Printed PCB Antenna Performance of ATWINC15x0-MR210PB

The printed PCB antenna on the ATWINC15x0-MR210PB is a meandered Inverted F Antenna (IFA). The antenna is fed via matching network that is matched for the module installed on a 1.5 mm thick main board (FR4 substrate material). Main board thickness deviation by ±1 mm changes RX/TX performance by ±1 dB maximum, referring to RX/TX performance with a default antenna-matching network and installed on a 1.5 mm thick main board.

Measured peak antenna gain is -0. 3 dBi.
