Design of Millimeter Wave Dual-polarized Wideband Wide-angle Scanning Antenna-in-packaged
The high integration of the antenna-in-packaged(AiP)poses a significant challenge in achieving dual-polarized structure design and wideband wide-angle performance in the integrated environment.Therefore,this paper utilizes low temperature co-fired ceramic(LTCC)technology to implement an orthogonal magnetoelectric(ME)dipole antenna and introduces a bridge method for designing orthogonal arms.This approach enhances the integration level of the antenna element,improves coupling effi-ciency of the dipole antenna,and resolves issues related to high integration arrangement of dual-polarized AiP.Additionally,a new butterfly type parasitic patch is designed to further enhance antenna bandwidth.Ultimately,optimization and processing of the mil-limeter-wave Ka band wideband wide-angle dual-polarized AiP are achieved.The performance of the machined 9×9 dual-polarized array(36.50×36.50×1.25 mm3)is tested against the scanning pattern of an active stationary array.The impedance bandwidth of the array reaches 24.1％(31.4 GHz～40.0 GHz),while the 3 dB beamwidth exceeds±70°,demonstrating excellent wideband wide-angle characteristics suitable for thin wideband wide-angle scanning millimeter-wave phased array systems in an integrated package environment.
