Problems solved by technology

In recent years, in the field of electromagnetic compatibility, the requirements for anti-electromagnetic interference performance of products have become higher and higher. Since the electromagnetic interference radiation frequency band of various electronic products is becoming wider and wider, and the low frequency band is particularly dense, and the current used in this field Most of the magnetic field antennas are narrow-band magnetic field antennas, and the test frequency band cannot be adjusted, so a broadband high-gain loop test antenna that can adjust the test frequency band is required

The invention is suitable for shielding efficiency test of a shielding chamber, a shielding square cabin and a cabinet and radiation interference leakage detection test of large-scale electronic equipment and systems.

Description

technical field [0001] The invention belongs to the technical field of electronic testing and measurement, in particular to a wide-band high-gain magnetic field loop test antenna and a design method based on the resonance principle. Background technique [0002] In order to meet the needs of the development of modern electronic technology, the research and development of antennas are mainly developed in the direction of small size, wide frequency band, high gain and adjustable. In recent years, in the field of electromagnetic compatibility, the requirements for the anti-electromagnetic interference performance of products have become higher and higher. Since the electromagnetic interference radiation frequency band of various electronic products is becoming wider and wider, and the low frequency band is particularly dense, and the current used in this field Most of the magnetic field antennas are narrow-band magnetic field antennas, and the test frequency band cannot be adju...
