Abstract
본 발명은 위성방송 수신용 평면안테나에 관한 것으로서, 특히 급전선 직상단에 커플링슬롯을 적층시켜 급전선에서 발생하는 불요방사를 차단할 수 있으며 또한, 이중공진효과를 얻어서 안테나의 동작주파수 대역이 넓어지고 이득특성이 좋아진 위성방송 수신용 평면안테나에 관한 것이다.The present invention relates to a planar antenna for receiving satellite broadcasting, and in particular, by coupling coupling slots directly above the feeder line, to prevent unwanted radiation generated from the feeder line, and to obtain a double resonance effect, the operating frequency band of the antenna is widened and gain The present invention relates to a planar antenna for receiving satellite broadcasting with improved characteristics.
현재 사용중인 위성방송 주파수는 11.7∼12.2㎓로서 약 500㎓의 주파수 대역을 가진다.The satellite broadcasting frequencies currently in use are 11.7-12.2 kHz and have a frequency band of about 500 kHz.
이와같은 위성방송의 주파수를 수신하기 위해서 파라볼라 안테나와평면 안테나가 사용되는데, 상기 평면안테나는 포토에칭 방식을 사용하므로 대량생산을 할 수 있으며 가볍고 크기가 작으므로 설치 공간의 제한을 받지 않는 장점을 가지고 있다.The parabolic antenna and the plane antenna are used to receive the frequency of the satellite broadcasting. The planar antenna can be mass-produced due to the photoetching method, and the light and small size do not limit the installation space. have.
그러나, 종래 평면안테나는 급전선이 방사면에 노출되어 있으므로 불요방사가 발생한다. 다시말하면 급전선이 만곡되거나 급전선의 특성임피던스가 변화되는 부분에서 불연속부가 발생되는데, 이러한 부분에서는 수신주파수 대역이 초고주파수이므로 기생 리액턴스가 존재하게되어 결과적으로 안테나의 방사특성이 저하되는 문제점이 있다.However, conventional planar antennas have undesired radiation because the feed line is exposed to the radiation surface. In other words, a discontinuity occurs in a portion where the feed line is curved or the characteristic impedance of the feed line is changed. In this portion, since the reception frequency band is an ultra high frequency, parasitic reactance exists, resulting in a decrease in the radiation characteristic of the antenna.
따라서, 본 발명은 상기 문제점을 해결하기 위해 급전선 직상단에 커플링슬롯을 적층시켜 급전선에서 발생하는 불요복사파를 차단할 수 있으며 또한, 이중공진효과를 얻어서 안테나의 동작주파수 대역이 넓어지고 이득특성이 좋아진 위성방송 수신용 평면안테나이다.Therefore, in order to solve the above problem, the present invention can block unwanted radiation waves generated by the feed line by stacking coupling slots directly above the feed line. In addition, the operating frequency band of the antenna is widened and gain characteristics are obtained by obtaining the double resonance effect. It is a flat antenna for receiving improved satellite broadcasting.
