[0028] Such as figure 1 As shown, the specific preparation method of the patch of the flexible antenna of the present invention comprises the following steps:
[0029] 1) Firstly, process the flexible medium matrix material such as fiber fabric, cut it into a suitable size, and blow off the dust on the surface in a vacuum environment (0.3-0.5 atmospheric pressure), eliminate the electrostatic effect, and reduce the impact of dust on the process and performance the impact;
[0030] 2) fixing the flexible medium matrix material on the printing table;
[0031] 3) Prepare conductive working fluid from various components according to the following formula;
[0032] 4) Place the conductive working liquid in the color frame of the flat screen or rotary screen printing machine, and the automatic control mechanism controls the automatic lifting, automatic shifting and automatic scraping of the color frame;
[0033] 5) Using the "missing printing" process, the conductive working flui...
Embodiment 1
[0050] at 40g / m 2 Cotton plain weave fabric is used as a flexible dielectric matrix material to prepare a flexible antenna patch. The specific preparation method is as follows:
[0051] 1) Cut the above-mentioned cotton plain weave fabric into a suitable size, and blow off the dust on the surface in a vacuum environment of 0.4 atmospheres to eliminate the electrostatic effect and reduce the impact of dust on the process and performance;
[0052] 2) the cotton plain weave fabric after processing is fixed on the printing table;
[0053] 3) Preparation of conductive working fluid:
[0054] ①Conductive components: Weigh 10kg of conductive components; among the conductive components, nano-silver powder 2kg, graphene 0.5kg, nano-zinc oxide 0.5kg, nano-copper oxide 1kg, aluminum oxide 1kg, nano-titanium dioxide 1.5kg, nano-tri 1kg of ferric oxide, 1kg of tin oxide, 1kg of nano aluminum powder and 0.5kg of zinc chloride;
[0055] ②Adhesive components: LA132 water-based adhesive 3kg...
Embodiment 2
[0065] The difference between this embodiment and embodiment 1 is that this embodiment uses 21g / m 2 The wallpaper is used as a flexible medium matrix material. In the method steps, infrared pre-baking or oven pre-baking is used for 30s, the pre-baking temperature is about 100°C, and the airtight baking is 4min, and the baking temperature is about 118°C to prepare the patch of the flexible antenna. Then the flexible antenna is processed.
