ISM band is relatively conventional in implanted operating frequency of antenna, compared to MICS and WMTS, its using bandwidth, There is higher radio channel capacity, therefore 2.45GHz and 5.8GHz ISM band is used for biotelemetry by many countries.For example Xu. Li-Jie et al. is delivered《Dual-Band Implantable Antenna With Open-End Slots on Ground》The antenna of plane inverse-F structure is used in article, double frequency implanted antenna is devised, but antenna horizontal size is larger, is 19mm×19.4mm×1.27mm;Li Ming nine et al. was in 2017《Electronic component and material》On deliver《A kind of novel three-frequency The design of section implanted antenna》Middle use multilayer planar inverted f structure realizes multifrequency, but up to three layers of the number of plies, both increased thickness or Improve difficulty of processing.Therefore designing a kind of miniaturized multifrequency implanted antenna simple in construction has more real meaning.
The content of the invention
The present invention relates to a kind of small sized double frequency implanted medical flexible antenna, simple in construction, size is smaller, it is easy to process. Fed by coaxial feeder, using loading grounding probe and open and realize two-frequency operation by the way of rectangular channel.Medium substrate and Coating then use dielectric constant for 4 polyimide flex material so that antenna realize miniaturization.
The present invention is adopted the following technical scheme that:
A kind of small sized double frequency implanted medical flexible antenna of the present invention includes radiation patch, rectangular channel, grounding probe, coaxial feed Line, ground plane, medium substrate and coating, it is characterized in that:Described radiation patch is generally square, wherein an edge Center open a rectangular channel, and respectively opened a symmetrical rectangular channel at two adjacent edges.Short circuit is visited The tie point of pin is close to the left hand edge on radiation patch surface, and the distributing point of coaxial feeder is located at the middle lower section on radiation patch surface. Described radiation patch is parallel with ground plane, and radiation patch is connected by grounding probe with ground plane.While coaxial feeder Also radiation patch and ground plane are connected.Described medium substrate is filled between radiation patch and earth plate, and coating position In the top of radiation patch.Medium substrate and coating use dielectric constant for 4 polyimide flex material.
The present invention compared with prior art, with following remarkable advantage:
1st, it is simple in construction:The present invention is simple in construction, and size is smaller, it is easy to process;
2nd, frequency range is adjustable:The present invention can adjust antenna and exist by adjusting the position of grounding probe or adjusting the length and width of each groove Resonance under different frequency range.
