Embodiment Construction

[0015] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0016] see Figure 1~Figure 3 , introduces the structural composition of the broadband planar printed dipole antenna of the present invention.

[0017] The overall structure of the antenna is rectangular, and it is equipped with: exponential tapered line feed microstrip line (1), dielectric plate (2), two large dipole arms (3a, 3b), two small dipole arms (4a, 4b) and connecting wire (5). Its innovative structure is mainly: the antenna adopts a double-layer printed circuit structure on the front and back sides of the dielectric board (2) in the middle, that is, two pairs of dipoles (3a, 3b), (4a, 4b) and exponential type The tapered feed microstrip line (1) is printed on the front and back sides of the dielectric plate (2): one arm of the large dipole (3a) and on...

Abstract

A broadband planar printed dipole antenna is provided with two large dipole arms (3a and 3b), two small dipole arms (4a and 4b), exponential type gradient line feed microstrip lines (1), connecting lines (5) for connecting the small dipole arms with the feed microstrip lines, and a medium plate (2). The innovation of the antenna structure is to adopt a two-layer printed circuit structure of front and back surfaces of the medium plate: two pairs of large dipole arms (3a and 3b) and small dipole arms (4a and 4b) and the exponential type gradient line feed microstrip lines (1) are printed on the front and the back surfaces of the medium plate (2), so that the wide frequency band matching property and a stable directional diagram are realized; when the standing-wave ratio is less than 2, the band width can achieve 70%, and the directional diagram in the working frequency section is stable. The antenna has the characteristics of small size, light weight, facilitation of integration in various planar devices and simple feed system. As a result, the antenna has the advantages of low production cost, planar structure, wide working frequency band and excellent promotion and application prospect.

Description

technical field [0001] The invention relates to a broadband planar printed dipole antenna, to be precise, to a double-sided printed dipole antenna that can be used for wireless communication, and belongs to the technical field of communication antennas. Background technique [0002] With the rapid development of communication technology, communication systems with many advantages such as low complexity, low cost and wide operating frequency have been developed rapidly and widely used. Because printed dipole antennas have the advantages of small size, light weight, simple structure, and easy mass production, they are used in various communication systems. However, the printed dipole antenna in the prior art has the disadvantages of narrow bandwidth or complicated structural design. For example, the antenna in the 2010 document "Broadband Printed Dipole Antenna" (Chinese Journal of Science, Technology and Engineering, Issue 32, 2010) is a planar printed structure, but its wor...
