Abstract

The invention provides a boroadband high gain probe and patch tangent laminated microstrip antenna. The antenna comprises a floor, a bottom dielectric layer, a probe, a main vibration patch, a middle dielectric layer, a parasitic patch and a top dielectric covering layer, wherein the three dielectric layers are sequentially overlaid; the floor is positioned below the bottom dielectric layer; the parasitic patch is positioned on the upper surface of the middle dielectric layer; the main vibration patch is positioned on the upper surface of the bottom dielectric layer; the probe is tangent with the main vibration patch to form a feeding structure; the top end of the probe and the main vibration patch are located in the same plane; the circular surface at the top end of the probe is tangent with the long side of the main vibration patch; a distance from a central shaft of the probe to a symmetry axis of the long side of the main vibration patch is equal to that from the central shaft of the feeding probe to a symmetry axis of the short side of the main vibration patch; the main vibration patch and the parasitic patch are in parallel; and symmetry axes of the main vibration patch and the parasitic patch are superposed. The antenna fully meets requirements of millimetric waveband broadband high gain wireless communication, and has the advantages of wide band, high gain, novel feeding mode, simple feeding structure, simple overall structure and the like.

Description

technical field [0001] The invention relates to a laminated microstrip antenna for wireless communication, in particular to a laminated microstrip antenna for broadband high-gain wireless communication in the millimeter wave band. Background technique [0002] Due to the development of radio communication equipment and electronic information equipment towards multi-function, miniaturization, ultra-wideband, frequency upshift, and friendly coordination with the surrounding environment, this makes broadband, miniaturization, high-gain, and millimeter-wave antennas become domestic and foreign One of the hot topics of research.
