Abstract:
PURPOSE: A waveguide slot array antenna and a planar slot array antenna are provided to improve signal quality of a main beam by suppressing a surface wave radiated from the slot and a sidelobe by a reflection wall. CONSTITUTION: A waveguide slot array antenna(100) includes a waveguide(120) and a plurality of reflection walls(130). One end(140) of the waveguide is inclined to the preset angle. A plurality of slots(110) are formed on an outer surface of the upper wall of the waveguide with a constant interval. A plurality of concave grooves are formed in an inner surface of the lower wall of the waveguide. The plurality of reflection walls are formed in the outer surface of the upper wall of the waveguide. The plurality of reflection walls reduce a sidelobe and a surface wave radiated from the plurality of slots.

Abstract:
A sleeve dipole antenna for wireless communication device is provided to be directly contacted in a circuit board of a wireless communication device without a separate connector by including a feeding unit of a coplanar waveguide type. A dielectric film(250) is a thin film of insulator material, and determines a shape of an antenna. A signal line(260) is formed on the dielectric film. One end of the signal line receives a RF(Radio Frequency) current from a transmitting output circuit of a wireless communication device. The other end of the signal line emits the RF current into a free space. A first ground line(270) and a second ground line(275) are formed on the dielectric film, and are arranged in both sides of the signal line. A third ground line(280) and a fourth ground line(285) are formed on the dielectric film, and are arranged in both sides of the signal line into a longitudinal direction of the first ground line.
Abstract:
본 발명은 해중림 조성부재에 관한 것으로, 보다 구체적으로는 해조류들이 잘 착생할 수 있는 부착기질을 제공하는 해중림 조성부재가 다수 개 결합되어 형성된 부유형 해중림 조성부재 복합체에 관한 것이다. 본 발명의 해중림 조성부재 복합체를 구성하는 해중림 조성부재는 해조류들의 착생력이 매우 우수할 뿐만 아니라, 상기 해중림 조성부재에서 성장하는 해조류가 상기 해중림 조성부재에 뿌리를 용이하게 내리고 튼튼하게 잘 성장하게 되어 해중림 조성시간을 단축할 수 있는 장점이 있다. 또한 다수의 해중림 조성부재가 복합체를 구성하여 해저 바닥이 아니라 바다속 일정 높이에 떠서 존재하는 부유형일 뿐만 아니라, 이동도 가능한 구조이므로 해조류포자가 다수 존재하는 해역에 설치하여 해조류를 착생시킨 후 즉시 또는 일정기간 생장시킨 다음 상기 해중림조성부재복합체를 백화현상이 발생한 해역으로 이동시켜 설치할 수 있으므로 해중림조성에 매우 유리하다.
