NEW MICROSTRIP TRANSMISSION LINES FOR MICROWAVE INTEGRATED CIRCUITS K. Sachse, A. Sawicki ABSTRACT The paper discusses the properties of new microstrip transmission lines using a slot in the ground-plane. These lines have high characteristic impedance and their attenuation and frequency dispersion as well are small. A very tightly coupled cross-section of microstrip lines may be constructe

FIELD DESORIPTION FOR MULTI-SLOT FIN-LINE STRUOTURES Abdel Megid Kamal Saad and Klaus Schunemann Abstract: A generalized fin-line structure is analyzed, which shows several slots in the metal coating of the substrate. Possible applications of such a structure are e.g. directional couplers and 3 dB hybrids. Out-off frequencies, phase constants, and electric and magnetic field patterns are calcu

GUIDING CHARACTERISTICS AND RADIATION CHARACTERISTICS OF PLANAR WAVEGUIDES Helmut Ermert ABSTRACT Planar waveguides like microstrip and microslot have been used not only as waveguides but also for radiation purposes (microstrip antenna). Therefore, the paper tries to give a clear description of waveguide characteristics as well as radiation characteristics of planar waveguides. The difference

CONTINUOUS EIGENVALUE TERMINATIONS A. Henderson and J.R. MODE SPECTRUM ANALYSIS OF MICROSTRIP OPEN-CIRCUIT James ABSTRACT A new analysis of the open-circuit microstrip termination is described which enables all of the reflection, transmission, radiation and surface wave effects to be calculated. The formulation is based on a continuous eigenvalue mode spectrum and provides the most complete t

COUPLED-LINE DIRECTIONAL COUPLERS FOR M.I.C. M. HOUDART * ABSTRACT --- Following a general consideration of the concept of directional couplers in an inhomogeneous medium and physically asymmetrical couplers, this paper reviews various new types of MIC couplers carring, sometimes simultaneously, different propagation modes (microstrip, coplanar line, slot 1ine). Experimental results are pres

GBit/s-PULSE PROPAGATION IN MICROSTRIP DISCONTINUITIES Wolfgang Menzel ABSTRACT: In the last years, a variety of microstrip discontinuities have been analysed using a waveguide model with frequency dependent parameters. This contribution shows an application of these calculation techniques to fast digital signal analysis of baseband and carrier frequency circuits in microstrip. The signals a

PSEUDO RANDOM SEQUENCE AND PROGRAMMABLE WORD GENERATORS UP TO 10 GBIT/S R. Schwarte, R. Sinning ABSTRACT B. Brinkmeier, J. Fischer, H. Koppenhofer, K.H. Narzinski, A word generator concept based upon the SSL-principle (Series-gate Sampling Line) has been found to provide the highest bit rate in pseudo-random and programmable word generation so far experimentally attained.
