  • Patent number: 9768512
    Abstract: A radar antenna is disclosed. The disclosed antenna includes: a dielectric substrate; a feed line for feeding RF signals that is formed on an upper portion of the dielectric substrate and has a linear form; a multiple number of radiators that are perpendicularly joined to the feed line and have a bent structure comprising a horizontal portion and a vertical portion; a matching element for adjusting impedance matching that is joined to an end of the feed line; and a ground formed on a lower portion of the dielectric substrate, where a length of the horizontal portion and the vertical portion is set based on a polarization angle of an RF signal that is to be radiated. The disclosed antenna can be manufactured with a simple structure and a compact size.

  • Patent number: 8663786
    Abstract: Disclosed is a polyester film for optical applications, and more specifically to a polyester film having refractive index of 1.6 to 1.7 and a film having refractive index of 1.4 to 1.6 on both surfaces of the polyester film, wherein a thickness of each coating layer is 0.03 to 0.1 ?m and total light transmittance of the entire film is 93% or more. The polyester film according to the embodiment has total light transmittance higher than the polyester film without the coating layer and is more suitable to use the polyester film for optical applications due to the excellent adhesive strength between the polyester film and layer for the post-processing working.
