  author={Vlasis Barousis and Constantinos B. Papadias},
  journal={IEEE Wireless Communications Letters},
Single-fed compact arrays known as electronically steerable parasitic antenna radiators (ESPARs) have recently emerged as a new paradigm for spatial multiplexing that requires only a single radio-frequency (RF) chain and a few easy-to-implement analog tunable loads. Besides the remarkable hardware savings, the ESPAR capabilities are still limited as it is not possible to find appropriate loadings that multiplex any signaling format over the air. Indeed, commonly the loading values are obtained… CONTINUE READING
