Abstract EN
Wireless sensors emerged as narrowband, resource-constrained devices to provide monitoring services over a wide life span.
Future applications of sensor networks are multimedia-driven and include sensor mobility.
Thus, sensors must combine small size, large bandwidth, and diversity capabilities.
Compact arrays, offering transmit/receive diversity, suffer from strong mutual coupling (MC), which causes lower antenna efficiency, loss of bandwidth, and signal correlation.
An efficient technique to reduce coupling in compact arrays is described herein: a defect was inserted in the ground plane (GNDP) area between each pair of elements.
The defect disturbed the GNDP currents and offered multidecibel coupling suppression, bandwidth recovery, and reduction of in-band correlation.
Minimal pattern distortion was estimated.
Computational results were supported by measurements.
The bandwidth of unloaded arrays degraded gracefully from 38% to 28% with decreasing interelement distance (0.25λ to 0.10λ).
Defect-loaded arrays exhibited active impedance bandwidths 37–45%, respectively.
Measured coupling was reduced by 15–20 dB.
