    Effects limiting the bandwidth of a double-Y balun that transforms a finite-ground-plane coplanar waveguide (CPWFGP) to a coplanar strip line (CPS) are investigated both theoretically and experimentally. Analysis shows two kinds of parasitic effects: parasitic effects that depend on the electrical length of the input transmission lines for the even and balanced modes, and those that dep...

  • Analytical investigation of electromagnetic waves in bianisotropic media

    Publication Year: 2001 , Page(s): 257 - 260

    An analytical investigation of the electromagnetic properties of bianisotropic media is presented. The chirality and permittivity tensors have nonzero off-diagonal elements. The analytical expressions of the wavenumbers are obtained for an arbitrary direction of the wave propagation. Two particular cases are studied: the wave propagation along the bianisotropy axis and the wave propagation normal ... View full abstract»

  • Design of broadband probe-fed plate antenna with stub

    Publication Year: 2001 , Page(s): 221 - 226
    Cited by:  Papers (8)

    A suspended probe-fed plate antenna with a stub is proposed for broadband applications. The radiating plate, which acts as a typical radiator, is designed based on standard rules for designing conventional microstrip antennas. The plate is suspended above a ground plane at a height of around 0.07 λ. Owing to the large spacing between the plate and ground plane, a coaxial probe is used to ex... View full abstract»

    A new type of on-glass vehicular antenna designed for application in the FM band is introduced and simulated radiation patterns are presented. Attention is paid to the car structure on which the antenna is mounted and an investigation is carried out into the dominant structural features of the vehicle body. The simulated patterns are compared with measurements View full abstract»

  • Fast analysis of bounces on power-/ground-planes

    Publication Year: 2001 , Page(s): 254 - 256

    A planar circuit model combined with an accelerating convergence algorithm is developed to analyse bounces on power-/ground-plane structures. The method presents fast convergence and high accuracy when compared with the planar circuit method and the FDTD method. The practicality of the method is demonstrated by performing bounce analysis of a lossy power-/ground-plane structure View full abstract»

    To investigate the electromagnetic radiation effects of holding a cellular phone, an anatomical model of the hand is introduced based on magnetic resonance imaging where 11 different tissues are recognised. A hand-held phone was placed close to an anatomical model of the head in the intended use position compliant with the European standard. A commercial dual-band GSM cellular phone was modelled i...

  • Novel approach for a design-oriented measurement-based fully scalable coplanar waveguide transmission line model

    Publication Year: 2001 , Page(s): 227 - 232

    A novel technique for constructing a design-oriented multi-layer coplanar waveguide (CPW) transmission line model is proposed. The technique uses a novel method to determine the conductive losses of an arbitrary CPW line, based on the losses of a limited set of measured reference lines, with a constant ground-to-ground spacing and a closed-form formula derived for standard CPW lines, to predict th...
