Design of Multiband PIFA loaded with Split Ring Resonator

In this paper, a multiband planar inverted-F antenna (PIFA) with high gain and appreciable bandwidth at the resonant frequencies is designed using metamaterial concept. The proposed PIFA without metamaterial is designed to resonate at 7.46 GHz with return loss of -23.71 dB and gain value 5.41 dBi. The designed antenna is having maximum possible bandwidth of 361.8 MHz. The proposed PIFA with spl...

The Propagation and Cutoff Frequencies of the Rectangular Metallic Waveguide Par- Tially Filled with Metamaterial Multilayer Slabs

In this paper, the wave propagation and the cutoff frequencies of a rectangular metallic waveguide, partially filled the metamaterial multilayer slabs have been studied. The equations of the TMM method are not complex and the numerical examples show that we can easily obtain the characteristics of the metamaterial multilayer’s rectangular waveguide satisfyingly. The cutoff frequencies of the me...

Complementary Split-Ring Resonator-Loaded Microfluidic Ethanol Chemical Sensor

In this paper, a complementary split-ring resonator (CSRR)-loaded patch is proposed as a microfluidic ethanol chemical sensor. The primary objective of this chemical sensor is to detect ethanol's concentration. First, two tightly coupled concentric CSRRs loaded on a patch are realized on a Rogers RT/Duroid 5870 substrate, and then a microfluidic channel engraved on polydimethylsiloxane (PDMS) i...

On-chip waveguide resonator with metallic mirrors.

We introduce an optical microresonator consisting of a planar waveguide terminated by metallic mirrors. The resonator was fabricated on a silicon-on-insulator platform, and its optical performance was theoretically and experimentally investigated. The demonstrated device had dimensions of 200 mumx40 mum and exhibited a quality factor of about 1000 and a free-spectral range of about 8 nm. Applic...
