摘      要：To improve the received signal strength(RSS) and signal-to-interference and noise ratio(SINR),electronically steerable parasitic array radiator(ESPAR)array antennas are designed for the ultra-high frequency(UHF) radio frequency identification(RFID) communication systems that can provide very low power consumption in sensor tag edge. Higher gain, appropriate radiation pattern, and most power-efficient array antennas are completely essential in these sensor network *** a result, it is suggested that ESPAR array antennas be used on the RFID reader side to reduce interference, multipath fading, and extend communication range. Additionally, a system architecture for UHF-RFID wireless sensor network(WSN) communication is put forth in order to prevent interference from antenna nulling technology, in which ESPAR array antennas could be capable of generating nulls. The array antennas within the system demonstrate high efficiency, appropriate radiation patterns, and gains(9.63 dBi, 10.2 dBi, and 12 dBi) from one array to other arrays. The nulling technique using the proposed array antennas also provides better SINR values(31.63 dB, 33.2 dB, and 36 dB). Finally, the nulling space matrix is studied in relation to the channel modeling. Therefore, the suggested approach might offer better communications in sensor networking systems.
