Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, a kind of monopole paster antenna that there is band to fall into characteristic, including earth plate 1, medium substrate
2nd, feeding network 3 and radiation patch 4, medium substrate 2 is done by conventional F4B-2 (polytetrafluoroethylene (PTFE)) plate material in the present embodiment
Into relative dielectric constant 2.65, loss tangent value 0.0009, thickness 1.0mm, the shape of antenna is as shown in figure 1, antenna
Mode is presented using side, input impedance is 50 Ω.
Antenna in the present embodiment is to be produced on the medium that specification is 38mm × 32mm × 1.0mm by engraving method
On substrate 2, earth plate 1 etches is etched with feeding network 3 and radiation patch in the side of medium substrate 2, the opposite side of medium substrate 2
4, feeding network 3 is made up of microstrip line, and the present embodiment is fed using 50 Ω microstrip lines, earth plate 1 be rectangular configuration and with
Radiation patch 4 is wide, and " day " font fluting 5 is etched with radiation patch 4, and the bottom and upper segment of " day " font fluting 5 is symmetrical
Be provided with opening 6, radiation patch is made up of copper product.
Further, 1.9mm × 0.75mm rectangular channel is provided with the present embodiment in earth plate 1.
As Fig. 3-1 and Fig. 3-2 show specific size of the inventive antenna after optimization design, parameter such as following table：
By simulation analysis, it is known that beamwidth of antenna 2.0-5.0GHz, produce band in 2.8-3.2GHz frequency ranges and fall into characteristic, remove
This frequency range, antenna return loss in effective bandwidth are less than -10dB, voltage standing wave ratio VSWR<2.Produced in 2.8-3.2GHz frequency ranges
Raw band falls into characteristic, improves the practicality of the antenna.
When " day " font fluting 5 is can be seen that not open in Fig. 4-1, antenna only has good radiation near 3.6GHz
Characteristic, it is more than -10dB in 2.4GHz return losses, and without trap section.
Fallen into it can be seen from Fig. 4-2 except band in the effective bandwidth of frequency range, antenna echo between 2.0-5.0GHz damages
Consumption has been even up to -32, -36dB near 2.4GHz, 3.8GHz frequency, has reached good impedance below -10dB
Match somebody with somebody.And the trap frequency with 2.8-3.2GHz.
Result of study shows：Return loss of the antenna in 2.0-5.0GHz (except 2.8-3.2GHz frequency ranges) frequency range is small
In -10dB, and there is fabulous radiance in 2.4 and 3.8GHz.
The present invention is not limited to embodiments described above.The description to embodiment is intended to describe and said above
Bright technical scheme, above-mentioned embodiment is only schematical, is not restricted.This is not being departed from
In the case of invention objective and scope of the claimed protection, one of ordinary skill in the art may be used also under the enlightenment of the present invention
The specific conversion of many forms is made, these are belonged within protection scope of the present invention.
