Abstract :
A crossed meander antenna and a crossed staircase antenna are studied for RFID based sensor networks. Both antennas are designed to operate in the unlicensed 915 MHz frequency band. Each antenna occupies a printed circuit board area of 152 by 102 sq. mm. It is demonstrated that the crossed staircase antenna has low mutual coupling (<-30 dB), overall good radiation pattern coverage, and high peak gain (2.1 dBi) suitable for RFID based sensor networks.
