Abstract

A newly proposed 1×8, 18 GHz beam focusing/shaping PAA has been designed, constructed and tested. The true time delay (TTD) approach employs a piezoelectric bending motor to perturb the EM field in the vicinity of the transmission line, thereby generating the required time delay. Several different transmission media have been investigated and tested based on this technology. Array beam focusing capabilities have been experimentally demonstrated with ∼10° 3-dB beam width variation and ∼12 cm focal distance change.
