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. Herein, a systematic investigation on a novel biphase composite, i.e., BaNbFeO (BNFO)/epoxy, is presented. BNFO is the only filler phase that can 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 are investigated both experimentally and theoretically. When the BNFO content is higher than 60 wt%, a millimeter-wave broadband absorption performance is observed with a decreased matching thickness and a wider effective bandwidth covering the entire R band. The maximum reflection loss of the composite can 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 contents are 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, facilitate it to be utilized in next-generation electronic devices.
