“…Like in many transitions for other planar waveguides, transitions for CBCPWs have been mainly studied in relation to other planar transmission geometries [1]- [4]. On much rarer occasions, transitions from planar transmission lines in the vertical direction of the substrates are discussed.…”

A wideband vertical transition between conductorbacked coplanar waveguide (CBCPW) and parallel-strip (PS) transmission line is presented. By choosing the same widths for the two conductor strips comprising the PS transmission line, the transition performs unbalanced-to-balanced transformation as well. Back-to-back configurations of the transition have been realized and their transmission, reflection, and direct-coupling characteristics have been measured. It is shown that the placement of vias connecting the top and the bottom grounds of the CBCPW along the entire gap between the truncated center conductor and the ground is crucial in preventing spurious resonances of the CBCPW structure. The fabricated back-to-back transition features low insertion loss over the 28:1 frequency range that has been tested.

“…In‐ and out‐of‐phase power dividers that use half‐ or quarter‐wavelength TL sections, such as those in, 2‐8 are not only large in size but also their bandwidths are limited to the bandwidth of the utilized TL sections. To address these issues, several techniques for the design of ultra‐wideband power dividers have been reported in the literature 9‐12 . However, the fabrication procedure of those structures is complex since they are based on multilayer substrates, 9,10 via holes, 11 or air‐bridges and bond wires 12 .…”

A multi-section ultra-wideband Wilkinson power divider is presented in this article. The proposed device is developed based on a coplanar waveguide (CPW) to coplanar strip (CPS) transition, which is realized on a two-layer printed circuit board without using via holes. Equivalent circuit model of the proposed power divider is presented, and on that basis a three-section power divider with an ultra-wideband performance, ranging from 3 to 16 GHz is designed and numerically validated. Finally, prototypes of the proposed device is fabricated and measured to provide an experimental verification on the numerically predicted features, namely the operating bandwidth, input/output impedance matching, insertion loss, isolation between output ports, and amplitude/phase balance at output ports.

“…However, via holes increase the complexity of the fabrication and reduce the yield of products. The use of multiple layer substrates (MLS) on top or bottom of CPW will eliminate the leakage of the energy from the dominant modes [13], but implementation of MSL is challenge in bonding different substrates, and it also increases the loss and thickness of the substrate. The methods such as channelized coplanar waveguide (CCPW) in [14] can suppress the parallel plate modes by electrically connecting side walls s pnuougrapni Ut penGU ualnU Siup 111lt * Substrate Metal to the bottom conductor.…”

A novel band stop filter with mutually coupled dual spiral configuration on conductor-backed coplanar waveguide (CBCPW) is proposed and investigated. A circuit model is introduced to investigate the characteristics of proposed circuits. The model-based results, full-wave EM simulation results and the experiment results are matched well. The periodic band stop filters are designed and fabricated by using thin-film technology. The size of filter is only 2.3 mmxI.o mm.
