For wireless connectivity market requirement such as WiFi, Internet of Things (IoT) and 5G connectivity application. Those applications will use antenna to transmission the signal to ourside, for 5G mobile communication is the latest generation of communication protocol. The operating frequency band of 5G mobile communication is 28 to 77 GHz in the mmWave band. It uses higher frequency radio waves than 4G LTE cellular networks to achieve higher data transmission rates, due to high frequency that will sufer more challenge for package solutions. The advanced SiP could integrate difference solutions such as antenna design into SiP module and to get small form factor and high electrical performance for good electromagnetic interference (EMI) protection. The EMI is very critical for IC circles which can damage electronic devices and equipment. To meet the high frequency of electrical performancents, the partition EMI shielding has provide the signal isolation between different function blocks such as digital, analog and RF antenna devices in SiP module. In this paper, a test vehicle is designed to evaluate the shielding effectiveness (SE) by vector network analyzer (VNA). The different partition EMI shielding method and study will proceed and measuret under mmWave frequency of 22GHz to 40GHz. Difference material as compartment technology for EMI shield on difference area. We will select difference material for shielding perofmrance comparison and use simulation program was used to evaluate the effectiveness of EMI shielding performance. The TV was designed with mmWave antenna to do mmeasurement and comparison on shielding effectiveness result. Finally, this paper will demonstrate the advanced SiP with alternative low cost EMI shielding solutions for future 5G Connectivity devices application.
