KYOCERA AVX, a global leader in advanced electronic components, offers a range of exceptionally compact and high-performance internal, on-board, multiprotocol, 2.4GHz antennas. These antennas are ideal for system-in-package (SiP) applications, which are experiencing rapid growth.
SiP modules are miniature chip carriers that house multiple integrated circuits (ICs) with distinct functionalities.
They often include various silicon and passive components and perform most, if not all, the functions of an electronic system, such as processing, memory, and specialized tasks. Their small size, flexibility, high performance, and simplified assembly enable faster design cycles and improved time-to-market.
Consequently, the growth of 5G mobile and wearable devices, high-performance computing (HPC), artificial intelligence (AI), the Internet of Things (IoT), and autonomous vehicle industries is driving significant growth in the SiP market.
KYOCERA AVX provides a selection of extremely small and lightweight, high-performance, lab- and field-tested, and -proven on-board, multiprotocol, 2.4GHz antennas. These antennas are engineered for easy implementation and optimized for cost-sensitive, space-constrained, mass market applications that utilize SiP modules. All solutions are RoHS-compliant and packaged on tape and reel for automated pick and place assembly.
1001312 Wi-Fi/Bluetooth/Zigbee/Matter Ceramic Antenna: This linearly polarized ceramic antenna boasts high efficiency (62%), a peak gain of 1.88dBi, and superior RF field containment in a compact 2.0 x 1.2 x 0.55mm (L x W x H) SMT package, weighing just 0.003g. It supports the 2,400–2,485MHz band and offers a configuration for 6.0–8.5GHz for ultra-wideband (UWB) applications. Additionally, it’s available in an A-Series automotive version (A1001312).
9005868 2.4GHz Corner Chip Antenna: This linearly polarized chip antenna stands out by supporting Wi-Fi, Bluetooth, Bluetooth Low Energy (BLE), Zigbee, WLAN, ISM, and Matter protocols. Unlike other chip antennas typically designed for placement towards the PCB edge, this antenna is particularly suited for corner placement, making it an ideal solution for applications with small PCBs. It features an omnidirectional radiation pattern, high efficiency (72%), a peak gain of 4.0dBi, and superior RF field containment in one of the smallest, lightest, and lowest profile SMT packages available on the market. This compact package measures just 1.0 x 0.58 x 0.35mm (L x W x H) and weighs only 0.0009g. Moreover, it’s rated for operating temperatures ranging from -55°C to +125°C, demonstrating outstanding reliability and repeatability over temperature compared to traditional ceramic chip antennas due to its tight tolerance. Additionally, it’s available in an A-Series automotive version (A9005868).
The 9001978 Ultra-Small 2.4GHz Chip Antenna is a linearly polarized chip antenna designed to deliver high functionality, versatility, and performance in small and thin designs. It boasts one of the smallest, lightest, and lowest profile SMT packages currently available on the market, measuring just 1.00 x 0.55 x 0.40 (L x W x H) and weighing less than 0.001g. This antenna supports 2,400–2,485MHz band protocols, including Bluetooth, Zigbee, and Matter, as well as configurations for 6.0–8.5GHz for UWB and 2.4/5.0GHz dual-band Wi-Fi applications.
The A-Series automotive Bluetooth, UWB, and dual-band Wi-Fi versions of this antenna are also available and are qualified according to AEC-200 standards. This antenna exhibits high efficiency (65%) and 3.0dBi peak gain in 2,400–2,485MHz applications. It is rated for operating temperatures extending from -55°C to +125°C and provides outstanding reliability and repeatability over temperature compared to traditional ceramic chip antennas due to its tight tolerance.
These antennas are ideal for use in cost-sensitive, space-constrained, mass market applications that utilize SiP modules, such as smart tags, wearables, other consumer electronics, smart home sensors, and healthcare devices. The A-Series versions are particularly well-suited for applications like wireless battery management systems (wBMS) and tire pressure monitoring systems (TPMS).
Each of these antennas is also available with downloadable resources designed to ease the implementation process for engineers, including PCB layouts in Drawing Interchange Format (DXF) files and Ansys HFSS and CST encrypted simulation files.
