We are proud to introduce an innovative dual-band (28/39 GHz) 1×4 antenna array, specifically designed for 5G mobile applications. This design aims to achieve dual-band operation and higher isolation within an ultra-compact size of just 3.8×23mm² in an antenna-in-package (AiP) module. 🔍 Design Highlights Our antenna design utilizes a frequency… Read More

System-in-Package (SiP) module with higher component density and smaller form size was demonstrated through selective structure. The selective EMI shielding at partial molding area for specific substrate circuit exposure through roller-type auto taping / detaping of PI tape was performed. This PI tape was applied on to designed area and… Read More

In this study, we present a 2×2 broadband dual-polarized antenna array on the 10 (4+2+4) multi-layer organic substrates with size of 13 × 13 × 0.87 mm3 and measured by test socket. The antenna structure is a stacking patch antenna with parasitic elements, the most suitable substrate stack-up is selected… Read More

In order to satisfy the requirement of applications at 5G or next-generation communication, the mmWave antenna becomes an important part of systems. In this work, the stacked patch antenna is adopted in the 8-layer packaging with a thickness of 0.92 mm. The double-layer parasitic elements are proposed on the antenna… Read More

5G communication has been widely implemented since year 2020, especially for FR1 sub-6GHz range. Band n77, n78 and n79 are three critical bands in the 5G FR1 because of higher frequency and much wider bandwidth – This also brings new challenge on filter design. In this work, we propose a… Read More
