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.
