The invention discloses an integrated ultra
wide band antenna of a fusion slot line ultra
wide band filter unit. The integrated ultra
wide band antenna of the fusion slot line ultra wide band filter unit is composed of a
branch loading slot line resonant
cell and a hexagonal paster
radiation unit in a cascading mode. The hexagonal paster
radiation unit is composed of a main hexagonal paster
radiation unit and a gradual micro-strip line, wherein the main hexagonal paster radiation unit is composed of a trapezoid and a rectangle; the
branch loading slot line resonant
cell is composed of a U-shaped slot line resonant
cell and three loaded slot line branches, wherein two ends of the U-shaped slot line resonant cell are connected with a stepped impedance cell, the three branches are uniformly distributed in a
resonator, and the end of the middle
branch is connected with a circular slot line paster. Compared with a traditional ultra wide band filter, the integrated ultra
wide band antenna of the fusion slot line ultra wide band filter unit greatly improves the out-of-
band rejection characteristic of the ultra
wide band antenna based on guaranteeing the circuit volume, effectively reduces the reflection and consumption of the antenna in cascading, and enables the whole performance to be improved. The integrated ultra
wide band antenna of the fusion slot line ultra wide band filter unit achieves the
frequency selectivity of the ultra wide band without changing a feeder structure.
