Abstract
본 발명은 위성 방송 수신용 안테나로서, 전계가 시간에 따라 시계 또는 반시계 방향으로 회전하며 진행하는 원편파 수신용 마이크로 스트립 안테나에 관한 것으로서, 특히 접지도체와 직선 편파 방사소자, 유전체로 구성된 마이크로 스트립 안테나의 방사 소자 상부에 방사소자와 일정한 각도를 이루면서 기울어진 스트립 도체를 형성하여 고이득, 광대역의 수신 특성을 갖도록 한 원편파 수신용 마이크로스트립 안테나에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an antenna for receiving satellite broadcasts, and more particularly, to a circularly polarized reception microstrip antenna in which an electric field rotates clockwise or counterclockwise with time. The present invention relates to a microstrip antenna for circularly polarized wave reception, which has a high gain and wideband reception characteristic by forming an inclined strip conductor at an angle with the radiating element on the radiating element.
종래의 원편파 수신용 마이크로 스트립 안테나의 경우는 2점 급전 방식의 경우 많은 불연속부를 포함하는 복잡한 급전회로를 갖게 되므로 이들 불연속부에 의한 손실이 안테나의 효율을 저하시키게되며, 1점 급전 방식의 경우에는 축비 대역폭이 좁아지는 문제점을 갖고 있다.In the case of the conventional circular polarization receiving microstrip antenna, since the two-point feeding method has a complicated feeding circuit including many discontinuities, the loss caused by these discontinuities decreases the efficiency of the antenna. Has a problem of narrowing the axial ratio bandwidth.
본 발명은 접지도체(10)와 직선 편파 방사소자(11), 상기 접지 도체(10)와 방사소자(11)를 분리시키는 유전체(12)로 구성된 직선 편파용 마이크로 스트립 안테나의 방사 소자(11) 상단에 마이크로스트립 안테나의 편파 방향과 일정한 각도를 유지하는 한개 이상의 스트립 도체(14)와, 이 스트립 도체(14)를 방사 소자(11)와이격시키는 유전체(15)와, 상기 방사 소자(11)와 동일평면상에서 방사 소자(11)에 전자기 에너지를 공급하는 급전선(13)으로 구성된 원편파 수신용 안테나이며, 직선 편파 안테나의 상단에 한개 이상의 평행한 스트립 다이플을 직선 편파 방향과 소정각도를 이루도록 위치시켜 2점 급전 방식의 복잡한 급전 회로 구성을 단순화시키고, 안테나의 효율을 향상시키며, 광대역의 축비 대역폭을 갖는 원편파 수신용 마이크로 스트립 안테나이다.The present invention relates to a radiation element 11 of a linearly polarized microstrip antenna composed of a ground conductor 10 and a linearly polarized radiating element 11, and a dielectric 12 separating the ground conductor 10 and the radiating element 11. At least one strip conductor 14 having a constant angle with the polarization direction of the microstrip antenna at the top, a dielectric 15 separating the strip conductor 14 from the radiating element 11, and the radiating element 11 Is a circular polarization receiving antenna composed of a feed line 13 for supplying electromagnetic energy to the radiating element 11 on the same plane as that of the linear polarization antenna so that one or more parallel strip dimples have a predetermined angle with the linear polarization direction. It is a microstrip antenna for circularly polarized reception by simplifying the complex feeding circuit configuration of the two-point feeding method, improving the efficiency of the antenna, and having a wide bandwidth axial bandwidth.
