Antenna in Package (AiP)
Antenna on Package (AoP)

Amkor is the first OSAT to deliver High Volume Manufacturing (HVM) of products using AiP/AoP technology

Amkor’s cutting-edge AiP and AoP technology has already been deployed and offers fully-integrated5GNR millimeter wave (mmWave) and sub-6 GHz RF modules for smartphones and other mobile devices. These mmWave antenna modules deliver capabilities across several spectrum bands, in a very compact footprint that is well suited for integration in mobile devices.

To date, mmWave signals had not previously been used for mobile wireless communications due to many technical and implementation challenges, that impact nearly every facet of device engineering, including materials, form-factor, industrial design, thermal performance and regulatory requirements for radiated power. Successful implementation of these types of antenna solutions, spanning both mmWave and sub-6 spectrum bands for 5G, will transform the mobile industry and consumer experience.

Why AiP/AoP? What are the Benefits to Smartphones?

AiP/AoP improves 5G signal integrity and overcomes the challenges below, using small footprint-phased antenna array design and minimizing the space required to support mmWave inside 5G devices.

Technical Challenges Addressed by AiP/AoP

• Propagation:High mmWave frequencies experience higher path loss and attenuation, so signals don’t travel very far
• Range:mmWave signals are easily blocked by objects
• 尺寸：mmWave typically requires an array of antenna elements to help overcome these issues, thereby increasing the footprint inside a device
