AbstractWith the rapid development of electronic information technology, antenna systems in the fields of aviation, aerospace, transportation, and 5G communication services are becoming more and more intensive and accurate. Polymer matrix wave-transparent composites with lightweight, low dielectric constant (ε) and dielectric loss tangent (tanδ), high temperature resistance, and excellent mechanical properties are urgently needed in order to ensure high-fidelity transmission of electromagnetic wave and protect antenna systems from external interference. This review introduces the wave transmission mechanism, key compositions (polymer matrix & reinforced fibers), and several typical testing methods for dielectric properties of polymer matrix wave-transparent composites, mainly elaborates the latest research progress and achievements of polymer matrix wave-transparent composites from polymer matrix, reinforced fibers and their surface functionalization methods, and presents the key scientific and technical problems that need to be solved urgently in the application of polymer matrix wave-transparent composites in the antenna systems. Finally, the future development trends and application prospects of the polymer matrix wave-transparent composites are also proposed.
