Washable flexible wearable dielectric-buried circularly polarized microstrip antenna

Abstract

The invention discloses a washable flexible wearable dielectric-buried circularly polarized microstrip antenna comprising a dielectric substrate, a first dielectric cover layer, a second dielectric cover layer and a conductor patch. The conductor patch includes a ground plane and a radiation patch; the ground plane is arranged between the first dielectric cover layer and the dielectric substrate;and the radiation patch is arranged between the second dielectric cover layer and the dielectric substrate and is connected electrically with a microstrip line. The first dielectric cover layer, the dielectric substrate, and the second dielectric cover layer coat the conductor patch. The antenna has advantages of light weight, good rain and fog interference suppression effect, good anti-multipathreflection performance, small size, low cost, fast processing, good conformal property, good waterproof performance, high safety, good matching degree with an integrated circuit, good anti-corrosion performance, and high washability and the like and is suitable for the UHF RFID and GSM.

Description

technical field [0001] The invention belongs to the field of antenna technology and radio frequency communication technology, and in particular relates to a washable, flexible and wearable medium-buried circularly polarized microstrip antenna. Background technique [0002] At present, with the rapid development of the Internet of Things (IoT), mobile terminals connected to the Internet in various forms have exploded, especially making the body area network (BAN), that is, the body-centered communication network system, have been well developed. The environment stimulates the demand for mobile terminal antennas. Based on the complexity and variability of the application environment, it also puts forward higher requirements for the terminal RF front-end, which has become one of the current research hotspots. The development of traditional antennas is relatively mature, but they cannot be stretched, bent, conformal, and immersed in water, and cannot maintain good duplex communi...

AI Technical Summary

Problems solved by technology

The development of traditional antennas is relatively mature, but they cannot be stretched, bent, conformal, and immersed in water, and cannot maintain good duplex communication capabilities based on these mechanical or environmental requirements, which limits the large-scale application of wearable antennas in body area networks.

Changes such as antenna deformation, water immersion, and corrosion directly affect the performance of the antenna itself. Traditional antennas cannot be conformal, water-immersed, and corroded, so that they cannot fully play their role in the development of body area networks.
