Problems solved by technology

[0002] Antennas are an indispensable part of the communication field. The traditional periodic microstrip leaky wave antenna can realize the forward and backward scanning of the main beam of the antenna. However, in order to strictly comply with the repeatability of the physical cycle, the structure of each cycle unit must be consistent. Therefore, the shape and size of

Abstract

The invention discloses a two-dimensional microstrip leaky wave antenna with a shaped unit. The leaky wave antenna comprises an antenna body. The antenna body comprises a dielectric plate, a metal transmission line, a metal ground plate, the shaped unit and a feed joint arranged on one side of the dielectric plate. The shaped unit comprises one or more of a first rectangular unit, a second rectangular unit loaded with a unitary short stud, and a third rectangular unit loaded with a periodic short stud. The first rectangular unit, the second rectangular unit and the third rectangular unit are alternately spliced on both sides of the metal transmission line. The shaped unit and the metal ground plate are oppositely arranged on both sides of the dielectric plate. The center feed pin of the feed joint is connected with the metal transmission line. The outer conductor of the feed joint is connected with the metal ground plate. The leaky wave antenna provided by the invention has the advantages of reasonable design and controllable antenna size, can be applied to a communication system with higher requirements on antenna size and shape, and can further improve antenna gain and expand radiation.
