For the fifth generation wireless communication system, millimeter-wave absorber has been frequently used in the measurement of high-power devices, such as transmitting antennas of base stations or satellite communication antennas, etc. The overheat inside the absorber can always be a matter of concern because it may lead to catastrophic fire in the anechoic chamber. A novel pyramidal structure with vent holes and heat sinks was proposed to improve the heat dissipation. The power-handling capability of the wave absorber could be improved by increasing the heat dissipation path without changing the characteristics of the base material. Multiphysics simulation was carried out to analyze the thermal-electromagnetic interaction. This absorber can be used to measure the high-power antenna and the radar system inside anechoic chambers, with power density up to 7 kW/m2. [ABSTRACT FROM PUBLISHER] |
