Transmission line system with horizontal polarized electromagnetic gield

Abstract

The invention discloses a transmission line system with a horizontally polarized electromagnetic field. A suspended rectangular top frame is connected with a plurality of pillars, and an extension base is fixedly connected to the bottom of each pillar. A side plate group formed by connecting side plates, each lower side plate is in contact with a common grounding plate, wherein a movable radiant plate connected to the aforementioned upper side plate is provided on the aforementioned rectangular top frame, when the radiant plate is placed in the first position When parallel to the ground plane, a vertically polarized electric field can be established; when the radiating plate is placed in the second position relatively perpendicular to the ground plane, a horizontally polarized electric field can be established.

Description

technical field [0001] The present invention relates to an electromagnetic test system used in large devices (such as automobiles, locomotives, etc.), especially a transmission line system (TLS) that can establish vertical and horizontal polarized electric fields through movable plates. Background technique [0002] In order to prevent the electronic devices on the vehicle (such as the instrument panel on the vehicle) from malfunctioning due to electromagnetic interference when driving through an environment with strong electromagnetic waves, the entire vehicle must be subjected to various extreme conditions during research and development. Polarization (vertical polarization and horizontal polarization) electromagnetic wave tolerance test. This kind of electromagnetic wave test for vehicle devices such as locomotives and automobiles is generally carried out in a professional airtight laboratory, and according to the test content, test method and vehicle electromagnetic comp...

Problems solved by technology

[0003] Conventional transmission line systems can only generate vertically polarized electric fields. In the process of testing the electromagnetic wave tolerance of small electronic products, as long as the vertically polarized electric field test is completed, the small electronic products can be turned over. Horizontally polarized electric field test, however, this method cannot be applied to the electromagnetic wave tolerance test of large devices

Due to the large size and weight of the object to be tested, it is not feasible to turn it over to accept the electromagnetic wave test. Therefore, in terms of the accuracy of the vehicle tolerance test, the conventional transmission line system cannot fully consider
