Title:
TRANSMISSION WAVE-ABSORBING STRUCTURE AND ANTENNA IN-BAND CHARACTERISTIC TEST SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/206922
Kind Code:
A1
Abstract:
The present invention relates to the technical field of microwave antenna engineering design of radar and communication systems. Disclosed are a transmission wave-absorbing structure and an antenna in-band characteristic test system. In the transmission wave-absorbing structure provided in the present invention, equivalent electric walls are used in combination with equivalent magnetic walls, such that electric walls and magnetic walls for the placement of four objects of the equivalent electric walls and the equivalent magnetic walls form a standard TEM waveguide, and the irradiation of plane waves to an antenna under test can be simulated in a closed environment. Moreover, the test system provided in the present invention is constructed on the basis of a closed induction field area, such that, compared with a traditional near-field method or far-field method, the present invention has the advantages of low electromagnetic leakage, not requiring wave-absorbing materials in a test environment, and not requiring tests in a microwave near-field or far-field anechoic chamber.
