This invention provides a self-decoupling intermediate frequency (IF) radiating element and a mobile communication antenna, relating to the technical field of wireless communication. The self-decoupling IF radiating element includes a radiating substrate, a dielectric block, two sets of orthogonally polarized dipoles, and four metal patches. The mobile communication antenna includes the self-decoupling IF radiating element. Each metal patch of the self-decoupling IF radiating element forms a capacitive-inductive resonant circuit with each radiating arm. This resonant circuit can add at least one high-frequency resonant point, ensuring that the electrical performance of the self-decoupling IF radiating element remains unaffected while possessing the characteristic of transmitting high-frequency electromagnetic waves. This allows electromagnetic waves generated by the high-frequency radiating element nested below the self-decoupling IF radiating element to effectively pass through, thereby generating good radiation into space. Specifically applied in mobile communication antennas, this eliminates the need for additional decoupling circuits, does not increase insertion loss, and reduces the design complexity and size of common-aperture antennas.
