Abstract: A position-adjustable probing device comprises a stationary probe comprising a first coaxial structure having a first needle core, a first dielectric layer, and a first exterior conductive layer, and a first and a second movable probes. The first movable probe arranged at a first side of the stationary probe comprises a ground needle core, and a first extending structure comprising a first planar structure electrically contacted with the stationary probe through a first movement, a first top surface and a first bottom surface. The second movable probe arranged at a second side of the stationary needle comprises a second coaxial structure comprising a second needle core, a second dielectric layer, and a second exterior conductive layer, and a second extending structure comprising a second planar structure electrically contacted with the stationary probe through a second movement, a second top surface, and a second bottom surface.
