1. A test device for a wireless electronic device, comprising:
- a metal casing;
a RF-absorbing material disposed in the metal casing to enclose an inner space, wherein the RF-absorbing material includes a clamping groove formed at one end of the RF-absorbing material;
a first measurement antenna disposed in the clamping groove and located at one end of the inner space; and
an impedance adjustment module electrically connected to the first measurement antenna for receiving a signal transmitted from the first measurement antenna or transmitting an electrical signal to the first measurement antenna, wherein the impedance adjustment module comprises;
a dielectric layer;
a microstrip line disposed at one side of the dielectric layer and comprising a first body; and
a slot line disposed at the other side of the dielectric layer opposite to the microstrip line, the slot line electrically connected to the first measurement antenna and comprising a second body, wherein the first body and the second body are substantially parallel to each other.
