摘要
Vivaldi antenna has been widely used in the microwave imaging system due to its wide frequency range and low cross-polarization character. The directivity and transfer efficiency of the antenna in the system is of great importance to the imaging quality. The Vivaldi antenna is commonly connected to the coaxial line with an SMA connector. However, the SMA connector forms a coplanar waveguide struct...
