  • System for near field communication (NFC) and frequency modulation (FM) communication and portable electronic device using the same
    Patent number: 9077388
    Abstract: A system for near field communication (NFC) and frequency modulation (FM) communication includes a NFC microchip, a FM microchip, a control microchip, a switch module. The switch module switches between the NFC matching module and the FM matching module under control of the control microchip. A NFC matching module electronically connected to the antenna modulates working frequency of the NFC microchip to match with an antenna. A FM matching module electronically connected to the antenna modulates working frequency of the FM microchip to match with the antenna.

  • Slot Antenna
    Publication number: 20100271277
    Abstract: A slot antenna includes a dielectric substrate, and an antenna body that is formed on the dielectric substrate. The antenna body defines an open loop antenna slot that has first and second ends, and an open loop perturbation slot that extends inwardly from the open loop antenna slot, and that has first and second ends, each of which is connected to a respective one of the first and second ends of the open loop antenna slot.
