Abstract

The invention discloses a microstrip patch loading periodic structure three-frequency antenna, and the antennacomprises a dielectric plate (1), a metal radiator (2), a metal floor (3), a DSPSL staggered periodic leaky wave structure (4) and a feed connector (5), wherein the metal radiation patch (2) and the metal floor (3) are respectively connected to the upper surface and the lower surface of the dielectric plate (1), and the DSPSL staggered periodic leaky wave structure (4) is embedded in the middle of the interior of the dielectric plate (1); the metal radiator (2) and the metal floor (3)are of planar structures and cling to the dielectric plate (1), and the feed connector (5) penetrates through the dielectric plate (1) and is connected with the metal floor (3). By designing the microstrip patch loaded staggered periodic structure three-frequency antenna, the antenna can obtain double-frequency or three-frequency characteristics by adjusting the DSPSL periodic leaky wave structure.

Description

technical field [0001] The present invention relates to the field of radio, and more specifically, relates to a tri-frequency antenna with a microstrip patch loaded with an interleaved periodic structure. Background technique [0002] The traditional microstrip patch antenna has the advantages of simple structure and easy fabrication, but the traditional communication frequency band can no longer meet the demand. The development of multi-frequency bands solves the problems of narrow frequency bands and frequency band interference in communication. Multi-frequency antennas can enable antennas to work in multiple frequency bands at the same time without interfering with each other. The existing multi-frequency antennas are large in size, poor in directivity, The problem of the small gain is still to be solved. Contents of the invention [0003] The purpose of the present invention is to solve the defect of low complex structure and low performance in the prior art, and to d...
