Latest Patents
One of his latest inventions is a compact broadband antenna with a constant radiation pattern. This innovative antenna features multiple elements of unequal lengths arranged in a conical shape. The longest element includes a trap at a specific location, allowing for extended coverage across various frequency bands. The design minimizes the horizontal footprint while maintaining a low Voltage Standing Wave Ratio (VSWR) and a uniform beam pattern over a wide frequency range exceeding 1:20. Additionally, the antenna exhibits a constant radiation pattern over a bandwidth of 1:6, with the potential for expansion through the addition of more elements and traps. The elevation and azimuth patterns demonstrate consistent characteristics from 100 MHz to 600 MHz.
Another significant patent is for a GPS receiver with a calibrator. This invention focuses on calibrating a receiver for satellite positioning systems. It generates a series of calibration signals at preset intervals, which correspond to various satellite signals. The receiver processes these signals while accounting for a relative time-delay bias, enhancing the accuracy of differential delay estimates and total electron content (TEC).
