Field coupling to nonuniform coupled microstrip transmission lines
International Journal of RF and Microwave Computer-Aided Engineering, 2003An efficient method for frequency-domain and transient analysis of the nonuniform lossless coupled microstrip transmission lines excited by external electromagnetic waves is presented. The nonuniform coupled microstrip transmission lines system is first decomposed into a large number of uniform sections called steplines.

The surge coupling to transmission lines
IEEE Antennas and Propagation Society International Symposium. 1996 Digest, 2002In this paper, the surge coupling characteristics on a lossy transmission line are discussed. The rules of using the Laplace transformation are given. Discussions about the characteristics of time signals on a transmission line are given. The time domain solution is discussed.

Planar transmission line transformer using coupled microstrip lines
1998 IEEE MTT-S International Microwave Symposium Digest (Cat. No.98CH36192), 2002A novel and simple configuration of the planar transmission line transformer using coupled microstrip lines is proposed. A design methodology is also presented. The simulated and measured results demonstrate broadband impedance transformation with good efficiency for RF and microwave circuit design.

Experimental Characterisations of Coupled Transmission Lines
4th IEEE International Symposium on Electronic Design, Test and Applications (delta 2008), 2008Coupled transmission lines are experimentally characterised by using 4-port s-parameter measurements in the broad frequency band (up to more than the 20 GHz). The test patterns are designed and fabricated by using a BGA package process. Symmetrical coupled transmission lines are decoupled into two eigen modes that can be readily determined from the ...

New model of coupled transmission lines
IEEE Transactions on Microwave Theory and Techniques, 1995The paper shows that an existing description of coupled transmission lines is inconsistent and proposes a new model based truly on the mutual coupling concept. In the existing formulation a series electric coupling and parallel magnetic coupling are combined. In the new formulation the parallel electric and magnetic couplings as well as series electric

Field-to-transmission line coupling models
2020This chapter presents the coupling of lightning electromagnetic fields to overhead and underground lines based on the transmission line approximation. The chapter starts with an introductory section in which the advantages and the drawbacks of three approaches, namely the quasi-static approach, the transmission line approach, and the antenna approach ...

Radiation from coupled multiconductor transmission lines
IEE Proceedings - Generation, Transmission and Distribution, 2003Based on the reciprocity theorem, a simple method for analysis of the radiated electromagnetic fields from an arbitary configuration of coupled multiconductor transmission lines with linear terminations is presented. The radiation problem is solved using the reciprocity theorem and the solution of the coupling problem.
