High Performance Antenna-in-Package with Test Socket for Millimeter-Wave System

This paper discusses the losses of transition from Millimeter-Wave Antenna in package (mmWave AiP) with test socket. This study provides AiP designers to easily evaluate and optimize the electrical performance of AiP. The proposed 2×2 broadband dual-polarized antenna array designed on the 10 (4+2+4) multi-layer organic substrates with size of 13×13×0.87 mm 3 , The proposed AiP with test socket has better than 10 dB return loss in 24.5-29.5 GHz range, with 5 GHz bandwidth and provides a high-gain (above~ 11 dBi) radiation pattern for 5G mmWave beamforming application.
