An Epoxy?Based Ceramic?Polymer Composite with Excellent Millimeter?Wave Broadband Absorption Properties by Facile Approach

The development of polymer?based absorbers in millimeter?wave frequency range has triggered a surge of interest due to the ever?growing demands of 5G communication applications. In this work, a systematic investigation on a novel bi?phase composite, i.e., BaNb0.6Fe11.4O19 (BNFO)/epoxy, has been presented. BNFO is the only filler phase that could generate dielectric loss and magnetic loss simultaneously, and epoxy is used as matrix phase for its advantages as a widely used electronic packaging material. The millimeter?wave broadband absorption properties of the composite and related mechanisms were investigated both experimentally and theoretically. When the BNFO content is higher than 60 wt%, a millimeter?wave broadband absorption performance has been observed with a decreased matching thickness and a wider effective bandwidth covering the entire R band. The maximum reflection loss of the composite could achieve ?28.74?dB at 31.43?GHz and ?44.36?dB at 27.18?GHz with a matching thickness of only 0.98 and 0.97?mm when the BNFO content is 60 and 75?wt%, respectively. The comprehensive advantages of the composite, including millimeter?wave broadband absorption properties, facile manufacturing processes, small matching thickness and good compatibility with current electronic packaging materials, would facilitate it to be utilized in next?generation electronic devices.This article is protected by copyright.
