Latest Patents

One of his latest patents is the "Horizontal-plane null frequency scanning antenna." This invention features a first sector patch and a second sector patch loaded on a dielectric substrate with any dielectric constant. The circumferences of these patches are connected to the substrate via vertical shorting walls. Notches, a coaxial feeding probe, and a shorting pin are incorporated into the first sector patch, allowing for the excitation, disturbance, and aggregation of the first three radiation patterns. This design generates radiation null points that can be scanned with frequency changes on a horizontal plane. The addition of the second sector patch enables a single-direction null frequency scanning function on the horizontal plane.

Another significant patent is the "Asymmetric massive MIMO channel estimation method based on co-prime array." This method provides a downlink channel estimation technique based on a co-prime array in an asymmetric massive MIMO architecture. It establishes an uplink and downlink system model and observes the frequency domain direction deviation caused by broadband signals. The method allows for uplink receiving to estimate the uplink channel and recover channel parameters such as the number of paths, angle of arrival, and path gain. Ultimately, it reconstructs the downlink channel based on these recovered parameters, addressing the challenge of using the uplink channel for downlink pre-coding.
