“…The main isolation networks include one or more resistors and the microstrip-based network [25,26]. Secondly, the filtering power dividers (FPD) are proposed to combine the power divider and filter to realize the miniaturization of the circuit [27][28][29]. Thirdly, ultra-wideband and wideband isolation PDs are fabricated [30,31].…”

With the development of microwave wireless communication technology, microwave passive frequency selectivity circuits are developing toward multi-function and miniaturization. Substrate-integrated waveguide (SIW) devices have good development prospects in miniaturization and integration. The research on devices based on SIW is lack unified theoretical combing. This chapter describes the novel circuits based on substrate-integrated waveguide, including filter, power divider, switch, phase shifter, diplexer, and crossover. This chapter describes the design methods and special properties of these circuits. The display of these circuits is expected to give some inspiration to your research.

“…In recent years, new power dividers with multi-section combined/metamaterial structures, multi-band and multifunction have been developed with the requirement of integration and miniaturization for microwave circuits. In, 25 a multiple-section Gysel and Wilkinson combined power divider with arbitrary power division ratios is proposed, and in, 26,27 multi-band power dividers based on substrate integrated waveguide and metamaterial structure have been developed, respectively, while in, 28 a resistor-less millimeter-wave power divider with metamaterial structures is designed. Filtering balun power dividers using the modified Schiffman phase shifter, 29 filtering power divider based on graphene nanoplates, 30 and balanced-to-unbalanced NGD power divider 31 also have been developed in the recent years.…”

“…Filtering balun power dividers using the modified Schiffman phase shifter, 29 filtering power divider based on graphene nanoplates, 30 and balanced-to-unbalanced NGD power divider 31 also have been developed in the recent years. It is noted that nearly all of these new power dividers [25][26][27][28][29][30] have positive group delay, and almost all of the reported power dividers are microstrip planar structures.…”

In this article, a matched branch line-loaded negative group delay (NGD) circuit without resistor is presented firstly, and then an Wilkinson power divider with NGD characteristic is implemented by integrating the NGD circuit and the power divider by using self-packaged suspended coplanar waveguide (SCPW) technology. The self-packaged SCPW power divider with NGD characteristic has been fabricated, and the design has been demonstrated by measurement, which indicates that the proposed power divider with NGD characteristic has a measured signal attenuation (S 21 ) of 10.92 dB, a S 11 attenuation of 32.1 dB, an NGD time of À2.42 ns, and an isolation of no less than 39 dB at the center frequency, while simple circuit topology, self-packaging and compact circuit size have also been achieved.

“…Furthermore, in [6], a novel dual-band reconfigurable antenna is reported, which is capable of dual-band operation by loading an electrically small CSRR structure. In 2021, compact triple-band and quad-band SIW power dividers based on unequal CSRRs and U-shaped slots are developed [7]. Experiment results show that the proposed power divider prototypes exhibit attractive performance in terms of multiband operation, compact size, good return loss, and high isolation.…”
