This research presents the effects of an air‐stacked configuration on the novel reconfigurable quadratic antenna. The proposed antenna is made feasible by using a feeding line, PIN diodes, and an aperture coupled feeding structure with quadratic slots shape and varied levels of air‐stacked sequence: 0, 5, 10, 15, and 20 mm. Instead of a quadratic slot, it is proven through simulations and measurements...
