Latest Patents

One of his latest patents is focused on a very small aperture terminal for satellite communication with direct conversion and electronic polarization orientation control. This invention describes techniques for direct conversion and dynamic polarization control in a very small aperture terminal (VSAT) outdoor unit (ODU). The ODU includes a direct up-converter and/or a direct down-converter for converting in a single stage between a baseband frequency and a satellite radiofrequency band, such as the Ka band. Additionally, the ODU features a polarization amplifier that integrates high-power amplification with circular polarization orientation control. For instance, the direct up-converter converts a baseband signal to a low-power satellite-RF transmit signal, while the polarization amplifier enhances this signal to an uplink signal with high gain and selected circular polarization. The ODU can also include an integrated embedded computer and modem.

Another notable patent involves a microstrip-to-waveguide transition that includes a substrate integrated waveguide with a 90-degree bend section. This invention features a substrate with a metal layer, a ground layer, and a dielectric layer. The substrate incorporates a microstrip line impedance transformer and a substrate integrated waveguide that is electromagnetically coupled to the microstrip line impedance transformer. The waveguide is arranged perpendicularly to the substrate and is coupled at the 90-degree bend section, ensuring that the microstrip-to-waveguide transition is free of a back-short at this critical location.
