Extended SIW for and Modes and Slotline Excitation of the Mode

摘要

A substrate integrated guide which allows the propagation of both ${rm TE}_{m0}$ and ${rm TE}_{0n}$ modes is presented, the Extended Substrate Integrated Waveguide (ESIW). Its structure combines the working principles of SIWs and SINRD guides. While the performances of the ESIW with ${rm TE}_{m0}$ modes are the same as conventional SIWs, they are better than SINRD guides concerning ${rm TE}_{0n}$-like modes.
