Latest Patents

Jonas Sandstedt's most recent patents showcase his inventive prowess. One notable patent is a **Microstrip distribution network device for antennas**. This device is designed for microstrip distribution networks and group antennas, effectively suppressing unwanted modes on the distribution network side. By avoiding unwanted coupling between antenna elements, this invention enhances overall performance. The device incorporates a waveguide substructure fashioned as a U-shape from extruded aluminum, connected via two conductive lines to the ground plane. This innovative approach forms a waveguide structure that acts as a high-pass filter, dimensioned to cut off frequencies higher than those used in the microstrip distribution network.

Another significant patent is the **Antenna device**, specifically engineered for dual-polarized microwave antennas with single-polarized patches. This invention aims to reduce cross-polarization and cross-coupling while maintaining the antenna's bandwidth and minimizing grating lobes. Sandstedt's design modifies the traditional rectangular geometry of single-polarized patches to create a narrowing effect towards the ends along the polarization axis. This innovative design results in improved performance through reduced coupling and cross-polarization.
