Abstract

A high-temperature-resistant adjustable-frequency flexible antenna and a manufacturing method thereof. The high-temperature-resistant adjustable-frequency flexible antenna uses a flexible mica sheet as a flexible base layer, and a dielectrically adjustable ceramic film is arranged between the metal layer and the flexible mica sheet. Adjusting electrodes are arranged on the side of the flexible mica sheet away from the dielectrically adjustable ceramic film, so that the high temperature-resistant adjustable frequency flexible antenna can also adjust the operating frequency of the antenna while being able to withstand higher temperatures.

Description

technical field [0001] The invention relates to the field of flexible antenna manufacturing, in particular to a high-temperature-resistant and frequency-adjustable flexible antenna and a manufacturing method thereof. Background technique [0002] Traditional flexible antennas use polymer materials such as PI film, PET film, LCP film, etc. as the substrate, which are metallized on the surface and then patterned to form a flexible antenna. However, since polymer materials cannot withstand high temperatures, such as temperatures >500°C, traditional flexible antennas cannot be used at high temperatures. [0003] Among inorganic dielectric materials, high-temperature resistant materials mainly include glass, ceramics, etc., but ceramic materials cannot be directly used as flexible substrates because they cannot be flexible. Poor water quality makes it difficult to form a metallized layer with a high-strength bond on the surface. [0004] If the antenna is composed of a metal...
