AbstractCharacteristics of uniplanar feed topologies for the dielectric resonator antenna (DRA) based on the CPW are presented. The dual‐resonance characteristics of the capacitive feed are discussed. A comparison of the CPW capacitive, square‐loop, and inductive feeds shows that the real‐estate requirements and radiation patterns are strongly ...

This paper derives simple CAD formulas of three common types of MIC lines: microstrip, CPW (coplanar waveguides) without and with a backing conducting plane. It shows that both the analysis and design formula pair can be derived from the same novel technique of synthetic asymptote.

A Broadband Microstrip-to-CPW Transition
2005 Asia-Pacific Microwave Conference Proceedings, 2006A broadband microstrip-to-coplanar waveguide transition (CPW) is proposed in this paper. The ground shaping technique, which emphasizes the field matching, is employed in our proposed design. The shape of the backed ground plane varies gradually which can result in a smooth field transition.

This paper presents a novel MEMS coplanar microwave waveguide (CPW) structure. The high-resistivity silicon is chosen as the material of substrate and the aluminum is as the metal transmission line because of its high conductivity ,Removing the silicon between the signal line and ground line, underneath the edge of both line,these can effectly reduce ...

A micromachined tunable CPW resonator
2001 IEEE MTT-S International Microwave Sympsoium Digest (Cat. No.01CH37157), 2002This paper presents a novel tunable microwave resonator, consisting of a CPW spiral inductor with a cantilever interconnect structure. Tuning was achieved by applying a DC bias between the input and output of the resonator circuit. An observable resonance tuning between 3 and 7 GHz was accomplished by applying a bias from 0 to 40 V.

Improved CPW to slotline transitions
1996 IEEE MTT-S International Microwave Symposium Digest, 2002The paper presents a new approach for designing an ultra broadband coplanar to slotline transition. The procedure is carried out in three steps: design, modeling and fabrication of two new broadband uniplanar CPW to slotline transitions, in the 1 GHz to 50 GHz frequency range. The advantages of these transitions are discussed.

CPW Cascaded Magnetostatic Wave Band Stop Resonators
INTERMAG 2006 - IEEE International Magnetics Conference, 2006Magnetostatic-wave resonators in bandstop configuration have been studied by using a coplanar waveguide transmission line to excite the resonating signal. The microwave performances of such a device have been discussed and implemented by using cascaded resonators, to improve the micro wave absorption and the selectivity response of the entire structure.

In this letter, a new design for a planar antenna is introduced. The antenna is built using coplanar technology. It has dual-frequency operation: the first and second resonances are in the X- and Ku-bands, respectively. The proposed antenna has wideband behavior around both resonance frequencies.

The Effect of Mitering on CPW Discontinuities
21st European Microwave Conference, 1991, 1991The effect of mitering on coplanar waveguide (CPW) discontinuities is studied using a full wave space domain integral equation method which is discussed briefly. Preliminary results for a mitered CPW open-end are presented. The discretization mechanism used in the method of moments and its effect on the convergence is also outlined and a sample ...
