Antenna Selection by Test Type
IEEE STD 291
IEEE standard methods for measuring electromagnetic field strength of sinusoidal continuous waves, 30 Hz to 30 GHz
Summary: Two standard methods for field-strength measurement are described. The standard-antenna
method consists of measuring the received power or open-circuit voltage developed in a standard
receiving antenna by the field to be measured and computing the field strength from the measured
voltage and the dimensions and form of the standard antenna. The standard-field method consists of
comparing voltages produced in an antenna by the field to be measured and by a standard field,
the magnitude of which is computed from the dimensions of the transmitting antenna, its current
distribution, the distance of separation, and effect of the ground. The measurement procedures are
outlined, including calibration of commercial field strength and extension of the methods to
microwave frequencies. Methods for measuring power radiated from an antenna under several different
conditions are briefly presented, and the important considerations for securing useful and accurate
measurements are described.
