A Miniaturized Directional Radiation Printed Antenna

Abstract

The invention discloses a miniaturized directed radiation printed antenna. The lower end of a double-folded reverse-L-shaped conductive trace is connected with a feed and conductive trace, a parasitic radiation unit is arranged in the space over the double-folded reverse-L-shaped conductive trace, and a metal floor is arranged on the back face of the feed and conductive trace. According to the double-folded reverse-L-shaped conductive trace, a metal wire with the length equal to three fourths of a working wavelength is repeatedly bent to form a space electromagnetic field excitation structure provided with two sections of long conductors mutually in parallel. By the adoption of the double-folded reverse-L-shaped space excitation structure, the ideal directed radiation characteristic can be obtained, the parasitic radiation unit is added, so that radiation gains of the antenna in the forward direction are increased, a space mutual-coupling principle is utilized, an antenna closely-spaced technology is adopted, so that space is compressed and the size of the antenna is reduced, and a planar antenna printing technology is adopted, so that a radiation body and the ground are located in planes which are mutually in parallel, equipment space is fully utilized, and integration of the antenna and a circuit board is facilitated.

Description

technical field [0001] The invention belongs to the technical field of electronic communication, in particular to a miniaturized directional radiation printed antenna. Background technique [0002] With the in-depth research and development of wireless communication technology, the performance of communication systems has been continuously improved, and the refined design of antennas has begun to be concerned and valued by researchers to meet the various needs of new application features and performance improvements. For current and future mobile terminal equipment, the development trend is that the volume will become smaller and smaller, and the appearance will become more and more beautiful, while the performance must be maintained or even improved, which puts strict and even harsh requirements on the antenna design. In traditional antenna design, based on the basic antenna prototype, reducing the size of the antenna will be at the expense of other performances of the ante...
