Abstract

The invention discloses a novel balance Vivaldi antenna adopting an extra dielectric layer loading technology and a mixed type ripple edge, relates to the field of an antenna, and aims to solve the problem of severe beam deflection of the existing balance broadband microstrip antenna which works in a millimeter wave band. A conductor metal layer is attached between two dielectric substrate layers; two floor metal layers are attached on the two sides of the two dielectric substrate layers respectively; two extra dielectric layers are attached on the two sides of the two floor metal layers respectively; the two dielectric substrate layers are both rectangular structures; arc-shaped nicks are formed in the centers of the rectangles; the conductor metal layer adopts a comb-shaped structure; an M-shaped groove is formed in the comb head of the comb-shaped structure; multiple rectangular grooves are uniformly formed from one side to the comb tail of the M-shaped groove; the comb tail of the comb-shaped structure is connected with a comb handle; the comb heads of the floor metal layers are connected with a strip line structure through a balance-imbalance converter; and a region clamped between the comb head of the conductor metal layer and the comb heads of the floor metal layer coincide with the arc-shaped nicks of the dielectric substrate layers. By virtue of the novel balance Vivaldi antenna, beam stability can be improved.

Description

technical field [0001] The invention relates to a novel balanced Vivaldi antenna adopting an additional dielectric layer loading technology and a hybrid corrugated edge, belonging to the field of antennas. Background technique [0002] The Vivaldi antenna is a widely used ultra-wideband planar antenna. It was first proposed by Gibson. It is a kind of gradient slot antenna. Its main feature is that the gradient slot conforms to the shape of the slot line changing with the exponential function, and has good impedance bandwidth and wide beam. Etc. [0003] The high-frequency impedance bandwidth of the traditional Vivaldi antenna is still limited by the feed structure. Gazit designed the Vivaldi antenna in 1988, converting the two radiating arms of Vivaldi into the form of anti-exposure, and using a gradual balun to transition the parallel double lines to Microstrip line, and using the microstrip line structure to feed, breaks through the limitation of the traditional Vivaldi a...
