Calterah Delivers IWPC Keynote Speech to Introduce the Technology and Emerging Applications of Antenna in Package (AiP)
In a global webinar held by International Wireless Industry Consortium (IWPC) at 11:00 am EST on February 23, Calterah delivered a keynote speech, “AiP Devices Enable Emerging Applications for the Automotive Market”.
Worldwide, over 300 people from about 150 enterprises and institutions including well-known auto OEMs, top Tier-1 auto parts suppliers such as Aptiv, Bosch, and Continental, and companies in the upstream IC supply chain registered and attended the webinar to gain insights on AiP and discuss with Calterah the technology and its applications and development in emerging auto fields.
In their keynote speech, Dr. Dian Wang, Calterah’s Director of EM and Manufacturing Technology introduced the advantages of AiP technology and its development in Calterah, and Product Marketing Manager Zheng Wang shed light on the challenges to existing auto radar solutions and how AiP devices enable emerging applications for the auto market.
According to Dr. Wang, mmWave radar modules enabled by AiP ICs, compared to traditional ones, are more competitive, with higher integration level, smaller size, greater consistency and accuracy in antenna manufacturing, no external connection or radiation loss, less module-level design efforts and lower cost.
In terms of antenna performances, Calterah allows high redundancy for impedance bandwidth and gain in its AiP antenna design. For example, a radar module enabled by a Calterah 4T4R AiP mmWave IC can provide a 45 m detection range for targets of 10 m2 RCS within a 90° FOV and support 4D detection under ultra-short-range radar (USRR) mode. And under short-range radar (SRR) mode, such a module can reach 80 m in detection range for targets of the same RCS within a 90° FOV and offer analog TX beamforming in the vertical direction by utilizing internal phase shifters.
As for the advantages of AiP in auto radar applications, Zheng elaborated on two emerging applications, autonomous parking assistance (APA) and child presence detection (CPD).
Traditional ultrasonic radar solutions applied in the APA scenario have several weaknesses, including short detection range, long measurement time, limited elevation detection, and high susceptibility to the environment. Comparatively, AiP mmWave radar is a better APA solution, because it is capable of long-distance detection with high range resolution and a wide elevation FOV, and free space detection through dense point clouds.
As requirements for vehicle safety tighten, CPD becomes more widely applied and its market also expands rapidly. However, existing mmWave sensors are faced with multiple challenges, including difficult installation due to their large sizes, high power consumption, poor heat dissipation, and high cost. These problems can be handled well with AiP mmWave devices, which satisfy the market requirements for smaller, lower-power and more cost-efficient radar. At the end of the speech, Zheng also demoed the in-cabin radar application implemented by Calterah Rhine-Mini product family.
At the well-attended and highly-interactive webinar, attendees raised quite a few questions regarding AiP and its applications, which were answered enthusiastically and promptly by Calterah.
While the automotive industry is moving towards connected, autonomous, shared and electric (CASE) mobility, auto mmWave radar sensors are gradually becoming standard auto equipment. Calterah’s AiP mmWave ICs are able to satisfy the requirements of USRR, SRR, and in-cabin detection for automobiles, and moreover, with advantages in multiple aspects, they can enable emerging auto radar applications and help reinforce the trend of intelligent vehicles.

Since its establishment in 1998, IWPC (International Wireless Industry Consortium) has focused on discussion of wireless technologies, with members covering all links of the wireless industry supply chain, including Original System Specifiers (OSSs), which are carriers, government agencies and automakers, Original Equipment Manufacturers (OEMs), and suppliers. Through IWPC activities like technical seminars and workshops, OSSs are able to learn timely about the OEMs’ developments and their suppliers’ upcoming technologies directly from the source; OEMs in an open and interactive environment can efficiently learn of the requirements of their customers and their suppliers’ developments, which can be taken into account on their product development roadmaps; suppliers can be informed about the needs of their customers and their “customers’ customers”. IWPC aims at facilitating the supply chain to obtain timely, unbiased, objective and ongoing visibility to the needs of the wireless industry and customers, and delivering insight into vital technologies, market and ecosystem evolution. |
