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 chipand the conductor area, and is provided with a plurality of grid structures having shapes arranged at intervals in a staggered manner.The artificial magnetic conductor is configured such that the sizeof a pattern shape adjacent to the conductor via hole among the plurality of pattern shapes is smaller than the size of the remaining pattern shapes.

Description

[0001] This application is a divisional application of a patent application with an application date of August 10, 2016, an application number of 201610651737.9, and a patent application entitled "Array Antenna Using Artificial Magnetic Conductor". technical field [0002] The present invention can be applied to an electronic device using a millimeter wave (mmW) frequency band, can use an artificial magnetic conductor to improve signal interference, and is beneficial to miniaturized array antennas. Background technique [0003] In recent years, the functions of electronic devices such as portable terminals have gradually become diversified. Accordingly, in order to equip electronic devices with various functions, more and more components and circuits need to be built in. Accordingly, due to the limited space of electronic devices, Miniaturization of built-in components and circuits is required. [0004] In addition, in an electronic device performing wireless communication, ...
