The present invention provides a capacitively coupled stripline to microstrip transition which comprises a stripline (1), a microstrip (2), an upper conductive ground plane (3), a lower conductive ground plane (4), an insulating layer (5) and an insulating fixing component (6). The stripline is positioned between the upper conductive ground plane and the lower conductive ground plane, and has a stripline overlap section (11). The microstrip is mounted on the upper conductive ground plane, and has a microstrip overlap section (21) which penetrates the upper conductive ground plane. Wherein the microstrip overlap section, the insulating layer and the stripline overlap section are attached uniformly and tightly in sequence and fixed together by the insulating fixing component. The present invention further provides an antenna comprising this transition. Therefore the present invention is designed skillfully, simple in structure, simple and convenient to assemble, has a low cost, avoids metals' direct contact to eliminate the PIM problem, further prevents the parallel plate mode, to further eliminate the PIM risk, improve insertion loss and provide high isolation from neighboring transitions, to completely eliminate unstable factors, and therefore is suitable for large-scale popularization.
