[Abstract]:In recent years, with the development of mobile communication and wireless physiological sensor technology, Wireless body Area Network (WBAN), a new short-range wireless communication technology, has been paid more and more attention. Ultra-wideband (UWB) technology has become one of the best candidate technologies for wireless body area network (WLAN) because of its high speed and low transmission power. The design of wearable UWB antenna also poses a new challenge to the traditional antenna design theory. Advances in microelectronics technology have led to the development of implantable devices towards miniaturization. In order to reduce the size of the whole device, how to realize the miniaturization of the antenna and improve the performance of the antenna is a problem that must be solved by researchers at present. The main work and results of this paper are as follows: (1) combining with the comfort requirement of wearable antenna, using electromagnetic simulation software HFSS, based on flexible printed circuit board technology, a prototype monopole antenna of flexible ultra-wideband (Ultra WideB3 and UWB) is designed. Then the performance of the prototype monopole antenna in the body-domain network is studied. The radiation of the antenna to the human body is reduced by loading the reflector. Finally, the designed antenna is machined and tested. The experimental results show that, after loading the reflector, The antenna has less backward radiation in the body area network, and its impedance bandwidth covers the entire UWB band in both cases of straight placement and conformal bending with the arm) by introducing a new metal ground structure. Based on the prototype monopole antenna, a bracketed ultra-wideband (UWB) antenna with metal ground structure is designed. The antenna works in the high frequency band of UWB (6-10GHz). Two ultra-wideband notch antennas are designed by loading half-wavelength open-circuit resonator or 1/4 wavelength short-circuit resonator on the prototype monopole antenna. The notch function of UWB antenna is realized and applied to body area network. Simulation and test results show that, The two UWB notch antennas designed in this paper cover the entire UWB band and form notch 4 at the WLAN 5.8 GHz band in both cases of flat placement and conformal bending of the arm, and combine the miniaturization requirements of the implantable antennas. By means of meandering, lamination and grooving, a single frequency implantable antenna applied to implanted medical transmission service, Medical Implant Serversus Micros, and a dual-frequency implantable antenna working in the ISM 2.4 GHz band of mics and industry, science and medicine are designed. Compared with the existing similar research, the implantable antenna designed in this paper can effectively reduce the volume of the antenna under the condition that the gain is equal to that of the existing implantable antenna.
