Abstract
The invention belongs to the ultra wide band antenna technology in the field of airborne communication and particularly relates to a small side-feed antipodal Vivaldi antenna with resistor loading. The antenna is a microstrip antenna with a simple structure and is formed by the order stacking of an upper layer metal layer, a medium base plate, and a lower layer metal layer. According to the antenna, on the basis of a traditional antipodal Vivaldi antenna, a feeder is bent to a side, the size of the antenna is reduced greatly, and the miniaturization degree is raised. The width of the feeder is changed in a step way, and thus the antenna maintains good input impedance matching in a wider bandwidth. The directivity is improved by using the modes of resistor loading and a parasitic patch. A loading metal with a special shape is used, and thus a high gain is maintained while the directivity is improved.
