Abstract
A liquid crystal polymer composite film is formed from a resin composite including one or more liquid crystal polymers and one or more fillers. The liquid crystal polymer composite film has a thickness in the range of 10 μm-200 μm and a ratio of the in-plane dielectric permittivity in the machine direction to the transverse direction in the range of 1.0-1.4 over a frequency range of 1 Ghz to 10 Ghz. A metal-clad laminate includes the liquid crystal polymer composite film and a metal clad layer laminated to a major surface of the liquid crystal polymer composite film. The metal-clad laminate may be included as part of an antenna.
Claims18
A liquid crystal polymer composite film formed from a resin composite, the resin composite comprising:
- one or more liquid crystal polymers present in an amount in the range of 40 wt % to 95 wt % based on a total weight of the liquid crystal polymer composite;
- and
- one or more porous fillers comprising zeolite having an average pore diameter of 2 nm or less present in an amount in the range of 5 wt % to 60 wt % based on the total weight of the liquid crystal polymer composite;
- wherein a thickness of the liquid crystal polymer composite film is in the range of 10 μm-200 μm;
- and
- wherein a ratio of an in-plane dielectric permittivity in a machine direction of the liquid crystal polymer composite film to an in-plane dielectric permittivity in a transverse direction of the liquid crystal polymer composite film is in the range of 0.9-1.1 over a frequency range of 1 GHz to 10 GHz.
