3G,4G/LTE Antennas Keep PCBs Compact

Antenova introduces two antennas, the Integra and Inversa, for 3G and 4G diversity applications employing very small PCBs. Measuring 3.3-mm high, the antennas, perform efficiently with a small ground plane and can be used on PCBs as small as 65 mm. Where the PCB is smaller than 75 mm, Antenova provides an additional active tuning circuit to overcome bandwidth reductions.

 

The components are designed to work singly or in pairs for MIMO and diversity systems. They have beam steering which gives reliable isolation and cross correlation and will provide faster downloads in diversity applications. They are made in left and right versions: the Integra antenna, part numbers SR4L049-L / SR4L049-R, and the Inversa antenna part numbers SR4L034-L / SR4L034-R. One or two antennas can be used on a PCB and they can be placed in a left or right corner, on any side of the PCB. This gives designers plenty of combinations and options for placing them in a design while leaving space for other components on the board. The ‘keep-out’ area around the antennas is minimal, allowing them to be placed close to other components.

SENSORS EXPO & CONFERENCE

Sensors 2018 Hits Silicon Valley June 26-28!

Join thousands of engineers this June in San Jose at the sensor industry’s biggest event! With 65+ Technical Sessions, 100+ Leading Speakers, and 300+ Interactive Exhibits, there’s more opportunity than ever to connect with this booming industry and the technologies driving it. See thousands of the newest technologies in action, learn about the latest applications, including AI, Autonomous Vehicles, IoT, and Medical, and develop invaluable partnerships at the only event dedicated to sensors, connectivity, and systems.

 

 Both operate at different frequencies: Integra covers 791-960 MHz, 1710-2170 MHz, 2300-2400 MHz and 2500-2600 MHz, for European markets, while Inversa covers 698-798 MHz, 824-960 MHz, 1710-2170 MHz, 2300-2400 MHz and 2500-2690MHz and for global markets.
