Latest Patents

Zhang's latest patents include innovative designs that enhance the performance of antennas. One of his notable inventions is the "Dual-band filtering antenna array using filtering antenna elements for mutual coupling suppression." This invention features a filtering antenna element that comprises a feeding element, a sub-substrate, a sup-substrate, and an air gap between the sub-substrate and the sup-substrate. The design incorporates a stacked patch on the sub-substrate's top surface, along with a driven patch and a ground plane. An asymmetric E-slot is arranged on the driven patch, and a shorting pin is inserted into the sub-substrate to generate radiation nulls in stopbands. This compact dual-band filtering antenna array requires no feeding network and achieves an isolation of 35 dB, making it suitable for potential base station applications.

Another significant patent is the "Low-profile dual-band filtering patch antenna." This invention is designed for use in LTE MIMO systems. It utilizes two embedded U-shaped radiating patches and a multi-stub microstrip feed-line to generate two operating bands and four radiation nulls that can be individually controlled. The design is simple and flexible, resulting in a MIMO antenna that boasts a very low profile, low mutual coupling, and low envelope correlation coefficients (ECCs).
