The Demonstration of Flexibility Antenna on a Liquid Crystal Polymer Substrate Using Inkjet-Printed Technology

Project: National Science and Technology CouncilNational Science and Technology Council Academic Grants

Project Details


The use of inkjet printing technology on a liquid crystal polymer (LCP) substrate to produce high-frequency passive components has been taken important. Many reports have presented the related research. The advantages of inkjet printing technology on a LCP substrate is fast process, low cost, environmentally friendly, and can be achieved integrated and package. The liquid crystal polymer substrate is flexibility and low moisture absorption which comply with portable and wearable electronics. The project uses inkjet printing technology on a liquid crystal polymer substrate to produce the Ka-band miniature antenna comprising a balun filter on a LCP Substrate for wireless transmission of the smart clothing without battery application. In the following is our proposed plan for this year project: 1. Antenna design and simulate: using series-fed two-dipole antenna comprising a balun filter to design a wide band and high gain Ka-band antenna with and without director. 2. Antenna on an LCP substrate using inkjet printing technology: Using the inkjet printing process to realized antenna and balun filter on front and back side of the LCP substrate. 3. Antenna measured and analysis: S-parameters and radiation patterns measured inside a far-field anechoic chamber. 4. Antenna reliability test: bending and water absorption test and measurement.
