Latest Patents

One of Chung-Yi Lee's notable patents is the "Balanced Dipole Antenna for Mobile Phones." This invention features a radiator element and a counterpoise, both made from conducting material. The counterpoise is electrically isolated from the ground plane of a printed wire board (PWB) in mobile phones. A matching network, such as a balun, provides balanced current to the dipole antenna, resulting in a symmetric radiation pattern. This design allows for superior performance compared to conventional antennas, enabling users to communicate effectively in all directions, achieving a 360-degree communication capability.

Another significant patent is the "RF Coupler for Wireless Telephone Cradle." This invention involves a cradle that can be mounted in a vehicle or other suitable locations to support a wireless dual-frequency telephone with an antenna. The cradle includes a plastic housing and a ground plane within it. A trough-shaped feed coupler element is electrically connected to matching circuits and an input/output connector. The design includes a first parasitic coupler element aligned with the feed coupler element, which connects to the ground plane and electromagnetically couples signals of a first frequency to and from the antenna. Additionally, a second parasitic element is positioned adjacent to the feed coupler element for coupling signals of a second frequency.
