This paper presents a ground-breaking triple-bandpass filter design utilizing modified T-shape rectangular coupled with stepped impedance resonator (MTSR-CSIR) for smart portable communication device applications. The MTSR-CSIR operates at (2.2, 3.62 and 4.6) GHz, providing wide passbands in three operating modes. To achieve the optimal performance, is executed on multi-layered liquid-crystal p...

The variable spacing parallel plate resonator ~VSPPR! is a microwave transmission line resonator with a continuously variable thickness of the dielectric spacer between the superconducting or metallic plates, filled by cryogenic liquid or vacuum. We measure the dielectric spacer thickness dependencies of the resonator frequency and quality factor, and fit them to theoretical forms, in order to ...

The existing work concentrates in Coarse Wavelength Division Multiplexing and few filters reported with non-uniform channel spacing, low quality factor. proposed ADF enhances the factor using Rounded Square Ring Resonator (RSRR) ensuring efficient bandwidth supporting WDM systems. des...

A novel elliptical patch resonator for a compact bandpass filter with tunable bandwidth is presented. This bandpass filter has the advantage of great flexibility in which the center frequency can be changed easily. The bandwidth of this filter can be modified by simply changing one variable, and this makes the proposed design unique. The order of the elliptical patch resonator can be increased,...

A new class of a dual mode microstrip fractal resonator is proposed and developed for miniaturization of the dual band bandpass filter. The perimeter of the proposed resonator is increased by employing fourth iteration T-square fractal shape. Consequently the lower resonant frequency of the filter is decreased without increasing the usable space. The self similarity of the usable structure enab...

We theoretically and experimentally investigate the multipolar hybrid plasmon-photon modes supported by a dielectric-metal core-shell resonator consisting of a dielectric core wrapped by a thin silver shell and the whispering-gallery modes in its pure dielectric counterpart (the dielectric sphere with the same size). We theoretically demonstrate that in a certain wavelength range the achievable...

A new shaped circularly polarized dielectric resonator antenna (CP DRA) is studied with branch-line coupler and log-periodic balun for the GPS application. Since the coupler and balun are located under the DRA, it does not increase the footprint of the antenna, as a result the system is very compact. Two configurations are considered in this paper. In the first configuration, an external 50Ω lo...
