Example Embodiment

[0013] The present invention is further explained below in conjunction with the drawings.

[0014] The PZT / PVDF composite flexible dielectric microstrip antenna as shown in the figure is characterized in that: the microstrip antenna includes a PZT / PVDF composite as a dielectric substrate, and a circular polarization with a frequency of 5.8 GHz is constructed on the dielectric substrate. Microstrip antenna structure and feeding device. PZT / PVDF is made of lead zirconate titanate (Pb(Zr x Ti 1-x )O 3 ) And the polymer material polyvinylidene fluoride (PVDF) in a certain way to form a composite material. Lead zirconate titanate (PZT) is a high dielectric constant ceramic material, which is ground into a powder with a particle size of 1μm~5μm by a ball mill; polyvinylidene fluoride (PVDF) is a flexible low-loss polymer material, using dimethylformamide After the solution is dissolved, it is mixed and stirred with the PZT powder in different formulations, and treated with ultrasonic to...

Abstract

The invention relates to a PZT/PVDF composite material flexible medium microstrip antenna, pertaining to the field of wireless communication technology. The microstrip antenna comprises a PZT/PVDF composite material medium substrate, which is characterized in that the microstrip antenna comprises a medium substrate, and a circular polarization microstrip antenna structure with the frequency of 5.8GHz and a feeder apparatus are constructed on the medium substrate. Because the PZT/PVDF composite material used is a flexible medium with high dielectric constant and low power consumption, the circular polarization microstrip antenna structure with the frequency of 5.8GHz is constructed on the PZT/PVDF composite material, the upper surface is in the shape of copper-coated microstrip antenna, the lower surface is the metal ground, and the microstrip antenna feeds through the edge of coaxial joints. The invention is characterized in small size and flexible installation, particularly being suitable for miniature wireless radio frequency communication system.

Description

technical field [0001] The invention relates to a flexible dielectric microstrip antenna, in particular to a PZT / PVDF composite material flexible dielectric microstrip antenna, which belongs to the technical field of wireless communication. Background technique [0002] Introduction to background technology. In the existing small-scale short-distance directional wireless communication system, the base material of the microstrip antenna is mostly polytetrafluoroethylene, ceramic or composite dielectric material, and the relative dielectric constant of these materials is low (generally less than 10), so the made The size of the antenna is large, which is not conducive to the miniaturization of the system; and the material is hard and cannot be bent, so it is not suitable for installation on similar curved surfaces. The invention uses the PZT / PVDF flexible composite material with high dielectric constant as the medium to design the microstrip antenna, the antenna is small in s...
