One of his notable inventions is a vehicle antenna for satellite communication. This invention discloses a design and implementation of an X-band antenna optimized for a moving vehicle to communicate with a stationary orbit satellite. The new antenna design employs unique circuit boards that contain dipole elements, power dividers, pin diode switches, and digital phase shifters. The circuit boards perform together as an array to produce high gain beams. Depending on the antenna performance needs, several antenna boards may be required. The circuit boards' dimensions are all identical, containing round disks of equal diameters. The dipole radiating elements are located near the outer edge of the board and are designed to perform circular type polarization. By increasing the diameter of the board and the number of boards, or a combination of the two, one can achieve any desired beam shape that may be required. The disclosure design approach is unique and flexible; for this reason, an eight circuit board vehicle antenna has been configured. The disclosure antenna body is a cylindrical shaped structure with a diameter of 4.25 inches and a height of 8.50 inches. This design approach is also applicable to frequencies other than X-band. Outstanding characteristics of the disclosure antenna include high performance, a rigid body, and low cost.
Another significant invention by Wong is a high gain variable beam Wi-Fi antenna. This invention discloses a design and application of a variable beam antenna optimized for Wi-Fi applications in data, video, and voice transmission, with an emphasis on medical monitoring. The subject antenna consists of a unique group of dipole radiators that are excited by zigzag feed lines and perform together as an array. This antenna is unique because it can provide various high gain beams by simply applying electrical shorts at the cross points in the feed lines. The shorts can be created mechanically or electronically. The antenna beam coverage can range from 15° to 110° wide in the H plane and maintains a constant beam width of 60° in the E plane. The shorts are applied to reduce the antenna's effective aperture, thereby increasing the beam
