f Multilayer band pass filter By www.freepatentsonline.com Published On :: Tue, 19 May 2015 08:00:00 EDT In a multilayer band pass filter, via-electrodes and strip electrodes define inductors of LC parallel resonators in four stages. A capacitor electrode and a ground electrode define a capacitor of a first-stage LC parallel resonator. A capacitor electrode and the ground electrode define a capacitor of a fourth-stage LC parallel resonator. Capacitor electrodes define a second-stage LC parallel resonator. Capacitor electrodes define a third-stage LC parallel resonator. Among four or more of the LC parallel resonators, the coupling between certain LC parallel resonators is easily defined, and the attenuation characteristic of a filter is definable with a high degree of freedom.

f Quarter wave plate polarizer with two phase-shifting portions By www.freepatentsonline.com Published On :: Tue, 19 May 2015 08:00:00 EDT A right circular cylindrical body of an isotropic dielectric such as a cross-linked styrene copolymer, has respective pluralities of mutually parallel grooves formed in its axial end faces, spaced apart by an intermediate portion whose dimension c is a half wavelength. The axial lengths a, b of the grooves are such that when a wave passes through the body, a quarter wavelength phase difference is produced between a component of a wave having its E-vector parallel to the grooves and a component of the wave having its E-vector orthogonal to the grooves. Alternatively the plate may consist of two or more discrete bodies whose grooves are dimensioned to produce a total differential phase shift of one quarter wavelength. Full Article
