Complementary 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 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 کاملMulti-gap individual and coupled split-ring resonator structures.
We present a systematic numerical study, validated by accompanied experimental data, of individual and coupled split ring resonators (SRRs) of a single rectangular ring with one, two and four gaps. We discuss the behavior of the magnetic resonance frequency, the magnetic field and the currents in the SRRs, as one goes from a single SRR to strongly interacting SRR pairs in the SRR plane. We show...
متن کاملDirect Experimental Observation of Pulse Temporal Behavior in Integrated-Optical Ring-Resonator with Negative Group Velocity
We report a direct experimental observation of pulse temporal behavior in an integrated optical two-port ring-resonator circuit as a function of coupling strength, including the transition across the critical coupling point. We demonstrate the observation of pulse ‘advancement’ in the negative vg regime and pulse delay in the positive vg regime. We also observed a smooth transition of the pulse...
متن کاملA Novel Symmetrical Split Ring Resonator Based on Microstrip for Microwave Sensors
In this paper, novel symmetrical split ring resonator (SSRR) is proposed as a suitable component for performance enhancement of microwave sensors. SSRR has been employed for enhancing the insertion loss of the microwave sensors. Using the same device area, we can achieve a high Q-factor of 141.54 from the periphery enhancement using Quasi-linear coupling SSRR, whereas loose coupling SSRR can ac...
