)/(k*B_a)
This formula uses 4 Variables

Variables Used

Antenna Temperature - (Measured in Kelvin) - Antenna Temperature is a measure of the noise being produced by an antenna in a given environment.
Power Density of Antenna - (Measured in Watt Per Cubic Meter) - Power Density Of antenna is the measure of the power from an antenna to a certain distance D.
Thermal Resistance - (Measured in Kelvin per Watt) - Thermal resistance is a property of the resistor that quantifies how effectively it dissipates heat. It is measured in Kelvin per watt (k/w).
Bandwidth - (Measured in Hertz) - The Bandwidth is a range of frequencies, or information, that a circuit can handle or the range of frequencies that a signal from antenna occupies.

STEP 1: Convert Input(s) to Base Unit

Power Density of Antenna: 55 Watt Per Cubic Meter --> 55 Watt Per Cubic Meter No Conversion Required
Thermal Resistance: 12.25 Kelvin per Watt --> 12.25 Kelvin per Watt No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

T_a = (S)/(k*B_a) --> (55)/(12.25*0.26)

Evaluating ... ...

T_a = 17.2684458398744

STEP 3: Convert Result to Output's Unit

17.2684458398744 Kelvin --> No Conversion Required

FINAL ANSWER

17.2684458398744 ≈ 17.26845 Kelvin <-- Antenna Temperature

How is antenna noise temperature determined?

A parameter often encountered in specification sheets for antennas that operate in certain environments is the ratio of gain of the antenna divided by the antenna temperature (or system temperature if a receiver is specified). This parameter is written as G/T, and has units of dB/Kelvin [dB/K].

How to Calculate Noise Temperature of Antenna?

Noise Temperature of Antenna calculator uses Antenna Temperature = (Power Density of Antenna)/(Thermal Resistance*Bandwidth) to calculate the Antenna Temperature, The Noise Temperature of Antenna formula is defined a measure of all noise that enters a receiver through its antenna. These contribute to the receiver system noise temperature. Antenna Temperature is denoted by T_a symbol.

How to calculate Noise Temperature of Antenna using this online calculator? To use this online calculator for Noise Temperature of Antenna, enter Power Density of Antenna (S), Thermal Resistance (k) & Bandwidth (B_a) and hit the calculate button. Here is how the Noise Temperature of Antenna calculation can be explained with given input values -> 17.26845 = (55)/(12.25*0.26).

FAQ

What is Noise Temperature of Antenna?

The Noise Temperature of Antenna formula is defined a measure of all noise that enters a receiver through its antenna.
