The experimental setup of this configuration is shown above. The antenna is designed over a ground of 80 x 80 mm, with a gain of -16dBi. The tuned parasite measuring 48 x 53 mm is then placed above the feed antenna. Other configuration of parasite used are shown below.

Parasite configuration: A - First parasite A1 = Tuned at 48 x 53 (mm); or A2 = 0.5l at 60 x 60 (mm); B - dielectric layer (FR4, thickness 0.508mm) on first parasite; C - Parasite 43.5 x 53 (mm) with U-Slot printed
