Microstrip Coupler with Complementary Split-Ring Resonator (CSRR)
نویسندگان
چکیده
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 coupling) over a wide frequency band (26.3% relative bandwidth). Keywords— Microstrip double-line coupler, CSRR

Design and Implementation of Multi-Band Hybrid Coupler with Arbitrary Power Division
Patch hybrid couplers are used to provide arbitrary power division ratio over two frequency bands. The coupler is designed using three main topologies. They are Branch-line, Coupled-line and Patch. Branch-line and Coupled-line provides equal power division ratio over two frequency bands. Patch structure provides arbitrary power division ratios. The patch hybrid coupler is the rapid development ...
متن کاملComplementary Split Ring Resonator Effects on Radiation Pattern Reconfigurable Circular Microstrip Antennas
In this study, a radiation pattern reconfigurable microstrip antenna is designed and fabricated. The antenna’s radiation pattern is directed in 9 different angles by employing a radiating patch and embedding complementary split ring resonators (CSRR) on the ground plane. The radiating patch is of circular shape, while for CSRR elements both circular and rectangular shapes are investigated. The ...
متن کاملA Compact Ultra-Wideband Bandpass Filter with Sharp-Rejection using Complementary Split Ring Resonators
A compact and sharp-rejection ultra-wideband (UWB) microstrip band-pass filter (BPF) is developed using of left handed metamaterials realized by complementary split ring resonator (CSRR). Moreover, proposed structure consists of two doublets parallel coupling gaps at each side of a microstrip ring. In comparison with some other filters, this structure shows a significantly wider passband due to...
متن کاملA Microstrip Highpass Filter with Complementary Split Ring Resonators
An accurate equivalent circuit model for the microstrip line with a complementary split ring resonator (CSRR), and the parameter extraction method, are presented. A highpass filter with steep rejection is designed based on the model.

متن کاملA Miniaturized Directional Coupler Using Complementary Split Ring Resonator and Dumbbell-Like Defected Ground Structure
A novel microstrip coupled-line directional coupler is proposed in this paper. It is based on the introduction of a complementary split ring resonator and dumbbell-like defected ground structure on the coupled lines to strongly enhance the designed backward coupling. The designed frequency band is from 1.2 to 1.5GHz. The coupler is fabricated and tested. The insertion loss is less than 3.5 dB. ...
