Claim Text:
1. A radio frequency characteristics measurement jig device used to measure a radio frequency device including a signal terminal, comprising: a ground conductor part; a first coplanar line including a first dielectric layer provided on a surface of the ground conductor part, a first center conductive layer provided on a surface of the first dielectric layer, and first ground conductive layers respectively provided outside first gaps provided on both sides of the first center conductive layer on the surface of the first dielectric layer; a connection substrate including a second dielectric layer having a first surface and a second surface on an opposite side of the first surface, a second center conductive layer provided on the first surface, second ground conductive layers respectively provided outside second gaps provided on both sides of the second center conductive layer, and a third ground conductive layer provided on the second surface and connected to the second ground conductive layer, the second dielectric layer including a first region provided with the second center conductive layer and the second ground conductive layer and constituting a second coplanar line, and a second region not provided with the second ground conductive layer outside the second center conductive layer; and a holding part configured to press the connection substrate to the first coplanar line and the signal terminal so as to allow electrical continuity between the first center conductive layer and the second center conductive layer on the first region, to allow electrical continuity between the first ground conductive layer and the second ground conductive layer, and to allow electrical continuity between the second center conductive layer on the second region and the signal terminal.
