TL;DR: In this article, a new class of broadband and fully 3D printed $E$ -plane coax-to-waveguide transition and a monolithically 3-D printed waveguide magic-T based on the transition are presented.

TL;DR: In this article, a GaAs-based wideband spoof surface plasmon polariton (SSPP) waveguide with super compact size is presented at millimeter-wave regime.

TL;DR: In this paper, an 8-order dual-mode waveguide filter was fabricated using the selective laser melting (SLM) technique, employing four dimpled ellipsoid dualmode resonators, operating at the fundamental TM101 mode.

TL;DR: In this paper, a high selectivity wideband bandpass filter (BPF) is proposed based on a stepped impedance open-stub loaded ring resonator, where the resonant modes can be adjusted by the parameters of the stepped impedance stubs and eventually to tune the bandwidth conveniently.

TL;DR: This method can synthesize dual-band bandpass filters with a large range of fractional bandwidth and at the same time, wide center frequency ratio and reduce the sensitivity of S parameters to the values of the circuit elements significantly.
