The Distributed Oscillator at 4 GHz
(IEEE, 1998-12)This paper describes the design and experimental verification of a tunable oscillator based on a microwave distributed amplifier. The oscillator met design expectations, being capable of continuous tuning over the range ... -
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 ... -
Triple Wire Medium for Use in Isotropic Metamaterials
(IEEE, 2007-10)In this paper a triple wire medium is described as an isotropic negative permittivity medium. A numerical experiment was performed to validate the propagation of electromagnetic waves inside the wire lattice below the ... -
Upper Cut-Off Frequency of the Bound Wave and New Leaky Wave on the Slotline
(IEEE, 1997-06)This paper contributes to a more profound understanding of uniplanar circuit behaviour. A simple closed-form formula providing the upper cut-off frequency of the bound wave propagating over the slotline is presented. A new ... -
Use of Nano-Grids in a Waveguide
(IEEE, 2006-09)A new concept of passive waveguide circuits is presented. It is based on a combination of the standard rectangular waveguide with a metal uniform linear polarization grid of nano thickness. The grid is deposited on a polymer ... -
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 ... -
Waveguide bandpass filters with attenuation of higher-order passbands
(IEEE, 1993-09)A new method is proposed to provide additional attenuation to higher-order passbands of metal waveguide bandpass filters. To this end, shunt waveguide sections with cut-off frequencies are included into the filter structure. ... -
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 ... -
Wideband VIP power divider with differential output
(IEEE, 2003-12)A novel wideband VIP power divider with out of phase outputs was designed and experimentally verified. The phase difference 180° ±5° and the amplitude difference ± 0.8 dB of output signals were achieved in 4-26 GHz frequency ...
