Arched support used for material electromagnetic characteristic measurement in wireless communication channel modeling

Abstract

The present invention relates to the electromagnetic reflection and transmission characteristic measurement technology field, and provides an arched support used for the material electromagnetic characteristic measurement in the wireless communication channel modeling. The arched support comprises a pedestal, a support body, a semi-circular sliding rail, a sliding block and a rotating driving mechanism. The support body is arranged on the pedestal, the semi-circular sliding rail is arranged on the support body, can rotate around the diameter and is equipped with the scales, the rotating driving mechanism is used to drive the semi-circular sliding rail to rotate around a shaft, and the sliding block is arranged on the semi-circular sliding rail and is equipped with a locking mechanism. The beneficial effects of the present invention are that the problems in the building material electromagnetic characteristic measurement in the wireless communication channel modeling that the distances can not be positioned flexibly and accurately and the angles can not be adjusted, are solved; the arched support is suitable for placing different types of antennas; the sliding rail can be moved, is convenient to disassemble and reassemble and can be used for researching the characteristics of the different building materials flexibly; the glass fiber reinforced plastics are used to manufacture the pedestal and the support body, so that the arched support has the characteristics of ultralow microwave scattering, high intensity and corrosion resistance, being insulating, etc.

Description

technical field [0001] The invention relates to the technical field of measurement of electromagnetic reflection and transmission characteristics of actual building materials, in particular to an arch bracket used for measurement of electromagnetic characteristics of materials in wireless communication channel modeling. Background technique [0002] The indoor wireless communication environment is characterized by lower transmission power, shorter coverage distance, and greater environmental changes. For different buildings, the reflection, diffraction, diffraction, refraction (transmission), and scattering of electromagnetic waves are closely related to factors such as the layout of indoor items, material structure, and building scale. In wireless channel modeling, for statistical models, it is often necessary to understand the penetration loss of electromagnetic waves passing through building materials in different scenarios in typical environments; for deterministic model...
