Array antenna adopting artificial magnetic conductor

Abstract

The invention discloses an array antenna adopting an artificial magnetic conductor. According to one embodiment of the invention, the array antenna comprises a dielectric substrate provided with a first layer, a second layer, and a third layer, which are in an overlapped arrangement; a conductor area, which comprises a grounding surface and a feeder, which are disposed on the first layer of the dielectric substrate; a patch antenna, which is disposed on the third layer of the dielectric substrate, and is provided with a plurality of unit antennas having parts connected with the feeder by passing through conductor through holes; and the artificial magnetic conductor, which is disposed on the second layer of the dielectric substrate, and is used to block interferences between the patch chip and the conductor area, and is provided with a plurality of grid structures having shapes arranged at intervals in a staggered manner. By adopting the above mentioned structure, resonance is formed at a preset frequency.
