WIPO Patent Application WO/2012/101979
Kind Code:
A1
Abstract:
Provided is an electric field probe with which the range of reception can be limited to a desired range when a nearby electric field is measured. The electric field probe (1) comprises: a rod-shaped monopole antenna (20); and a reflection member (30) which is electrically conductive and is disposed coaxially with the monopole antenna (20) so as to cover the monopole antenna (20). The reflection member (30) is formed in a hollow conical shape, and the base face thereof is open in the axial direction of the monopole antenna (20). The monopole antenna (20) is disposed such that the position of a tip (20a) thereof substantially coincides with the open end face (30a) of the reflection member (30).
