ABSTRACT:
A first microstrip line100transmits a predetermined input signal. A coupling line includes a gap120along a transmitting direction of the input signal, and the gap120forms a plurality of paths having different path lengths. The input signal is divided by the gap120into divided signals. The paths are electrically coupled to the first microstrip line100at a first region to transmit the divided signals. A second microstrip line105is provided in parallel with the first microstrip line and electrically coupled to the coupling line at a second region. The second microstrip line105transmits each of the divided signals transmitted through the coupling line.
