Simulation, Fabrication and Testing of a Left-handed Microstrip Coupler
نویسنده
چکیده
A broadband left-handed parallel-line microstrip coupler is implemented by both electromagnetic simulation and actual fabrication. The circuit dimensions are smaller and more compact than those in previous studies and a thinner Duroid substrate of thickness h 0.635 mm is used. Parametric studies were performed using IE3D, and fabrication was done via a Quick Circuit 7000 prototyping machine. The network-analyser measurements indicate broad bandwidth coupling in the 6.5–7.7-Ghz region. © 2005 Wiley Periodicals, Inc.

Forward coupling phenomena between artificial left-handed transmission lines
Coupling phenomena between artificial left-handed ~LH! transmission lines are explored on the basis of a transmission line approach of LH materials. A LH forward coupler in the form of an ideal lumped-element ladder network is presented and is shown to exhibit strong forward coupling that increases with decreasing of frequency. A quasi-lumped element microstrip implementation of a LH coupler is...
متن کاملDesign of a Novel 3 Db Microstrip Backward Wave Coupler Using Defected Ground Structure
In this paper an edge coupled microstrip coupler with defected ground structure is presented. A normally 7 dB coupler designed on Alumina substrate is converted into a 3 dB coupler by cutting single rectangular slot in the ground plane encompassing the two transmission lines. Other properties of backward wave coupler remain the same, except for a tighter coupling. With this method of design opt...
متن کاملMicrostrip Coupler with Complementary Split-Ring Resonator (CSRR)
A novel microstrip Coupler with Complementary SplitRing Resonator (CSRR) is simulated and fabricated. The CSRR structure in the grounded plane of a conventional microstrip double-line coupler, increases its even mode characteristic impedance. This results in a higher degree of coupling. The results of simulation and measurement show that the new coupler achieves a high degree of coupling (5 dB ...
متن کاملA Novel Broad Bandwidth and Compact Backward Coupler with High Coupling- Level
A novel backward microstrip coupled-line coupler which has been designed based on the metamaterial and composite right/left handed (CRLH) transmission line (TL) concepts is proposed. Coupling coefficient, bandwidth and size of proposed microstrip coupler are improved by coupled interdigital TLs which have been realized only by one interdigital capacitor. The design procedure to reach the couple...
متن کاملDesign and Simulation of Microstrip Directional Coupler with Tight Structure and High Directivity*
The design of Cyclotron CYCHU-10 has been carried out at Huazhong University of Science and Technology (HUST). Because of the low centre frequency (99MHz) of its RF system, we should choose suitable directional couplers for the RF system which is supposed to be highdirectivity and tight-structure. This paper analyzes and synthesizes kinds of directional couplers, especially microstrip structure...
