Latest Patents

One of Jia Sun's latest patents is the "Broadband Aperture Coupled GNSS Microstrip Patch Antenna." This multilayer antenna structure is designed to receive Global Navigation Satellite System (GNSS) and augmentation signals. The antenna features a microstrip patch radiation element at the top layer and a ground plane forming a first interior layer. The ground plane includes at least two coupling apertures and is isolated from the radiation element by a low-loss dielectric. Additionally, the structure incorporates a bottom layer, which is also isolated from the ground plane by another dielectric. The design includes at least two feed lines connected to a hybrid coupler on the bottom layer, along with an active circuit that connects to the hybrid coupler.

Another significant patent is the "Programmable Radio Frequency Predistortion Linearizer and Method Thereof." This invention consists of a radio frequency (RF) predistortion linearizer that includes a transistor and a control circuit, along with input and output matching circuits. The control circuit is electrically linked to a control voltage source, which supplies control voltages through a control node. A resistor and a coupling inductor connect the control circuit to the control node to receive these control voltages. The control voltages adjust two varactors in the control circuit to provide a specific capacitance. This capacitance, combined with an inductance from an inductive block, allows for a controllable resonant frequency based on the center frequency of an RF input signal.
