Latest Patents

One of Tsukamoto's latest patents is the "Low profile polarization diversity planar antenna." This invention is designed to effectively separate horizontal and vertical polarization. The antenna combines a notch antenna and a patch antenna in a low-profile structure. The notch antenna consists of a ground plate, a feed plate, and a radiator plate, which are stacked in a spaced relation. The radiator plate is shorted to the ground plate at its center and features at least two radial notches. The feed plate carries feeder probes located adjacent to each notch for feeding the notch antenna. The patch antenna is stacked above the radiator plate and is grounded at one portion, with a feed point spaced from the grounded portion. This design minimizes mutual coupling, allowing for effective separation of polarizations.

Another notable patent is the "Planar antenna having polarizer for converting linear polarized waves." This invention features a multilayered arrangement of a grounding conductor plate, a power supplying circuit plate, and a radiating circuit plate. The radiating elements are a series of apertures electromagnetically coupled to power supply probes. A polarizer is included on the radiating circuit plate, enabling the conversion of linear polarized waves into circular polarized waves. This design ensures high efficiency and wide-band cross-polarization characteristics.
