We propose a general computational method for guiding the design of an electronically steerable parasitic array radiator (ESPAR) antenna. The radiation field of the 2-element unit cell is calculated to ascertain the port characteristics of the parasitic element, followed by the retrieval of reactive load values as the beam steers. So, DC bias and diode operating parameters have been considered thoroughly. A 9-element ESPAR antenna is proposed to verify the method, with the observed congruence between calculated and measured results validating the method and highlighting its value for designing ESPAR antennas.

Abstract
We propose a general computational method for guiding the design of an electronically steerable parasitic array radiator (ESPAR) antenna. The radiation field of the 2-element unit cell is calculated to ascertain the port characteristics of the parasitic element, followed by the retrieval of reactive load values as the beam steers. So, DC bias and diode operating parameters have been considered thoroughly. A 9-element ESPAR antenna is proposed to verify the method, with the observed congruence between calculated and measured results validating the method and highlighting its value for designing ESPAR antennas.File in questo prodotto:
