A novel synthesis method for a class of time-domain passive filters that compensates for waveform distortion caused by frequency dependencies of the transmission properties of signal propagation paths, is formulated. The method is based on the linear response theory and mathematical properties of scattering matrices for passive circuits. This paper...

... begin by defining a signal propagation path to be compensated for by a PPCF. As shown in Fig. 5, the path is a two-port radio propagation path that is designated by two antenna ports placed at a pair of identical oval-dipole antennas 6 m apart in free space, facing each other. Since the boresight direction of the antenna is normal to the substrate plane and the polarization direction of the emitted waves is parallel to the major ...

... path that is designated by two antenna ports placed at a pair of identical oval-dipole antennas 6 m apart in free space, facing each other. Since the boresight direction of the antenna is normal to the substrate plane and the polarization direction of the emitted waves is parallel to the major axis of the elliptical pattern composing the antenna, Fig. 5 shows that both antennas are set up to maximize the received power. Since this propagation system is in free space and has no multipath signal, the nonuniformity of signal transmission properties is only due to the antennas' radiation dispersion and the distance attenuation. Details of the antennas are given in Fig. 6. The ...
