A broad band antenna consisting of half wave strip dipoles the arms of which are printed on opposite sides of a thin substrate is proposed. Four-element array is fabricated. The feed network comprised of power dividers and impedance transformers is designed to improve antenna performance. Antennas have bandwidth greater than 21% for VSWR<1.5 (without reflector) and 20% for VSWR<2 (with reflector)...
