What is the significance of Radiation resistance?

Antennas are classified as large loop when the circumference is almost equal to the wavelength.The is conventionally defined as the value of loss resistance that would dissipate the same amount of power as heat, as is dissipated by the radio waves emitted from the antenna, when fed at a minimum-voltage / maximum-current point ("voltage node").

What kind of antennas are considered large loop?

Large loop antennas are also called as resonant antennas. They have high radiation efficiency. These antennas have length nearly equal to the intended wavelength.

How to Calculate Radiation Resistance of Large Loop?

Radiation Resistance of Large Loop calculator uses Radiation Resistance of Large Loop = 3720*Area of Large Circular Loop/Wavelength in Loop Antenna to calculate the Radiation Resistance of Large Loop, The Radiation resistance of large loop formula is defined as an effective resistance, due to the power carried away from the antenna as radio waves.Unlike conventional resistance or "Ohmic resistance", radiation resistance is not due to the opposition to current (resistivity) of the imperfect conducting materials the antenna is made of. Radiation Resistance of Large Loop is denoted by R_large symbol.

How to calculate Radiation Resistance of Large Loop using this online calculator? To use this online calculator for Radiation Resistance of Large Loop, enter Area of Large Circular Loop (a) & Wavelength in Loop Antenna (λ_a) and hit the calculate button. Here is how the Radiation Resistance of Large Loop calculation can be explained with given input values -> 330.6299 = 3720*8/90.011.

FAQ

What is Radiation Resistance of Large Loop?

The Radiation resistance of large loop formula is defined as an effective resistance, due to the power carried away from the antenna as radio waves.Unlike conventional resistance or "Ohmic resistance", radiation resistance is not due to the opposition to current (resistivity) of the imperfect conducting materials the antenna is made of and is represented as R_large = 3720*a/λ_a or Radiation Resistance of Large Loop = 3720*Area of Large Circular Loop/Wavelength in Loop Antenna.
