| 摘要 |
The invention relates to a device for measuring the gain of an electromagnetic field sensor (CP), comprising an electromagnetic wave source and an antenna that is connected to the electromagnetic wave source and radiates an electromagnetic field towards the sensor. The invention is characterised in that the antenna is a monoconical antenna comprising a planar conductive element (P) having a first surface and a second surface opposite the first surface and a conductive part in the form of a cone (C) arranged on the side of the first surface. The invention is applicable to gain measurements on very wide frequency bands. |
