报告摘要（Abstract）:

An isosceles right triangular waveguide with one electric wall and two magnetic walls is proposed to design microwave applications implemented in substrate integrated waveguide. The complete closed-form modal solutions are presented for both transverse electric and transverse magnetic modes in the isosceles right triangular waveguide. The resonant frequencies of a resonator made of a short isosceles right triangular waveguide can then be calculated. A structure named as quarter-mode substrate integrated waveguide (QMSIW) is introduced to realize the proposed triangular waveguide resonator in a compact and planar form. Simulated electric field distributions of modes excited in the QMSIW are in good agreement with theoretical predictions for the solid waveguide structure, demonstrating the feasibility of QMSIW resonators. Finally, two circularly-polarized antennas and one compact triple-mode filter are designed and fabricated based on the discussed QMSIW. The performances of the designed applications are tested, and measured results agree very well with simulated ones, which demonstrates that the proposed QMSIW structure is an excellent candidate for compact microwave applications.
