Problems solved by technology

[0005] For example, the application number is 201910805353.1, and the patent name is "A Flexible Wearable Microstrip Patch Antenna Based on PDMS Material". The upper side of the PDMS dielectric substrate is provided with a radiation patch and an impedance matching transmission line, and the ground plate is located on the dielectric. On the underside of the substrate, the radiation patch is directly added on the PDMS substrate. According to the material characteristics of PDMS itself, its adhesion to the metal patch is not high, and it is easy to fall off when placed directly on PDMS, and its durability is low, and its work narrow bandwidth

Abstract

The invention relates to a low-cost embedded wearable antenna, which comprises a radiation patch (3), a strip line (4), a ground plane (5), an upper PDMS dielectric substrate and a lower PDMS dielectric substrate. The antenna adopts a coplanar waveguide feeding mode for feeding, namely the ground plane (5), the radiation patch (3) and the strip line (4) are positioned on the same plane; and the radiation patch, the ground plane and the strip line are embedded into the upper PDMS dielectric substrate and the lower PDMS dielectric substrate to form an embedded structure. The center frequency ofthe antenna is 5.8 GHz, the reflection coefficient at the resonant frequency is-26.20 dB, the working bandwidth is 5.25-10.54 GHz, and the antenna can be used for medical service at the frequency bandof 5.725-5.875 GHz. The low-cost embedded wearable antenna has the characteristics of ultra-wideband characteristic and the like, and is higher in stability, lower in cost and more convenient to process.

Description

technical field [0001] The invention belongs to the technical field of wearable antennas, and in particular relates to a low-cost embedded wearable antenna. The antenna uses polydimethylsiloxane (PDMS) material as a dielectric substrate and has a stable structure, low cost and easy processing. Flexible wearable antenna with ultra-wideband properties. Background technique [0002] In the novel coronavirus outbreak that broke out in 2020, due to the highly contagious nature of the virus, it is necessary to ensure that medical staff and infected persons maintain a certain safe distance, and at the same time be able to monitor the health information of patients in real time. Wireless wearable devices in this case It can play an important role, so the present invention designs a wearable antenna that can work in the medical service frequency band 5.725-5.875GHz. [0003] As wireless communication and the Internet of Things begin to spread to all areas of people's daily life, hug...
