Abstract
A circuit shielding structure, relating to a technical field of electronics, includes a substrate, wherein: at least one radio frequency component circuit is fixed on the substrate; a wave-absorbing material layer is embedded in the substrate; a shielding wall made of wave-absorbing material is arranged on the substrate and around the radio frequency component circuit; a conductive material layer covers the shielding wall; a closed space is formed among the substrate in which the wave-absorbing material layer is embedded, the shielding wall and the conductive material layer, and the radio frequency component circuit is sealed in the closed space, so that omnidirectional shielding is achieved.
