Disclosed in the present invention is a same-band combiner, comprising a bottom housing and a cover. A 3dB bridge is provided in the bottom housing, and comprises a main coupling line strip and a secondary coupling line strip; the main coupling line strip comprises a first rectangular main strip; both ends of the first rectangular main strip are respectively extended to two sides to form L-shaped first curved strips; the free end of each first curved strip is extended to form an L-shaped second curved strip; the second curved strip on one side is extended to form a first input end, and the second curved strip on the other side is extended to form a first output end. By means of the invention, better coupling effects can be achieved within a frequency range between 0.8 Ghz and 2.8 Ghz; the phase difference between a path S21 and a path S31 is not more than ±5°, and meets the requirement for a phase difference of 90° for a 3dB bridge.
