摘要： A method and apparatus for measuring an electromagnetic field are disclosed. In accordance with the apparatus an array of substantially identical antenna elements having a substantially shorter length than a wavelength of the electromagnetic field and being equi-spaced are provided. The spacing is larger than approximately three times the length of the antenna elements. Each antenna element is for sensing the electromagnetic field at a predetermined location and for providing a signal in dependence upon the sensed field. By providing antenna elements meeting the criteria set out herein accurate electromagnetic field strengths are measurable absent significant mutual coupling and scattering effects between the antenna elements.
