  • Patent number: 11456775
    Abstract: A slotted electrically conductive structure attachable to a substrate and configured to enhance penetration of an incidental radio wave through the substrate is disclosed. The structure allows a substantial portion of the incidental radio wave to penetrate from a first region to a second region through the substrate. The slotted electrically conductive structure comprises a metallic base layer of transparent metal or metal oxide; and one or more patterned slots provided on the metallic base layer. Each of the patterned slots comprises a plurality of feature elements covering an entire area of the patterned slot. The structure reduces thermal energy loss through the substrate and the plurality of feature elements is configured to allow the incidental radio wave to pass through the slotted electrically conductive structure. A multilayer structure comprising the slotted electrically conductive structure and a film structure having randomly distributed irregularly shaped protrusions or pits is also provided.

  • Patent number: 10361488
    Abstract: A dielectric material antenna is disclosed. The antenna includes a first material layer made up of a first material with a low dielectric constant. A surface pattern containing pits is carved out of the first material layer. The pits carved out are then filled up with a second material layer made up of a second material that has a high dielectric constant than the first material layer to form a first antenna layer. A wave launcher is provided near to the first antenna layer with a ground provided at its bottom. The wave launcher helps to couple the energy generated from an energy source to the first antenna layer in order to radiate and receive signals.

  • Patent number: 10249944
    Abstract: Disclosed are a system, apparatus, and method for improving performance of antennas in electronic devices. The disclosed system, apparatus, and method uses a transparent dielectric substrate as an antenna. The transparent dielectric substrate may receive energy from a wave launcher and printed circuit board. To work as an antenna, the whole structure may include at least one wave launcher located between the dielectric transparent substrate and a printed circuit board. Also, the structure may include a ground at the bottom of solid dielectric transparent substrate with a separation space. The space should not be less than wavelength 1/10 of fundamental resonant frequency.

  • Patent number: 10141635
    Abstract: Disclosed are a system, apparatus, and method for modifying a dipole antenna to comprise unequal arm lengths for matching the condition of two different dielectric materials such as air and human body. The modified dipole antenna is built in a cylindrical pipe shape dipole that has a hollow center to let wires pass through it and has little to no effect in antenna performance The antenna can be bent in different shape to fit in any wireless product of any shape or size. The antenna is designed to provide a stable radiation at one side and partial radiation at front side even with human body intervention. Further the antenna can be combined with another similar antenna via a power splitter/divider to form a full 360 degree radiation pattern even in presence of a human body in proximity.
