“…Compared with the results in [14] (from 4.3 to 7 GHz), according to the same return loss of input port (more than 15 dB) and the same order of return losses of output ports (more than 8 dB), a power divider with wider bandwidth is obtained. The measured results show that the insertion losses are less than 4 dB, the return losses at input port and output ports are better than 11.3 dB and 5.5 dB respectively, and the phase difference between the two output ports is in the range from 177.3 • to 179 • , which illustrates the feature of frequency independence in the range from to 2.8 to 7.4 GHz.…”

“…The input and output ports of these power dividers are coplanar. However, it is not suited to use in some fields, such as the six-port junction [13][14][15] including non-coplanar couplers [16][17][18]. In addition, the six-port technique is a suitable option as the ratio of complex amplitude measurements [19], and has been applied in many fields [20][21][22][23].…”

“…Two output ports are located at different metal layers. An out-ofphase power divider was designed based on the theory of microstripto-slotline transition in [14]. According to [24], an UWB multilayer slotline power divider with bandpass response was presented.…”

“…This circuit consists of a microstrip-to-slotline transition, a T-junction formed by a slotline and two arms of two microstrip lines. The differences between the power divider in [14] and the one in this paper are a tapered slot and a fan-shaped slot taking place of a circular slot to improve the impedance matching between them. Furthermore, this device does not use any resistive element.…”

In this article, four wideband power dividers (two are filtering power dividers) using single-and double-layer periodic spoof surface plasmon polaritons (SSPPs) are proposed. Double-sided parallel-strip line is used to realize the wideband and low loss for the double-layer SSPPs. T-shaped SSPPs power dividers with large bandwidth, wideband isolation, and low loss using double-layer SSPPs to singlelayer SSPPs transition are realized. Conventional coplanar waveguide is used as the output ports for the single-layer SSPPs. Moreover, two new SSPPs power dividers with filtering performance are realized with adding via holes in the double-layer SSPPs. The theoretical analysis, parametric study, and design procedure for these wideband power dividers are illustrated. In addition, for validity demonstration, four wideband SSPPs power dividers are fabricated in microstrip technology and characterized. Good agreements can be observed between the measured and simulated results, indicating good potential applications in the integrated plasmonic devices.

The design of a novel wideband six‐port network on a single layer microstrip substrate is presented.Two different configurations of the single‐layer six‐port networks, one conventional and the other nonconventional, are designed, fabricated, and measured. The six‐port network based on the conventional configuration is formed by one Wilkinson divider and three couplers, with one unused port terminated with a coaxial match termination. The nonconventional six‐port network, proposed here, is constructed using a similar configuration except one of the couplers is replaced by a quadrature power divider eliminating the need for match termination. To obtain fully planar device with wideband operation, the six‐port networks use double‐stage Wilkinson dividers, disk type couplers, and a wireless via 90° phase shifter. Their performances are assessed via full‐wave electromagnetic simulations and measurements. Both the simulated and the measured results show a wide bandwidth of the two six‐port configurations in terms of amplitude and phase characteristics across the frequency band of 4.5–8.5 GHz. © 2012 Wiley Periodicals, Inc.
