  • PIFA array
    Patent number: 9799944
    Abstract: A PIFA (Planar Inverted-F Antenna) array antenna has multiple PIFAs. The PIFA array is used to provide different radiation patterns for communication. A signal being emitted by the PIFA array is manipulated. According to the manipulation, the PIFA array may emit the signal with an omni-directional radiation pattern or a directional radiation pattern; the same PIFA array (antenna) is used for both directional communication and omni-directional communication. The PIFA array may be used in mobile computing devices, smart phones, or the like, allowing such devices to transmit directionally and omni-directionally. The signal manipulation may involve splitting the signal into components that feed PIFAs, and before the components reach the PIFAs, changing properties of the components (e.g., phase) relative to each other.
