Design of L-band 2×16 phased array antenna

An L-band 2×16 phased array antenna with printed dipole and integrated balun using multi-layering technique has been proposed. The design satisfies some targeted specification such as having a gain of 20 dB and a steering coverage of 90° at the center frequency 1.28 GHz. A sixteen-element linear antenna array is designed and fabricated. Simulation and experimental results of active reflection at port 1, 9 and 16, including gain performance at boresight, and side lobe losses (SLL) levels are presented.
