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.
