In electrical engineering and telecommunications the Chu–Harrington limit or Chu limit sets a lower limit on the Q factor for a small radio antenna. The theorem was developed in several papers between 1948 and 1960 by Lan Jen Chu, Harold Wheeler, and later by Roger F. Harrington. The definition of a small antenna is one that can fit inside a sphere whose diameter is 1 π λ – a little smaller than 1⁄3 wavelength in its widest dimension. For a small antenna the Q is proportional to the reciprocal o
