Spherical scanning type antenna measurement system and signal transmission mechanism thereof

A signal transmission mechanism, comprising:

• a first cable carrying arm comprising a first main body and a first connecting portion wherein the first main body comprises a first end and a second end, and the first connecting portion is disposed at the first end;
• a second cable carrying arm comprising a second main body and a second connecting portion wherein the second main body comprises a third end and a fourth end, and the second connecting portion is disposed at the third end;
• a pivoting module connected to the first connecting portion and the second connecting portion so that the first cable carrying arm and the second cable carrying arm can be rotated with respect to each other;
• wherein the first cable carrying arm is configured to carry a first cable and the second cable carrying arm is configured to carry a second cable;
• wherein the first cable and the second cable are electrically connected through the pivoting module;
• wherein a signal is transmitted from the first cable through the pivoting module to the second cable;
• wherein the first cable and the second cable are not deformed when the first cable carrying arm and the second cable carrying arm are rotated with respect to each other.
