Autor: Zehentner, Ján; Mrkvica, Jan; Macháč, Jan
(IEEE, 2005-06)This paper presents an analysis of a flat slotted waveguide by the spectral domain method finalized by a complex root search procedure. Matching of fields from bounded and unbounded regions at the common interface is ... -
Leaky Wave Radiation of a Printed Slotline Antenna
Autor: Zehentner, Ján; Macháč, Jan; Lorenz, Petr; Mrkvica, Jan
(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 ... -
Modes on the Standard and Inverted Conductor-Backed Slotline
Autor: Zehentner, Ján; Macháč, Jan; Mrkvica, Jan; Tuzi, Carlo
(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 ... -
Novel Selected Modes on the Conductor - Backed Slotline
