Abstract
The present miniature apparatus for measuring electromagnetic signals comprises a microwave chamber, a first stand positioned in the microwave chamber, a device under test positioned on the first stand, a second stand positioned in the microwave chamber, an optical electromagnetic field sensor positioned on the second stand. The optical electromagnetic field sensor can measure electromagnetic signals generated by the device under test. Since the size of the optical electromagnetic field sensor is only several centimeters, to perform the measurement needs a microwave chamber with a space only about 1 cubic meter, whose construction cost is much lower than that of the prior art. Consequently, the present invention can measure the electromagnetic properties of miniature antennas at a very low cost. Particularly, the present miniature apparatus is portable, while the conventional microwave chamber is too huge to be moved.
