Latest Patents
Johnny Chang holds a patent for his invention titled "Construction for Portable Disk Antenna." This invention presents an improved design that includes a disk antenna body, an outer member, an inner member, and a base. The outer member is capable of rotating 360 degrees about a first axis relative to the base, while the inner member is rotably fitted into the outer member. The disk antenna body is connected to the inner member, allowing for rotation within an appropriate angular range about a second axis that is perpendicular to the first axis.
This invention is further characterized by the inclusion of an azimuth calibrating device and an elevation calibrating device. The azimuth calibrating device features an azimuth calibration scale for calibrating the azimuth deviation of the disk antenna body before use, based on compass indications. The elevation calibrating device has an elevation scale for calibrating the elevation deviation according to a level instrument. This design allows users to easily calibrate the azimuth and elevation of the disk antenna body, enabling them to receive expected signals from target artificial satellites effectively.
