Abstract

The invention discloses a novel heterogeneous substrate liquid crystal phased antenna and a manufacturing method thereof. A liquid crystal box substrate of the liquid crystal phased antenna adopts a heterogeneous substrate, a glass substrate is used on one side of an antenna radiation patch, and a low dielectric constant substrate easy to process is used on one side of a microstrip line, so that the loss in an electromagnetic wave transmission process is reduced. The radiation patch, a phase shifter and the like are plated on the substrate in the modes of PVD, ion beam and the like, meanwhile, alignment marks are grown on the inner sides of the glass substrate and the dielectric substrate in the modes of ion beam, PVD and the like, alignment is carried out from the side of the glass substrate by utilizing the high transparency of the glass substrate, the alignment operation is simpler and more convenient, and the alignment result is more accurate.
