433-MHz band antenna offers high gain and simple integration

October 17, 2016 // By Graham Prophet
Antenova (Hatfield, UK), maker antennas and RF antenna modules for M2M and the Internet of Things, has added Inca (part no SRFI028), to its flexiiANT FPC range. This antenna is for small devices in the 433MHz ISM band.

The antenna measures 101.0 x 20.0 x 0.15 mm, and weighs just 0.5g, 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. It 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. Images show radiation pattern and return loss.


This is a flexible antenna, which gives product designers a number of options. It can be folded or placed flat and can be placed within the housing of relatively small devices. It comes with an I-PEX connector in a choice of three cable lengths; 100 mm, 150 mm or 200 mm, and has a peel-back self-adhesive backing to fix it in place. This means that the antenna can easily be placed in a design, in the desired position, and antennas can be retro-fitted to earlier designs. Inca is supplied in packs of 100.
