Abstract

The invention provides a magnetic monopole endfire antenna array which has the advantages of low profile, wide frequency band and good directivity. The magnetic monopole endfire antenna array comprises an antenna unit, a microstrip transmission line, a microstrip feed line, a dielectric plate and a floor plate. The antenna unit, the microstrip transmission line, the microstrip feed line and the floor plate are printed and processed on the dielectric plate. The antenna unit comprises two pairs of magnetic monopole units which are symmetrically placed on both sides of the microstrip feed line to form two pairs of symmetrical array sources. Each magnetic monopole unit is connected with the microstrip feed line through the microstrip transmission line. The excitation source of the antenna array is radio frequency port excitation. Rectangular slits are symmetrically arranged on both sides of the floor plate. The antenna is flat, has the polarization characteristic of being perpendicular to the plane of the antenna, and has low application height. The aesthetics and the concealment of the antenna are improved. The magnetic monopole endfire antenna array has the advantages of wide frequency band and good directivity.

Description

technical field [0001] The present invention relates to the field of antennas, in particular to a magnetic monopole end-fire antenna array. Background technique [0002] Existing end-fire antenna arrays achieve polarization characteristics parallel to the plane where the antenna is located. If vertical polarization is to be provided, the antenna needs to be perpendicular to the floor, which occupies a large antenna height and seriously affects the aesthetics and concealment of the antenna. Contents of the invention [0003] The present invention provides a magnetic monopole end-fire antenna array to overcome at least one defect (deficiency) described in the above-mentioned prior art. Wide frequency bandwidth and good directivity. Most importantly, the antenna can realize the polarization characteristic perpendicular to the plane where the antenna is located. When the antenna is to provide vertical polarization characteristics, the antenna is in a flat state and has a ver...
