Abstract : This paper describes a 2 x 12 element linear array that is electronically scanned with 4-bit diode phase shifters. The antenna is cantilever mounted at one end to a trunnion assembly with the array axis oblique to the horizontal roll axis. In operation the fan-shaped beam generated by the liner array provides 280 degree azimuth scan envelope as station mounted in an aircraft. This antenna design is based on a modular design concept for optimum array performance and reliability at minimum cost. The radiating elements consist of printed circuit dipoles with an integrated microstrip balun and feed assembly. The dipole feeds are excited from miniature coaxial lines which, in turn, are routed from the ground plane to the PIN diode phase shifters.
