Planar Transmission Lines in MW and MMW Circuits
(IEEE, 2005-09)The analysis of open, particularly slotted planar transmission lines in a wide frequency range is presented in this paper. The full wave approach by the spectral domain method is applied. Theoretical findings and their ... -
Visualization of leaky waves on planar transmission lines
(IEEE, 2004-05)This paper presents a visualization of leaky waves excited by delta-gap sources on planar transmission lines, namely the 2nd surface and space leaky modes on the slotline, and the dominant and surface leaky modes on the ... -
Modes on the Standard and Inverted Conductor-Backed Slotline
(IEEE, 2003-06)This paper recalls modes which can propagate on the conductor-backed slotline. The characteristic of the dominant mode on the CBSL is documented. The ICBSL is a modification of the CBSL placed in a dielectric with permittivity ... -
The Inverted Conductor-Backed Slotline - a Challenge to Antenna and Circuit Design
(IEEE, 2003-10)The characteristics of modes on the conductor-backed slotline, the inverted conductor-backed slotline and on its modification in which the top dielectric layer with higher permittivity has a finite thickness, are presented ... -
Novel Selected Modes on the Conductor - Backed Slotline
(IEEE, 2002)This paper presents a detailed full-wave analysis of the conductor-backed slotline. The occurrence of an even dominant mode is revealed. This mode may propagate alone from dc up to the frequency at which the first leaky ... -
Wide-Slotted Printed Slotline Radiator
(IEEE, 2002)This paper summarizes the investigation of radiation from the slotline made on a thin low permittivity substrate. The slot radiates the space leaky wave of the first order. The dispersion characteristic of this wave is ... -

Comments on Representation of Surface Leaky Waves on Uniplanar Transmission Lines
(IEEE, 2002-02)This paper compares partial waves approximating a surface leaky wave on a uniplanar transmission line with substrate surface waves supported by its substrate. It is shown that their field distributions and the propagation ... -
Leaky Wave Radiation of a Printed Slotline Antenna
(IEEE, 2001)This paper presents a theoretical prediction of the field radiated from a uniplanar slotline antenna operating with the leaky wave. Discussion on a possible spectrum of space leaky waves is opened. Several antennas and ... -

New Space Leaky Wave Spectrum Components on the Slotline
(IEEE, 2000-10)Surface and space leakage of power deteriorates the operation of circuits. On the other hand space leaky waves enable the design of specific radiators. In this paper we therefore investigate the potential of the slotline ... -
Space Leakage of Power from the Slotline
(IEEE, 2001)In this paper we present the comprehensive dispersion characteristics of the slotline on thin and low permittivity substrate with a wide slotwidth comprising the bound and space leaky waves with even and odd electric field ... -
Space leakage of power from uniplanar transmission lines
(IEEE, 2000)Surface and space leakage of power deteriorates the operation of circuits. On the other hand space leaky waves enable the design of specific radiators. We therefore investigate the potential of the slotline and the coplanar ... -
Dispersion characteristics of leaky waves on lossless and lossy slotlines
(IEEE, 1998-06)This paper deals with the dependence of the type of solution of the determinantal slotline dispersion equation on the location of the poles of its matrix elements. A number of possible solutions above the cut-off frequencies ... -
Load Impedances of Complex Slotline Terminations
(IEEE, 1995-09)Single slotline has gained new interest due to application in uniplanar circuits, antennas or active radiators, all these including slotline short circuits or even more complex terminations. This paper gives a new approach ... -
Surface leaky waves and their measurement
(IEEE, 1998-10)A new approach to experimental identification of surface leaky waves on printed-circuit lines is presented in this paper. Active radiometry is used for field probing even in the near field zone. The measurement is adjusted ... -
Leakage Effects of Dominant and Higher Order Modes on Slotline
(IEEE, 1996-09)The properties of the slotline when the dominant bound or leaky wave propagates, together with the behaviour of new higher order modes are investigated. The frequency range in which the slotline transmits the bound wave ... -
Short and Open Circuited Slot Line
(IEEE, 1995-07)A slot line terminated by the short and open end is analysed by the spectral domain method (SDM). The original process of Yang and Alexopoulos (1988) is modified by application of the piecewise sinusoidal functions only. ... -
On the design of waveguide-to-microstrip and waveguide-to-coplanar line transitions
(IEEE, 1993-09)New versions of the waveguide-to-microstrip and waveguide-to-coplanar line transitions are described and analyzed. The transitions differ from the standard ones by a probe in the shape of a rectangular patch. The structure ...
