WIDEBAND HIGH-GAIN APERTURE COUPLED ANTENNA FOR KU BAND PHASED-ARRAY SYSTEMS

摘要

Aperture coupled microstrip antenna is presented for Ku band phased-array applications. We show that radial open circuit terminated microstrip feed and hourglass aperture shape provide better coupling, high gain, wide bandwidth and small in-band gain variation. Eight-element antenna array with fixed beam tilt is formed and measured to validate simulations.
