摘要：

The relation of Q and half-power bandwidth for antennas, Q = I/BW, is well known. Here it is shown that I/Q gives an accurate bandwidth for electrically small dipoles and loops. Bandwidths from I/Q are compared with exact bandwidths, using a sinusoidal current computer modelfor dipoles, and a constant current modelfor loops. (c) 2007 Wiley Periodicals, Inc.
