Isotropic Antenna
In order to conduct EMF measurements, an Anritsu isotropic antenna is required. Anritsu offers the 2000-1800-R isotropic antenna for use with the Electromagnetic Field Measurement System. The 2000-1800-R operates over a frequency range of 9 kHz to 300 MHz. This antenna is a tri-axis H-Field sensor with an integrated RF switch device, microcontroller, and memory. Each of the three sensors is situated orthogonally inside the antenna housing to transmit and receive a spherical radiation pattern. In this way, all radiation at the antenna’s geographical position is measured, regardless of direction of arrival.
