Small Flexible Antenna for 433 MHz ISM Band

Antenova has added a brand new antenna to their flexiiANT FPC range. The Inca (part no SRFI028) is an antenna that has been developed to be used in small devices that operate in the 433 MHz ISM band. This flexible antenna measures 101 mm x 20 mm x 0.15 mm, and weighs just 0.5 g, with a peak gain of 2.80 dBi. It is suitable for any small electronic device in the 433 MHz band, typically remote monitoring, robot control, smart meters, home automation and medical devices.

Inca can also be used with low power wireless modules, as the 433 MHz band is increasingly being chosen for IoT applications that exploit the longer range that can be achieved with this frequency. Its flexibility gives product designers a number of options, as it can be folded or placed flat.

The antenna is available with an I-PEX connector and a choice of three cable lengths, 100 mm, 150 mm or 200 mm. It has a peel-back self-adhesive backing to fix it in place. Enabling the antenna can easily be placed in to a design, in the desired position. It can also be retro-fitted in to other designs.
