3G, 4G/LTE antennae are for the smallest PCBs
Two antennae from Antenova, the Integra and Inversa chip antennae are designed specifically to perform in 3G and 4G diversity applications with very small PCBs.
At just 3.3mm high, the antennae are compact for use in slimline devices that will be unobtrusive in use. The antennae 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 antennae are designed to work singly or in pairs for multiple input multiple output (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 antennae 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 a choice of combinations and options for placement while leaving space for other components on the board. The ‘keep-out’ area around the antennae is minimal, allowing them to be placed close to other components.
Integra and Inversa operate at different frequencies. Integra covers 791 to 960, 1710 to 2170, 2300 to 2400 and 2500 to 2600MHz, for European markets. Inversa covers 698 to 798, 824 to 960, 1710 to 2170, 2300 to 2400 and 2500 to 2690MHz for global markets.
The Integra and Inversa antennae are suitable for small tracking devices, onboard diagnostics (OBDs), 4G Mi-Fi routers, medical equipment, tablets, MIMO systems, Femtocell and Pico stations and remote monitoring.
Antenova provides RF design support and help with antenna integration for customers who require these services. There are samples and evaluation boards available.
