Abstract
A film transmission line includes a dielectric layer including at least one of a liquid crystal polymer (LCP) structure or a cyclo olefin polymer (COP) structure, and an electrode line on the dielectric layer. A signal loss level (S21) defined of the film transmission line is −1.5 dB or more at a frequency in a range from 20 GHz to 30 GHz. The film transmission line may be applied to a high frequency thin film antenna and an image display device.
Claims18
A film transmission line, comprising:
- a dielectric layer including at least one of a liquid crystal polymer (LCP) structure or a cyclo olefin polymer (COP) structure;
- and
- an electrode line on the dielectric layer,
- wherein a signal loss level (S21) defined as Equation 1 of the film transmission line is −1.5 dB or more at a frequency in a range from 20 GHz to 30 GHz:
- S21 (dB)=10×Log(Output power/Input power). [Equation 1]
