Antenna in Figure 2. Gain in polar form on the principal elevation plane ° of the single element at different frequencies in the operational bandwidth 5–25 GHz: 5 GHz (solid black line), 10 GHz (gray line), 20 GHz (dashed black line). (a) Ports 1 and 2 feed the upper element, exciting a field along the direction. (b) Ports 3 and 4 feed the lower element, exciting a field along the direction.
