Embodiment Construction

[0012] The present invention will be further described below in conjunction with drawings and embodiments.

[0013] The technical solution adopted in the present invention is: the antipodal Vivaldi antenna fed by the side of the microstrip is composed of an antipodal radiating patch, a microstrip feeder and a dielectric substrate, wherein the antipodal radiating patch, the microstrip feeder, the delay Both wires and loading resistors are on the same dielectric substrate. The two antipodal radiating patches are respectively located on both sides of the dielectric substrate, and only a small part of the two patches overlap across the dielectric substrate; the two opposite edges of the antipodal radiating patches are opened to form a trumpet-shaped opening. The openings at the ends of the two antipodal radiation patches are the largest, which is the radiation end of the antenna; the end section in the direction opposite to the radiation end, where the edges of the two antipodal r...

Abstract

The invention discloses a micro-strip side feeding anti-pode Vivaldi antenna, relating to an antenna, in particular to a small-size plane antenna. The micro-strip side feed anti-pode Vivaldi antenna consists of anti-pode radiation patches (1), a micro-strip feeder line (2) and a dielectric substrate (3), wherein the two anti-pode radiation patches (1) are positioned on two surfaces of the dielectric substrate (3); opposite edges (4) of the two radiation patches (1) are opened to form a horn-shaped opening; the biggest part of a tail end opening of the radiation patches (1) is an antenna radiation tail end (5), and the other direction of the opening is an antenna transmission section (6); and one end of the micro-strip feeder line (2) is connected with the antenna transmission section (6) from a side edge, and the other end of the micro-strip feeder line (2) is an antenna feed end (9). According to the micro-strip side feed anti-pode Vivaldi antenna disclosed by the invention, the space occupied by a antenna feeding part is saved, so that the size of the antenna is reduced.

Description

technical field [0001] The patent of the present invention relates to a broadband antenna, especially a microstrip side-fed antipodal Vivaldi antenna, which belongs to the field of antenna manufacturing. Background technique [0002] As a planar antenna, the antipodal Vivaldi antenna has the advantages of wide operating frequency, high gain, linear polarization, and easy fabrication, and is widely used. Usually, the antipodal Vivaldi antenna with direct microstrip feeding is composed of three parts: the transition section from the microstrip line to the flat line, the transmission section of the flat line, and the antipodal Vivaldi patch radiation section, which are directly connected in the same direction. The known problems Yes: The microstrip-to-slab line transition section of the antipodal Vivaldi antenna alone occupies a portion of the antenna space. Contents of the invention [0003] Technical problem: The purpose of this invention is to propose a microstrip side-fe...
