Latest Patents

Tamagawa holds a patent for an "Antenna apparatus including frequency separator having wide band." This invention features an antenna that incorporates a frequency separator composed of multiple lattice structures with a periodic conductive pattern. Each lattice structure is designed to exhibit an inherent resonance frequency and an inductance-capacitance effect at frequencies below this frequency. The periodic conductive patterns are carefully selected to ensure that each lattice structure has a similar inherent resonance frequency. When arranged at specific intervals, these lattice structures demonstrate interactive resonance at frequencies below their inherent resonance frequencies. Additionally, each lattice shows comparable inductance and capacitance concerning obliquely incident electromagnetic waves in both TE and TM modes.
