본 발명은 평면형 도파관을 이용한 다이폴 안테나에 관한 것으로, 더욱 상세하게는 인쇄회로기판의 상/하면에 상호 대칭적으로 위치하는 평면형 도파관이 상호 연결된 구조로 적어도 하나의 차단 주파수를 가지는 일체형 평면 도파관과 정합 기능을 가지는 전송선을 통해 급전되어 낮은 복사 손실과 우수한 신호 전송 특성을 가지는, 평면형 도파관을 이용한 다이폴 안테나에 관한 것이다. The present invention, more particularly, to integrated planar waveguide and matching with at least one cut-off frequency of a phase / if to cross-symmetric planar waveguide is an interconnected structure which is located in the printed circuit board in accordance with the dipole antenna with a planar waveguide the power supply through the transmission line and a function with low radiation losses and superior signal transfer characteristics, to a dipole antenna using a planar waveguide.

일반적으로, 통신시스템에서 평면형 안테나와 평면형 도파관을 사용하는 것은 통신 시스템의 가격을 낮추고, 소형/경량화를 추구하기 위함이다. In general, the use of the planar antenna and the planar waveguide in a communication system is to reduce the price of a communication system, seeking the small / light weight. 이때, 평면형 안테나와 평면형 도파관은 PCB(Printed Circuit Board) 또는 LTCC(Low Temperature Co-fired Ceramic) 등의 무기재료 또는 유기재료의 인쇄회로기판을 이용하여 구현될 수 있다. At this time, the planar antenna and the planar waveguide may be implemented using an inorganic material or a printed circuit board of an organic material, such as PCB (Printed Circuit Board) or LTCC (Low Temperature Co-fired Ceramic).

특히, 평면형 안테나 중에서 다이폴(dipole) 안테나는 전방향(omni directional) 복사 특성을 가지기 때문에 통신 시스템용 안테나로서 주로 사용되었다. In particular, in a planar dipole antenna (dipole) antenna is used mainly as an antenna for a communication system due to its radiation characteristics are omnidirectional (omni directional). 그런데, 다이폴 안테나는 평형 기능을 가지는 급전선이 필요하지만, 일반적으로 통신 시스템용 부품은 불평형 회로로 구성되어 있다. However, the dipole antenna requires a power supply line has a ballast function, it generally includes a part for a communication system is composed of an unbalanced circuit.

따라서, 다이폴 안테나에 급전되는 불평형 특성을 가지는 신호를 평형 특성을 가지는 신호로 변환해야 한다. Thus, the need to convert the signal to an unbalanced characteristic is fed to the dipole antenna to the signal having the balanced properties. 이 기능을 하는 것이 발룬(balun)이다. It is balun (balun) for this function. 발룬이 없으면 다이폴 안테나의 동분극(copolarization) 복사 특성 뿐만 아니라, 크로스 분극(cross polarization) 특성이 나빠진다. If the balun not only the same polarization (copolarization) radiation characteristics of the dipole antenna, deteriorates the cross-polarization (cross polarization) characteristics.

특히, 통신 시스템의 성능 향상을 위하여 분극 다이버시티(polarization diversity)와 같은 방법을 이용하는 경우가 많은데, 크로스 분극(cross polarization) 특성이 나쁘면 정상적으로 동작하는 통신 시스템을 구현하기가 어려워진다. In particular, it is difficult to implement a communication system in which a lot, cross polarization (cross polarization) Poor characteristics operate properly when using a method such as polarization diversity (polarization diversity) in order to improve performance of the communication system.

따라서, 복사 손실이 낮고 우수한 신호 전송 특성을 가지는 다이폴 안테나가 절실히 요구되고 있다. Thus, there is an urgent need for a dipole antenna having a superior signal transmission characteristics with low radiation losses.

본 발명은 상기 문제점을 해결하기 위하여 제안된 것으로, 인쇄회로기판의 상/하면에 상호 대칭적으로 위치하는 평면형 도파관이 상호 연결된 구조를 가져 적어도 하나의 차단 주파수를 가지는 일체형 평면 도파관과 정합 기능을 가지는 전송선을 통해 급전되어 낮은 복사 손실과 우수한 신호 전송 특성을 가지는, 평면형 도파관을 이용한 다이폴 안테나를 제공하는데 그 목적이 있다. The present invention has an integrated planar waveguide and matching functions of a planar waveguide with at least one cut-off frequency bring the cross-linked structure which is located to have been proposed to solve the above problem, in a mutually symmetrical to the upper / lower face of the printed circuit board the power supply through the transmission line with low radiation losses and superior signal transfer characteristics, to provide a dipole antenna using a planar waveguide it is an object.
