  • Patent number: 11211912
    Abstract: A noise filter includes a first capacitor and a second capacitor which are two line-to-line capacitors. Currents flowing through the first capacitor and the second capacitor are in directions opposite to each other, and meanwhile, currents flowing through a first connection wire and a second connection wire are in the same direction and parallel to each other. Accordingly, magnetic coupling is caused between the connection wires and the line-to-line capacitors. Thus, the residual inductance of a line-to-line capacitor itself is reduced, whereby an attenuation characteristic for normal mode noise is further improved.

  • Patent number: 10361481
    Abstract: Inter-element couplings between radiative elements of an antenna can be reduced by increasing resonant frequencies for first selected radiative elements and decreasing resonant frequencies for second selected radiative elements. In some approaches, the radiative elements are coupled to a waveguide and the antenna configuration is a hologram that relates a reference wave of the waveguide to a radiated wave of the antenna. In some approaches, the antenna configuration is modified by identifying stationary points of the hologram and then staggering resonant frequencies for radiative elements within neighborhoods of the stationary points.
