High-performing 3G,4G/LTE antennas for the smallest PCBs

PCBs

Antenova, a manufacturer of antennas and RF antenna modules, is now shipping its two newest antennas: Integra and Inversa. These new chip antennas are designed to perform in 3G and 4G diversity applications with very small PCBs.

At just 3.3mm high, the antennas are ultra-compact, so they can be used in slim-line devices that will be unobtrusive in use.

The antennas perform efficiently with a small ground plane, and can even be used on PCBs as small as 65mm. Where the PCB is smaller than 75mm, Antenova provides an additional active tuning circuit to overcome bandwidth reductions.

The antennas are designed to work singly or in pairs for MIMO and diversity systems. They have beam steering which gives good 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.

Integra and Inversa 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 is built for global markets.

These antennas are suitable for small remote monitoring, tracking devices, OBDs, 4G Mi-Fi routers, medical equipment, tablets, MIMO systems, as well as Femtocell and Pico stations.
