Over Layer Sensing Using Terahertz Meta-Material Split Ring Resonator

Improved Split - Ring Resonator for Microfluidic Sensing

We present a method of making low loss split-ring resonators for microfluidic sensing at microwave frequencies using silver coated copper wire. We show that a simple geometric modification and the use of square cross-section wire give greater electric field confinement in the capacitive region of the resonant sensor. We use a combination of theoretical analysis, finite element simulations and e...

Notched UWB bandpass filter using complementary single split ring resonator

In this paper, a simple method to obtain a notch in the ultra-wideband (UWB) bandpass filter is presented. UWB bandpass filter is designed using ground plane aperture technique. To reject the undesired wireless local area network (WLAN) signals, a complementary single split ring resonator (CSSRR) is placed under the coupled lines of the bandpass filter. The CSSRR has flat insertion loss and goo...

Frequency Switching of PIFA Using Split Ring Resonator

In this paper, a PIFA loaded with split ring resonator (SRR) is presented, in which frequency switching is performed by varying the radius of split rings. The proposed Planar invertedF antenna (PIFA) without metamaterial resonates at 7.46 GHz with return loss of -23.71 dB, gain value 5.41 dBi and bandwidth 361.8 MHz. Proposed PIFA structures with metamaterial loading resonates at multiple frequ...

Design of Hexagonal Split Ring Resonator using HFSS

In this paper, Hexagonal Split Ring Resonator (HSRR) and Square Split Ring Resonator (SSRR) are designed using HFSS simulation software. Both split ring resonators are based on the Metamaterial and same parameters. Then after compare the simulation result of HSRR and SSRR. HFSS simulation of the Hexagonal SRR shows improved Return Loss and VSWR i.e. -44.7 dB and 1 respectively compare to Square...
