Abstract
본 발명은 마이크로스트립 패치 어레이 안테나(Microstrip patch array antenna)의 회로로서 크기는 작고 이득(GAIN)이 좋은 고이득의 평면 안테나에 대한 회로도이다.The present invention is a circuit diagram of a high gain planar antenna having a small size and good gain (GAIN) as a circuit of a microstrip patch array antenna.
이를 위해 유전율(E)이 낮은 프린트기판을 이용하여 작은 패치 엘리먼트들을 배열 분포시켜 각 패치들이 신호를 수신하고 이들을 스트립라인을 이용해 병합하여 수신이득을 높일수 있다. 본 발명의 안테나는 극초단파(UHF)중 이동통신용으로 사용되는 CELLULAR(800Mhz~990Mhz)용으로 전파를 송수신 할수 있는 안테나이며 크기가 작아 기지국에 설치가 간편할 뿐아니라 환경 친화적인 안테나로서 설치장소의 영향을 받지 않는다. 그리고 빔폭과 이득(GAIN)을 자유롭게 조절할수 있으므로 셀(sell) 서비스 범위를 구축하기가 쉽다.To accomplish this, small patch elements are arranged and distributed using a printed circuit board having a low dielectric constant (E) so that each patch receives signals and merges them using a stripline to increase reception gain. The antenna of the present invention is an antenna that can transmit and receive radio waves for CELLULAR (800Mhz ~ 990Mhz), which is used for mobile communication among ultra-high frequency (UHF), and its size is small, so it is easy to install in the base station and also influences the installation place as an environmentally friendly antenna. Do not receive. And because the beam width and gain (GAIN) can be freely adjusted, it is easy to build a sell service range.

상기한 목적을 이루기 위하여 유전율(E)이 3이하인 유전체 프린트기판을 사용하여 구성한 회로로써 패치 엘리먼트들을 스트립 라인을 이용해 결합회로에 연결시킴으로써 전파를 한곳으로 모아 송수신 감도를 높였다. 본 회로도는 유전율과 기판의 두께를 고려하여 스트립 라인을 구성하여야 하며 패치 엘리먼트는 결정된 주파수의 파장에 의하여 크기와 간격을 조정하여 CELLULAR(800Mhz~990Mhz)용 안테나 외에도 극초단파(SHF)용 안테나도 설계 할 수 있으며 본 발명의 구성은 다음과 같다.In order to achieve the above object, a circuit composed of a dielectric printed circuit board having a dielectric constant (E) of 3 or less is used to connect patch elements to a coupling circuit by using a strip line to collect radio waves in one place to increase transmission and reception sensitivity. This circuit diagram should be composed of strip line considering the dielectric constant and the thickness of the board, and the patch element should be designed for the microwave (SHF) antenna in addition to the antenna for CELLULAR (800Mhz ~ 990Mhz) by adjusting the size and spacing according to the wavelength of the determined frequency. The configuration of the present invention can be as follows.
1. 유전율이 3 이하인 프린트기판을 이용하여 해당 주파수와 유전율에 의해 전파를 수신할 수 있는 패치 엘리먼트를 기판에 설계한다(도1). 여기서 패치의 크기는 주파수와 관련되고 패치의 간격은 안테나의 지향성을 결정하여 전파의 수신 폭을 넓게 할 것인지 좁게 할 것인지를 결정하게 된다.1. Using a printed circuit board having a dielectric constant of 3 or less, a patch element capable of receiving radio waves at a corresponding frequency and dielectric constant is designed on the substrate (Fig. 1). Here, the size of the patch is related to the frequency, and the spacing of the patches determines the directivity of the antenna to determine whether to widen or narrow the reception width of the radio wave.
2. 유전율이 3 이하인 프린트기판을 이용하여 해당 주파수와 유전율에 따라 피드라인 두께를 결정하고 결합회로로 피드라인을 집합 시켜주는 스트립 결합 회로를 설계하여 패치 엘리먼트들로 부터의 신호들을 결합하여 수신 이득을 높였다.(도2)2. Using a printed board with a dielectric constant of 3 or less, design a strip coupling circuit that determines the feedline thickness according to the frequency and dielectric constant and aggregates the feed lines into the coupling circuit, combining the signals from the patch elements to receive the gain. (Fig. 2)
3. 1,2에 의해 설계된 2개의 프린트기판을 겹쳐서 도 3, 도4와 같이 하나의 안테나 모듈을 완성한다. 이렇게 완성된 마이크로 스트립 평면 안테나는 이 자체로서 전파를 송수신할 수 있는 안테나이며 안테나의 정면 방향으로 지향성을 갖는다.3. One antenna module as shown in FIGS. 3 and 4 is completed by overlapping two printed boards designed by 1,2. The completed microstrip planar antenna is itself an antenna capable of transmitting and receiving radio waves and has a directivity toward the front of the antenna.
4. 3에서 완성된 안테나 4개를 도5와 같이 직각으로 배치하면 안테나의 지향성은 360도 전 방향이 되며 4개의 직각 배열된 안테나들의 신호를 한곳으로 결합해 주는 스트립 라인 결합회로 도6를 이용해 결합 시켜 안테나를 완성한다.4. If the four antennas completed in 3 are placed at right angles as shown in Fig. 5, the directivity of the antennas is 360 degrees and the strip line coupling circuit combines the signals of the four right-angled antennas into one place. Combine to complete the antenna.
이와 같이 완성된 안테나는 효율을 나타내는 전압정재파비(VSWR) 1.5 이하를 얻었고 이득(GAIN)은 10db 이상을 얻을수 있으며 아울러 이득(GAIN)은 패치 엘리먼트의 간격을 조정하면 빔 다이어 그램을 자유자재로 변형시킬 수 있어 송수신 면적대비 이득(GAIN)을 높일 수 있다.The antenna thus obtained has a voltage standing wave ratio (VSWR) of 1.5 or less indicating gain, and gain (GAIN) can be obtained more than 10db, and gain (GAIN) can freely transform the beam diagram by adjusting the spacing of the patch elements. It is possible to increase the gain (GAIN) relative to the area of transmission and reception.
본 발명은 이동통신용 CELLULAR용 안테나로서 마이크로 스트립 패치 어레이 안테나 방식을 적용하여 크기는 작아지며 고 이득은 낼수 있는 안테나로서 기존 이동통신용 안테나에비해 가격은 저렴하고 설치는 용이하다. 따라서 전세계적으로 대두되는 기지국 설치장소와 설치비용을 현격히 감소 시킬수 있으며 환경친화적인 기지국을 만드는데 일조할수 있다. 또한 안테나의 빔 다이어그램을 자유자재로 변형시킬수 있어 셀(CELL)단위 운영방식에 가장 적합하다.The present invention is an antenna for a mobile communication CELLULAR antenna by applying a microstrip patch array antenna method, the size is small, high gain can be cheaper than the conventional mobile communication antenna and easy to install. Therefore, it is possible to drastically reduce the installation location and installation cost of the base station that is emerging all over the world, and to help create an environment friendly base station. In addition, the beam diagram of the antenna can be freely modified, which is most suitable for cell unit operation.
