## Abstract The relation of Q and half‐power bandwidth for antennas, Q = 1/BW, is well known. Here it is shown that 1/Q gives an accurate bandwidth for electrically small dipoles and loops. Bandwidths from 1/Q are compared with exact bandwidths, using a sinusoidal current computer model for dipoles
