摘要：
Three novel, super-wideband antipodal slot antennas with different tuning stubs are studied and compared with each other. Smooth, half-circular slot profile is used to improve the antennas' polarization purity and impedance bandwidth, and different tuning stubs are used to finely tune the antennas' radiation performance. As will be reported, low crosspolarizationlevel,stable dipole-like pattern, and flat gain performances can be obtained within an operation bandwidth of 6.3:1 by introducing a smooth antipodal slot structure and a cup-shape tuning patch.
