The hybrid analysis of mode matching/FEM (MM/FEM) is applied to a waveguide short-slot 2-plane coupler. The analysis model is reduced to the one-eighth model by considering the three-dimensional structural symmetry. The analysis results agree well with those by HFSS.
In this paper, an ultra-compact Ultra-wideband (UWB) bandpass filter (BPF) based on modified multimode resonator (MMR) is proposed. The compactness of the proposed UWB BPF with good impedance matching in passband is achieved using modified MMR, which consists of meandered coupled lines, stepped-impedance stubs, open-circuited stubs and coupled-line sections. Stepped-impedance stubs which are used...
A single layer non-contact coupling transmission line for on-body applications at 2.45 GHz is presented in this paper. The transmission line consists of units in series, and each unit functions as a band-pass filter or a two-side coupled half-wavelength resonator. The segmented coplanar waveguide is applied to make the transmission line have only a conductive layer. An advantage of the transmission...
This paper proposes a small CRPA array with frequency-insensitive properties. The array consists of seven elements, and each element is composed of upper and lower circular loops that are designed to resonate at 1.575 GHz and 1.227 GHz, respectively. The lower loop is fed by the hybrid chip coupler, and the upper loop is electromagnetically coupled for a frequency-insensitive feeding mechanism. Due...
To design antennas for underwater communication systems using LF band, the transmission factor of dipole antennas with the sheath immersed in seawater are investigated by numerical study. Comparison of antenna characteristics between dipole antennas with different sheath structure is presented.
This paper deals with the development of compact square-loop-resonator (SLR) bandpass filter (BPF) with cross-shaped input/output (I/O) coupling. The proposed filter is designed for X-band frequency application with the center frequency of 9GHz and the −3dB fractional bandwidth larger than 4%. It is deployed on a 1.9mm thick high permittivity RT/duroid® 6010.2LM dielectric substrate with the dimension...
Wireless power transfer (WPT) is expected to spread around the world. WPT has two types, one is magnetic induction and another is magnetic resonant coupling (MRC). In magnetic induction, the amount of received power is determined by the transfer distance and the amount of magnetic flux through receiving coil. Therefore in transferring power to multiple receivers at each fixed transfer distance, power...
