Abstract Based on the excitation theory of L.A. Vainstein obtained simple and convenient iterative relations for a resonator in form rectangular parallelepiped with dielectric layer through several coupling windows its walls. Theexpansion field terms complete system solenoidal functions is used. Solenoidality due to fact that electric fields openings waveguides walls, fed coaxial-waveguide tran...

This paper discusses an elliptical ultrawideband (UWB) antenna and a dual-band UWB notch antenna. To achieve bandwidth, two corner cuts are etched into the rectangular slot on partial ground plane. An inverted-U-shaped conductor-shaped resonator utilized to characteristics The suggested has overall dimension of 24×32 mm2. gain 4.9 dB, bandwidth 2.5–11 GHz, linear phase response, group delay les...

The substrate integrated waveguide (SIW) structure is the candidate for many application in microwave, terahertz and millimeter wave application. It because of SIW can integrate with any component one than others structure. A kind components using a filter component, especialy bandpass filter. This research recommended rectangular open loop resonator giving more selectivity be implemented short...

A Wideband Rectangular Dielectric Resonator Antenna (RDRA) is presented in this manuscript. The proposed RDRA designed for wideband body area network (WBAN) applications due to its compact size and characteristics. antenna can be effectively integrated with modern medical devices transmitting biological signals. WBAN attract variety of monitoring human health the domains such as sports, enterta...

The merging of Microelectromechanical (MEM) devices and optics to create Microoptoelectromechanical (MOEM) systems provides opportunity to create new devices and to expand the functionality and applications of MEMS technology. Planar optical waveguide co-integration with surface micromachined (SMM) structures and inclusion of diffractive optical systems within 3-D MEMS chip stack architectures ...

A dual-band bandpass filter with wide and highly attenuated stopbands is designed using parallel coupled microstrip line (PCML) and stepped-impedance-resonators (SIRs). The proposed filter is composed of a pair of highly coupled PCML-SIR structure and a central resonator using a low impedance rectangular microstrip. Initially, the wide dual-band performance is achieved by creating a transmissio...
