Patent attributes
Provided are a microstrip stack patch antenna using multilayered metallic disk array and a planar array antenna using the same. The microstrip stack patch antenna of the present research concentrates beam patterns and acquires a high gain characteristic by finitely depositing metallic disks in a bore-sight on a conventional microstrip stack patch radiator. The microstrip stack patch antenna includes: a microstrip stack patch directly connected to the feed line; and a mask conductor layer for improving side lobe and gain characteristics, the mask conductor being formed on the microstrip stack patch.
