Sensors and Actuators A: Physical, 2018
Abstract Printing high-resolution microwave passive devices directly on textile surfaces presents many challenges due to the high surface roughness and porosity of textile materials. This paper explains in detail physical and electromagnetic characterization of screen-printed coplanar waveguides (CPWs) on nonwoven textiles with a surface roughness of

Design a 3.5 slot antenna using coplanar waveguide (CPW) for dual band application
2013 Conference on Microwave Techniques (COMITE), 2013The proposed antenna is designed to overcome the demand in dual band issues. The basic shape structures of antenna are designed at frequency 2.4 GHz based on radiating structure 5 and 5.2 GHz based on radiating structure 3. Then, the changes on the position of radiating structure 3 have been carried out to investigate the effect for dual band.

A Compact Coplanar Waveguide (CPW)-Fed Zeroth-Order Resonant Filter for Bandpass Applications
Frequenz, 2017AbstractA new CPW-fed bandpass filter based on zeroth order resonant (ZOR) technique is presented in this paper. Proposed filter structure is designed on a CPW single layer where via is not required, hence reduces fabrication complexity. The property of metamaterial of ZOR has been utilized to reduce the filter size.

Comprehensive study of CAD models of several coplanar waveguide (CPW) discontinuities
IEE Proceedings - Microwaves, Antennas and Propagation, 2005A comprehensive study of CAD models of several coplanar waveguide (CPW) discontinuities is presented. The following discontinuities are studied: CPW short-end, CPW open-end, symmetric CPW series gap, and symmetric short-end coupled CPW. Simple models, that are suitable for CAD purposes, are proposed and validated by comparison to published full-wave ...

Investigation of Compact Tree-Shaped Coplanar Waveguide (CPW) Antenna for RF Energy Harvesting
Applied Mechanics and Materials, 2014This paper studies a compact wideband tree-shaped coplanar antenna which has the potential to be used for RF energy harvesting. The antenna is fabricated on a double-sided FR-4 printed circuit board using an etching technique. The effect of semi-circle patch embedded to a triangular patch has been studied.

Coplanar waveguide (CPW)‐FED circular slot antenna for W‐band and imaging system applications
Microwave and Optical Technology Letters, 2011AbstractUsing a coplanar waveguide (CPW) feed with a short‐circuiting stub, the fed circular slot antenna for W‐band operation is presented.The obtained results show that the impedance bandwidth, which is determined by 10 dB return‐loss of the proposed slot antenna, can reach to 21% with the center frequency at 94 GHz (80 GHz–100 GHz), and the gain ...

IEEE Sensors Journal, 2016
In this paper, a microwave displacement sensor that is based on electromagnetic bandgap structure is proposed. The periodic air holes realized in a silicon substrate cause bandgap in the transmission response of coplanar waveguide (CPW) line printed on this substrate.

IEEE Transactions on Microwave Theory and Techniques, 1994
This paper presents a novel analysis of air-bridges in open CPW, including the effects of finite thickness metallisation, using the complete modal spectrum of the CPW. This is a technique which, in comparison with other methods, allows the common features of CPW circuitry to be extracted and preprocessed without consideration of the particular problem ...

2005 IEEE Antennas and Propagation Society International Symposium, 2005
A three element CPW-CTS array antenna is described. The advantages of this new design include low cost, low profile, light weight, and a very simple planar microstrip feed configuration. The three element antenna exhibits a well-formed broadside main beam with up to 31% decrease in HPBW (compared to a single element CPW-CTS) at the 10 GHz frequency ...
