Abstract: A miniaturized diplexer with wide-stopband based on half-mode substrate integrated waveguide (HM‐SIW) is proposed. The diplexer combines dual-mode resonator (DMR) with single-mode resonators (SMRs). The employment of HMSIW technology breaks through the limitations of SMRs on miniaturization, while effectively addressing the limitation on wide-stopband performance that is typically encountered with the TE202 mode in the SMRs. A second-order prototype, centered at 10.34 GHz and 13.9 GHz, has been designed and fabricated, utilizing a TE101/TE301 DMR. The measured out-of-band rejection is better than 20 dB with a frequency of up to 2.16 f ₁. Meanwhile, the size of the diplexer is reduced to 1.363 λ _g².

摘要：基于半模基片集成波导（HMSIW），提出一种宽阻带小型化双工器。该双工器将双模谐振器（DMR）与单模谐振器（SMR）相结合。采用HMSIW技术突破了SMR在小型化方面的限制，同时有效解决了SMR中常见的TE₂₀₂模式对宽阻带性能的限制。采用TE₁₀₁/TE₃₀₁DMR设计并制造了一个二阶原型，原型的中心频率分别为10.34 GHz和13.90GHz。测量结果显示，该双工器的阻带范围为2.16f₁（f₁是通道1的中心频率），具有优于20 dB的带外抑制水平。与此同时，该双工器的尺寸被显著缩小至1.363λ_g²（λ_g是f₁时介质基底中的导波波长）。
