Antenova has revealed its latest antenna, Atta (part number SRFI079), for LTE and smart wireless deployments in the 410 MHz and 450 MHz bands.

The antenna comes in a flexible printed circuit (FPC) form and measures 101,0 x 20,0 x 0,15 mm. It is supplied with an I-PEX mating connector for direct integration to a circuit board and a self-adhesive pad to fix it easily in position. It is therefore easy to integrate into a design.

The LTE 450 spectrum is relatively new, with 65 deployments in North America, South America, Europe, Africa and Asia. This is expected to grow as spectrum is allocated in more regions. LTE 450 MHz is used by private network providers in the utilities, public safety and transport sectors. They use it for M2M traffic, smart grids, smart cities, EV charging and rural broadband networks. Europe leads the roll-out with utilities using LTE 450 MHz for critical comms and automated meter reading infrastructure connecting remote areas.

The 450 MHz band compares favourably to 900 MHz for these applications, because at 900 MHz four times as many base stations are needed to cover the same geographical area. The Atta antenna is ideal to provide connectivity for devices on these networks, in particular meters and rugged smartphones and handheld mobile devices using Cat. 4 modules.
