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 presents characteristics of a free access transmission line consisting of a paper substrate and foam instead of dielectric substrate for easy installation in body area network applications. We measure the coupling characteristics between two dipole antennas above the proposed transmission line to show its basic performance. The coupling level between two dipole antennas on body propagation...
We presents characteristics of a free access transmission line consisting of a paper substrate and foam instead of dielectric substrate for easy installation in body area network applications. In this paper, we simulated the coupling characteristics between two dipole antennas above the proposed transmission line to show its basic performance. The average of coupling characteristics above the transmission...
Wireless power transmission (WPT) by two short helical dipoles arrayed orthogonally is presented. For the electric resonance coupling WPT system, the short dipoles need for a matching circuit due to cancel its large capacitance at the operating frequency. In the proposed method, the loss is reduced by using the helical structure instead of matching circuit. Its power transmission characteristics are...
In the wireless power transmission (WPT), the freedom of antenna's position is one of the important things. In the WPT systems using the magnetic resonance, the angle characteristic of two rectangular coils has been reported [1]. Furthermore, the study about the efficiency improvement by a transmission coil array for the decreasing of efficiency due to antenna position has been proposed [2]. Although...
