SMT automotive antennas address global frequencies
Low profile SMT automotive antennas from AVX/Ethertronics that provide best-in-class RF performance and give global coverage are now available from TTI, Inc.

The antennas support different worldwide frequency bands and ensure superior performance, yet occupy minimal PCB real estate. These automotive antennas provide broadband coverage across 4G/LTE, 3G, GPS, WiFi, V2X or BT networks, with turning capabilities to deliver optimized performance.

The Universal Broadband Embedded LTE/LPWA antenna (Part Number P822601) from AVX/Ethertronics utilises Isolated Magnetic Dipole™ (IMD) technology, which provides superior RF field containment and less interference or reaction with surrounding components, important in the electronically-busy automotive environment. The devices resist detuning and maintain a reliable radio link regardless of usage position. Peak gain over different frequencies are 2.6 dBi over 689 to 960 MHz; 4.4 dBi from 1710 to 2200 MHz; and  3.4 dBi over 2500 to 2700 MHz. The devices have a very small PCB footprint of only 49.6- x 8.0- x 3.2-mm.

The AVX/Ethertronics Wi-Fi/BT/Zigbee ceramic chip antenna (Part Number 1001312) also offers the advantages of IMD technology, enabling design engineers to provide the key requirements of high functionality and superior performance in smaller, thinner designs. Measuring only 2.00- x 1.20- x 0.5-mm it operates over the 2400 to 2485 MHz frequency with peak gain of 1.88 dBi.

AVX/Ethertronics provides a wide range of SMT stamped metal antennas for V2X applications. Antenna PN 1002289 provides exceptional characteristics, such as vertical polarization, ideal to improve performance in Vehicle-to-Infrastructure communications.

Designed to be mechanically robust to withstand the rigours of automotive applications, the devices are TS certified and supplied on tape and reel for automated high-volume manufacturing.

In addition, Ethertronics offers a custom design and testing services using its in-house automotive anechoic chamber, located in Antibes (France).
