Abstract
The utility model discloses an enhanced printed dipole antenna. The enhanced printed dipole antenna comprises an antenna (1), and the antenna (1) comprises a printed board (3), a dipole (4) arranged on the right side of the printed board (3), and a feeder line (5) arranged on the backside of the printed board (3) and matching the dipole (4). The dipole (4) comprises a floor (7) and a pair of oscillators (6), and a reflecting plate (2) is arranged at one side of the antenna (1) and is connected with the floor (7). The beneficial effects of the utility model are that: the reflecting plate is arranged at one side of the printed dipole antenna, so that when arriving at the reflecting plate, the electromagnetic wave energy is reflected to the front of the reflecting plate, and accordingly, the electromagnetic wave energy in front of the reflecting plate is promoted substantially; the gain of the antenna can reach 4dBi in the reflection direction, so that the performance of the antenna can be promoted greatly, and the application range of the enhanced printed dipole antenna of the utility model is expanded.
Description
Technical field
The utility model relates to a kind of printed dipole antenna, particularly relates to a kind of enhancement mode printed dipole antenna.
Background technology
Antenna is a kind of important microwave device, and in various receive-transmit systems, requisite element, comprise dipole antenna.Although all use broad-band antenna in measurement at ordinary times, all need to use dipole antenna in the measurement of site attenuation and antenna factor.
Along with people constantly strengthen the integrated requirement of communication quality and communication equipment, as the communication equipment subassembly, antenna also needs higher performance to meet the needs of communication system.Now, a kind of printed dipole antenna has appearred, this antenna is that dipole is printed on the thin-medium substrate, it is lightweight, easily process and provide quite wide bandwidth and advanced purity, the structure of this antenna is namely: take printed board as support, one side arranges dipole, and another side arranges the coupling feeder line.
The most important technical indicator of antenna is the directional diagram of antenna, a gain that important indicator is antenna of reflection antenna pattern, the gain of antenna refers under the condition that input power equates, the ratio of the power density of the signal that actual antennas and desirable radiating element produce in same point place, space, so-called ideal radiation unit is omnidirectional antenna, antenna does not have directivity, to space all directions radiation.The gain of general dipole antenna is 2dBi, and printed dipole antenna just becomes the printed board structure to common dipole antenna, and performance is not improved, and the gain of antenna also only has 2dBi, can't meet the requirement of a lot of systems.
The utility model content
The purpose of this utility model namely is to overcome the deficiency of present technology, and a kind of enhancement mode printed dipole antenna is provided, and solves the gain of existing printed dipole antenna too low, the defect that is difficult to apply in a lot of systems.
The utility model is achieved through the following technical solutions: the enhancement mode printed dipole antenna, comprise antenna, described antenna comprises printed board, is arranged on the dipole in printed board front and is arranged on the feeder line that the printed board back side coordinates with dipole, described dipole comprises floor and a pair of oscillator, one side of described antenna is provided with a reflecting plate, and reflecting plate is connected with floor.
Described reflecting plate is arranged on the positive downside of antenna, and reflecting plate is mutually vertical with printed board.
Be provided with via hole in the position over against feeder line on described reflecting plate.
The plate area of described reflecting plate is greater than the plate area of printed board.
Described reflecting plate is square or circular.
Described reflecting plate adopts electric conducting material to make.
The beneficial effects of the utility model are: the side at printed dipole antenna arranges a reflecting plate, when electromagnetic wave energy arrives reflecting plate, namely be reflected to the place ahead of reflecting plate, the electromagnetic wave energy in reflecting plate the place ahead is promoted greatly like this, this antenna can reach 4dBi in the gain that the party makes progress, greatly promoted this antenna performance, increased range of application of the present utility model.

In figure, 1-antenna, 2-reflecting plate, 3-printed board, 4-dipole, 5-feeder line, 6-oscillator, 7-floor, 8-via hole.
Embodiment
The utility model is described in further detail below in conjunction with embodiment, but structure of the present utility model is not limited only to following examples:
[embodiment]
As shown in Figure 1, Figure 2, Figure 3 shows, the enhancement mode printed dipole antenna, comprise antenna 1, described antenna 1 comprises printed board 3, is arranged on the dipole 4 in printed board 3 fronts and is arranged on the feeder line 5 that printed board 3 back sides coordinate with dipole 4, described dipole 4 comprises floor 7 and a pair of oscillator 6, one side of described antenna 1 is provided with a reflecting plate 2, and reflecting plate 2 is connected with floor 7.
Further, experimental results show that, above-mentioned reflecting plate 2 is arranged on the positive downside of antenna 1, namely near a side of floor 7 and feeder line 5 tip sides, and reflecting plate 2 is mutually vertical with printed board 3, and at this moment the reflecting plate 2 electromagnetic energy gain effects in the place ahead are better, and the plate area of reflecting plate 2 is greater than the plate area of printed board 3, have better reflecting effect, the gain effect of antenna is better.And reflecting plate 2 is connected with floor 7, and reflecting plate 2 is located at a side on floor 7, facilitated both to connect.
Be provided with via hole 8 in the position over against feeder line 5 on said reflection plate 2, because reflecting plate 2 while being arranged on the positive downside of antenna 1, can stop the antenna terminal installation site, the installation that via hole 8 is convenient antenna joints be set.
Further, above-mentioned reflecting plate 2 is square or circular, is also installing and using of convenient whole antenna.
Said reflection plate 2 adopts electric conducting material to make, and as metals such as copper, aluminium, perhaps other have the material of electric conductivity.
setting antenna 1 is omnidirectional antenna for the ideal radiation unit, the radiation of antenna 1 does not have directivity, to space all directions radiation, and the radiation gain of all directions is all 2dBi, during the present embodiment work, the electromagnetic wave that antenna 1 is radiated reflecting plate 2 can be reflected to the upside of antenna 1, the electromagnetic wave energy of antenna 1 upside is exactly the electromagnetic wave energy that the downside of antenna 1 while not establishing reflecting plate 2 adds upside like this, gain is namely two 2dBi, the present embodiment is at upside like this, the namely gain in the place ahead of reflecting plate 2 is 4dBi in fact, greatly promoted the performance of this antenna, increased the range of application of this antenna.
