NOVEL MICROSTRIP CIRCULAR PATCH ANTENNAS
NOVEL MICROSTRIP CIRCULAR PATCH ANTENNAS S.MELLAH, M.DRISSI and J.CITERNE INSAlLCST.CNRS, URA 834, 20 Avenue des Buttes de Coesmes . 35043 Rennes Cedex FRANCE ABSTRACT Two new microstrip circular patches excited by a microstrip transmission line through an inserted coplanar section are presented. The integral equation for the unknown currents on the antenna and its feeding line is solved by

MODELLING NONLINEAR DISPERSIVE MEDIA IN 2D TLM
MODELLING NONLINEAR DISPERSIVE MEDIA IN 2D TLM Leonardo R.A.X. de Menezes and Wolfgang J. R. Hoefer * "" " ABSTRACT: This paper describes the modelling of nonlinear dispersive media in a two-dimensional TLM mesh. The nonlinear medium behavior is represented by connecting a one-port nonlinear network to each node in the mesh (shunt or series). Using this approach the propagation of electromagnet

MODELING OF REGULAR CONDUCTING AND SUPERCONDUCTING BOUNDARIES IN TLM
MODELING OF REGULAR CONDUCTING AND SUPERCONDUCTING BOUNDARIES IN TLM Jahn Damaschke * and Wolfgang J. R. Hoefer * ABSTRACT Several models have been developed, implemented and tested in TLM that describe the time domain behavior of lossy conducting walls with their dispersive and nonlinear characteristics over a wide frequency range. These models thus accurately represent the properties of regular
