Claim:
1. A calibration kit that is applied to a calibration of a probe system, comprising: a substrate; and a through pattern, wherein the through pattern comprises: a first conductive pattern formed at a first surface of the substrate and having a first signal pattern and one or more first ground patterns spaced from the first signal pattern; a second conductive pattern formed at a second surface of the substrate opposite to the first surface and having a second signal pattern having a mirror-image symmetric structure together with the first signal pattern and one or more second ground patterns having a mirror-image symmetric structure together with the first ground patterns; and a through electrode having a first through electrode configured to pass through the substrate and to electrically connect the first signal pattern with the second signal pattern and one or more second through electrodes configured to pass through the substrate and to electrically connect the first ground patterns with the corresponding second ground patterns.
