Abstract

AbstractIn 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.

Highlights

Substrate integrated waveguides (SIW) are a very promising candidate for the development of circuits and components in the microwave and millimeter-wave transmission regions.[1,2,3,4,5] In these regions, conventional microstrip or coplanar waveguides perform poorly in reaching a wide band transmission because of high conductor and dielectric losses at high frequencies
Considering the energy consumption constraint as well as the sensitivity to the time jitter, a tradeoff should be made between the performance and the allowable switching frequency
The band pass and high pass channel characteristics of the SIW are analyzed in this paper

Introduction

Substrate integrated waveguides (SIW) are a very promising candidate for the development of circuits and components in the microwave and millimeter-wave transmission regions.[1,2,3,4,5] In these regions, conventional microstrip or coplanar waveguides perform poorly in reaching a wide band transmission because of high conductor and dielectric losses at high frequencies.
