Title:
RADIO WAVE MEASUREMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/134715
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a radio wave measurement device that can measure radio waves under a plurality of conditions in a short period of time. The present invention is provided with: a housing that includes a metal layer; a horizontally polarized wave antenna that is disposed on one surface of the housing and receives horizontally polarized waves; a vertically polarized wave antenna that is disposed on the same surface as the horizontally polarized wave antenna and receives vertically polarized waves; a switching unit that is connected to the horizontally polarized wave antenna and the vertically polarized wave antenna; and an output unit that is connected to the switching unit. The switching unit is provided with a connection part and a resistor, and switching is performed so that only one of the horizontally polarized wave antenna and the vertically polarized wave antenna is connected to the connection part and the other antenna is connected to the resistor.
