Latest Patents

One of his latest patents is the "Series-fed E-shaped patch antenna array with co-polarized parasitic patches." This invention features a series-fed E-shaped patch antenna array that incorporates co-polarized parasitic patches to enhance aperture efficiency. The design includes microstrip parasitic patches placed between multiple microstrip E-shaped patch antennas. The co-polarization of the parasitic patches with the E-shaped antennas ensures that the current flows with the same polarity, leading to improved gain flatness and aperture efficiency due to offset resonance frequency.

Another significant patent is the "Beamformer and beamforming method." This invention outlines a beamformer that consists of several dividers, which divide an input signal into multiple paths. It includes an input switch that selects one of the dividers for the input signal, a phase shifter that adjusts the phases of the output signals, and an output switch that transmits these signals to an antenna. This innovative approach enhances the efficiency of signal processing in communication systems.
