“…Compared with the three-way power divider in [5], the presented ones are with better amplitude and phase balance performance. Even though the power divider in [6] is with lower insertion loss and similar amplitude imbalance, its FBW is much narrower, and its thick film fabrication is expensive and complex. Based on all the comparison mentioned above, the proposed SIW power dividers/combiners achieve a good trade-off between bandwidth, isolation, insertion loss, phase, and amplitude imbalances.…”

“…Substrate-integrated waveguide (SIW) integrates the characteristics of the uniplanar rectangular waveguide (RWG) and planar transmission lines, which establish an attractive trade-off between them [1]. During the past few years, a lot of microwave components and circuits have been realized in SIW technology, among which SIW power dividers with high isolation and broad bandwidth have attracted unique attention since they are highly desired in power-combining amplifiers and phased array antennas [2–6]. In [2], a half-mode SIW (HMSIW) power divider with transverse electric – 20 (TE 20 ) mode suppression achieved isolation over 10 dB with an operation frequency range of 18–35 GHz.…”

“…Unfortunately, its phase imbalance can exceed 10° in several frequency ranges, and insertion loss at edges of its pass-band rolls off rapidly. Recently, a multilayer SIW power divider with embedded thick film resistive septum exhibits over 22 dB isolation over 18.5–22 GHz [6]. Another SIW power divider integrated with thick film resistive layer even shows 40% FBW with 20 dB isolation [7].…”

In this paper, a 3 dB H-plane substrate-integrated waveguide (SIW) power divider/combiner with improved isolation is reported. By adding two isolated ports into the Y-junction, it will perform like a multi-port coupler, so that the isolation between its dividing ports can be effectively improved as the newly-added ports are properly matched. To verify the availability and effectiveness of this concept, two prototypes, one is terminated by coaxial terminations and the other is loaded with lumped resistors, are developed. Their measured results are separately in good agreement with their corresponding simulations. Meanwhile, isolations better than 16 dB with fractional bandwidth (FBW) of 35 and 25% are achieved, respectively, as well as low phase and amplitude imbalances. Compared with some reported similar SIW power dividers, the proposed ones exhibit wider FBW with similar isolation, insertion loss, phase, and amplitude balance performance.

This article deals with multilayer substrate integrated waveguide (SIW) six-port junctions with embedded carbon resistive films. SIW six-ports usually employ reactive power dividers, which degrade the amplitude and phase balance when the six-port is terminated with mismatched power detectors. The associated impairments are studied and two SIW six-port junctions with improved isolation and output matching are designed for K-/Ka-band applications to overcome these limitations. The proposed designs differ with respect to the configuration of the output ports making the underlying six-port topology applicable for different layout requirements. Measurements of the fabricated components validate the concept. The six-ports are compact, fully shielded and can be integrated in multilayer printed circuit boards.

The ongoing developments of satellite antenna technology, mainly of multiple-feed-per-beam (MFB) concepts, combined with advanced compound semiconductor and packaging technologies that provide the building blocks for a new generation of K-band satellites, are reported. This paper proposes a next-generation MFB application scenario using the advantages of both new antenna and solid-state power amplifier concepts
