“…The last coupling to be adjusted in order to implement the matrix shown in (2) is given by the element M 14 = −M 34 . This value represents the coupling between the first/last (1,3) bars and the cavity resonance. The coupling will be dependent on the distance from these bars to the top and bottom sidewalls (parameter y r1 = y r3 in Fig.…”

“…IDEBAND devices are required in modern communication systems, including wireless communications, 5G, satellites, or in artificial intelligence platforms. In these applications, where the footprint and volume are critical, planar technologies, such as microstrip [1], substrate integrated waveguide (SIW) [2], [3] or coplanar [4], [5] are usually employed. Using these technologies, the level of losses is normally sacrificed in order to produce structures with reduced dimensions.…”

A new class of wideband bandpass filters based on using thick metallic bars as microwave resonators, instead of common microstrip lines, is presented. These bars provide a series of advantages over fully planar printed technologies, including higher coupling levels between resonators, better unloaded quality factors Q U , and larger bandwidths, implemented with more compact structures. Moreover, thick bar resonators can easily be coupled to an additional resonance excited in a box used for shielding, allowing to realize transversal topologies able to implement transmission zeros at desired frequencies. To illustrate the capabilities of this technology, two microwave filters with different bandwidths and one transmission zero have been designed. One of the filters has been manufactured and tested using copper bars inside an aluminum housing partially filled with Teflon. Measured data demonstrates a fractional bandwidth about FBW = 32%, spurious free range SFR > 50%, unloaded quality factor of Q U = 1180 and return losses over 20 dB without requiring any post-tuning on the prototype, confirming the exciting performance of the proposed technology.Index Terms-Hybrid waveguide microstrip technology, microwave filters, resonator filters, transmission zeros, transversal filters, wideband filters.

“…The Development power dividers (PDs), directional couplers, bandpass filters and diplexers etc, employing SIW technology have gained a great attraction due to their larger Q-factor, lower insertion-loss, low cost, compact size and easily integrable with other components [1][2][3][4][5][6][7]. The SIW power divider becomes a key component at millimeter wave band and widely used in array antennas, multiplexers and power amplifiers (PAs).…”

In this paper, a novel design of highly compact power divider employing substrate-integrated waveguide (SIW) is proposed for dual-band applications. The double-ring asymmetric complimentary split-ring resonators (CSRRs) are utilized to obtain dual-band operation. The asymmetric double-ring CSRRs create mixed magnetic and electric coupling resulting two distinct resonating frequencies which exhibits bandpass behaviour below the resonating frequency of the cavity. The resonating passbands can be designed individually by varying the dimensions of the proposed CSRRs. In addition, the position of output ports can be varied to achieve arbitrary power division. To demonstrate the proposed analysis, three prototypes (two equal power division and one unequal power division) of dual-band SIW power dividers are designed and fabricated. Measurement performance provides a good consistency with that of simulated one. The circuit areas of the fabricated prototypes 1, 2 and 3 excluding microstrip transitions are 0.053λ g 2 , 0.088λ g 2 and 0.033λ g 2 , respectively. The proposed design process exhibits dual-band performance with smaller circuitarea, suitable isolation and hence appropriate for dual-band communication services.

“…The objective is to provide a general background in lowpass filters (a most detailed explanation can be found in [Cameron et al, 2007]). Also, the design technique for lowpass filter is presented in [Vera-Castejón et al, 2014], while in [Máximo-Gutiérrez et al, 2019] is proposed the procedure for their implementation in SIW technology.…”

Porúltimo, para las aplicaciones espaciales en las que los efectos adversos de alta potencia como multipactor y corona son muy importantes, algunos filtros de paso bajo pueden ser requeridos junto con algunos filtros sintonizables, cuyos rangos libres de espurios no son lo suficientemente amplios como para ser empleados en sistemas de comunicación satelital por sí mismos. El uso de material dieléctrico enáreas donde es más probable que se produzca multipactor, evita el libre movimiento de los electrones enáreas críticas. Este concepto se aplica en los filtros paso bajo, elevando el umbral de multipactor. Del mismo modo, los materiales magnéticos con una constante de baja permeabilidad (que en realidad no se encuentra en la naturaleza) pueden ser empleados teóricamente para diseñar filtros Design and Implementation of disruptive techniques of Ku/Ka band tunable filters xiii de paso bajo, siguiendo los mismos principios de trabajo que los materiales dieléctricos. Sin embargo, debido al uso de estos materiales junto al poste metálico, hace resonar los inversores que componen los filtros de paso bajo. Esto, a su vez, provoca que aparezcan algunos ceros de transmisión debido a la interacción con estos inversores resonantes. En consecuencia, estos ceros de transmisión mejoran tanto la selectividad del filtro como el rango libre de espurios.
