Detection device for evaluating internal electronic elements of a test object

A detection device, configured to detect an output electromagnetic wave signal passing through a test object, and comprising:

• an electromagnetic wave signal generating unit, configured to generate an initial electromagnetic wave signal;
• an output element, configured to output the initial electromagnetic wave signal, wherein the output element comprises at least one transmitting antenna;
• a receiving element, configured to receive the output electromagnetic wave signal, wherein the receiving element comprises at least one receiving antenna;
• and
• a measuring unit, configured to measure a value of the output electromagnetic wave signal, wherein the measuring unit comprises a radio frequency power meter, the test object is disposed between the output element and the receiving element, and the initial electromagnetic wave signal transmitted from the output element to the test object is converted into the output electromagnetic wave signal by an electronic element in the test object when passing through the test object.
