The equivalent circuit of the antenna ( including loading coil ) is the series combination of the capacitive reactance of the antenna, the inductive reactance of the loading coil, and the radiation resistance and the other resistances of the antenna-ground circuit.

However this understanding does not apply to resonant antennas where the resistance involved is the radiation resistance, a desired quantity which removes energy from the resonant element in order to radiate it ( the purpose of an antenna, after all ! ).
43.
For ever shorter antennas ( requiring greater " electrical lengthening " ) the radiation resistance plummets ( approximately according to the square of the antenna length ), so that the mismatch due to a net reactance away from the electrical resonance worsens.

Because it radiates only into the space above the ground plane, or half the space of a dipole antenna, a monopole antenna will have a dBi and a radiation resistance of about 36.8 ohms if it is mounted above a good ground plane.

The largest resistance in the antenna-ground circuit is often the ground system, and the transmitter power is divided proportionally between it and the radiation resistance, so the resistance of the ground system has to be kept very low to minimize the " wasted " transmitter power.

Dr . J . R . Battista, a Deinococcus expert at Louisiana State University in Baton Rouge, who was not involved in the genome decoding, said, " The part that is absolutely amazing to me is that there is no obvious explanation for its ionizing radiation resistance ."

The radiation resistance of antennas ( the resistance that represents power radiated as radio waves ) drops as their length becomes small compared to a wavelength, so the radiation resistance of antennas on the LF and VLF bands is very low, often as low as one ohm or less.

The mainstream continuity Spiderman exhibits radiation resistance during his fight with Morlun; I m less sure of the fantastic four; in the future I would ask others on the fantastic four talk page whether their gaining their powers would count as this; or if there are later storylines where they survive large amounts of radiation.

In the 1950s and 60s M . S . Neiman proposed the new principle for broadband antennas free from the reflection phenomena and called " antennas of smooth radiation ", and also the new method of calculating the power and radiation resistance of metallic antennas based on the calculation of emission of electrons moving in metal.
