Antenna in Figure 1. 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 (solid gray line), 20 GHz (dashed black line). (a) Ports 1 and 2 are fed, exciting a field along the direction. (b) Ports 3 and 4 are fed, exciting a field along the direction.
