Latest Patents

Ka-Hyeon Lee holds a patent for the "Structure of magneto-electric dipole array antenna with inclined bridge structure." This invention proposes a structure of a Magneto-Electric Dipole (MED) array antenna that features an inclined bridge structure. The design aims to achieve a wide impedance bandwidth characteristic by introducing an additional resonance point. By transforming a conventional post shape into an Inclined Bridge-Connected (IBC) MED, the antenna improves gain flatness due to a stable radiation pattern across the operational frequency band. Additionally, the symmetrical structure of the IBC posts enhances resonance in the low-frequency band. The inclusion of a rounded bridge further contributes to this improvement. The design generates magnetic dipoles through currents induced between the IBC posts and the cavity, forming loops. Furthermore, applying an angle difference to the IBC post enhances resonance in both middle and high-frequency bands. Ka-Hyeon Lee has 1 patent to his name.
