This study presents a broadband, dual-polarized stacked patch antenna array module developed for mobile Antenna-in-Package (AiP) applications utilizing an asymmetric substrate stack-up. A key design challenge in 5G mmWave AiP systems is achieving wideband operation, dual-polarization, and compact form factor simultaneously-particularly under the spatial constraints of mobile devices. To address this, the proposed antenna incorporates an L-probe feeding, which significantly enhances impedance bandwidth through capa…
