In the microwave and millimeter‐wave transmission regions, substrate‐integrated waveguide (SIW) is a very promising candidate for the development of circuits and components. The channel of the SIW is a bandpass or high pass filter. This characteristic impedes the conventional baseband transmission using nonreturn‐to‐zero pulse shaping scheme. As an alternative to using mixers to facilitate a passband transmission, this paper proposes a spectrum shaping scheme of low complexity for the channel of SIW, namely spread reshaping code. It aims at matching the spectrum of the transmit signal to the channel frequency response. It facilitates the transmission through the SIW channel while it avoids using carrier modulation and equalization. Simulations reveal a good performance of this scheme, such that, as a result, eye opening is achieved without any equalization or modulation for the respective transmission channels.
