“…It must be noted that the values of Z e1 and Z o1 should be close to each other under the condition Z o1 < Z e1 for the APCL sections to be fabricable. The ABCD parameters are obtained from the transformation relation in Equation (6) and are expressed in Equation (7).…”

“…The pressing needs of emerging wireless applications over the years have directed considerable research to multiband devices. The existing literature is replete with dual‐band impedance transformer architectures [1–21], but most of them have fundamental limitations, namely, a lower frequency ratio (r) and impedance transformation ratio (k) [3–10]. The well‐known Monzon transformer [2] theoretically allows very high values for the frequency and impedance transformation ratios, but the obtained design parameters become highly restricted because of fabrication limits.…”

A design scheme is presented for an all-pass coupled-line (APCL)-based dual-band impedance-matching network. Salient features include a highly flexible frequency ratio (r) (high of 15 and low of 1.2) and impedance transformation ratio (k) (high of 9 and low of 0.2) simultaneously at two arbitrary, uncorrelated frequencies of interest. The design strategy consists of two APCL sections and a stub that prove to be simple and easy to prototype. Detailed mathematical modelling and graphical interpretations have been presented. Closed-form design equations have been developed and backed up with design examples. Two dual-band T-junction power dividers (TPDs) have been designed to demonstrate the application of the proposed impedance transformer at two widely separated frequencies. RO4350 B-and RO5880-based prototypes have been fabricated for both the matching network and the TPD to validate the proposed theory. The measurement results demonstrate an achievable frequency ratio of 15 and an impedance transformation ratio of 9 in simultaneous operation mode.This is an open access article under the terms of the Creative Commons Attribution-NoDerivs License, which permits use and distribution in any medium, provided the original work is properly cited and no modifications or adaptations are made.

This article presents the design, conceptualization, and validation of a generalized architecture for a Wilkinson Power Divider (WPD). The proposed design strategy highlights the versatility of incorporating a broad variety of dual‐band impedance transformers as a part of the WPD, thereby extending its range of applications. As an example, a DC blocking variant of the proposed WPD has also been designed for demonstration. Simple closed‐form design equations have been developed and validated with classical examples and case studies. Finally, two prototypes‐ one ordinary and another DC blocking variant have been fabricated on RO4350 (ɛr = 3.6) substrate and measured. The measurement results are well in accordance with the simulations, thereby validating the proposed design theory.

Computer-aided design modeling of microstrip step discontinuity on multilayer iso/anisotropic substrates with transient signal analysis

A computer-aided design modeling is presented to compute a shunt capacitance and series inductance of π or T-equivalent network parameters of microstrip step-discontinuity at a junction on multilayer iso/anisotropic substrates. The results of the proposed model of shunt capacitance and series inductance have shown permissible agreement with simulation results by the average deviation of 4.5% and 4.9% for 1 < ε r ≤ 40 and w 1 /w 2 < 10 respectively. Similarly, the transient signal propagation characteristics, such as arrival time of the pulse, rise-time, delay time, settling time, etc. are influenced by the anisotropy in the transmission line and said information's are also important for proper characterization of analog/ digital pulses on multilayer iso/anisotropic substrate planar transmission lines. The time-domain characteristic of transient pulses over microstrip stepped line with diverse conditions are strengthening the concept of interconnects, which plays a vital role in modern circuit technology. Proposed modeling concept is more accurate to design of contemporary planar microwave filters, impedance matching networks and VLSI interconnects.
