Abstract: Using the test data of a foreign company’s microwave composite dielectric board as a reference, the standing wave and insertion loss of a domestic microwave composite dielectric board with dielectric constant of 2.94 at 10 GHz are measured by means of a 50 Ω impedance-matching circuit. The test results show that the dielectric properties of the domestic microwave composite dielectric board meet the circuit requirements. Through the performance test in high/low temperature environments, the results show that the consistency of domestic plate is slightly lower than those of foreign products, and the stability and consistency of the preparation process still need to be improved and optimized.
