Low-Cost and High-Q Millimeter-Wave Resonator Using Substrate Integrated Waveguide Technique

Abstract

A substrate integrated waveguide (SIW) cavity directly coupled to a planar circuit, i.e. microstrip line or coplanar waveguide, is presented. Different coupling topologies and coupling probes are discussed. Empirical equations to predict the resonance frequencies of the cavity are provided. A temperature stability and tolerance analysis of the cavity is also discussed. A number of prototypes of cavities with different coupling topology were fabricated and measured. Finally, as an example ofpotential applications, a filter using two SIW cavities was designed and measured.

Vertical Transition in Multilayer Millimeter Wave Module Using Circular Cavity

“…The condition for decreasing leakage of via walls effectively, that is 2r/p = 0.5 (6) which mentioned in [11] can be satisfied. Return loss for different θ values of θ < 90 • and θ ≥ 90 • were shown in Fig.…”

“…The distance between centre line of the aperture and circle centre d; the length of the stub l (calculated from centre line of the aperture); /4), h 0 = 2 mm, w 0 = 0.2 mm, R 0 = 1.6 mm, the transition structure was modeled with solid wall firstly and then the solid wall was replaced by vias-array under the guidelines of references [8][9][10][11], Some applications of SICC can be found in references [12][13][14], some important design guidelines can be found in [15][16][17][18][19]. The radius of the cavity R and the gap location d were two key parameters in designing of the transition structure; the R can be calculated with (3), and the parameter d was approximately λ g /4 ; the width of the microstrip lines were calculated to guarantee a 50 Ω impedance.…”
