Description

1요소로 구성된 지그재그형 마이크로 스트립 패치 안테나 {Zigzag-shape Microstrip Patch Antenna comprising one patch}Zigzag-shape Microstrip Patch Antenna comprising one patch}

본 발명은 1요소로 구성된 지그재그형 마이크로 스트립 패치 안테나에 관한 것으로서, 특히 개인통신서비스(PCS: Personal Communication Services)와 무선가입자망(WLL: Wireless Local Loop) 단말기에 내장되는 1요소의 지그재그형 마이크로 스트립 패치 안테나에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a zigzag microstrip patch antenna consisting of one element, in particular a zigzag microstrip of one element embedded in a Personal Communication Services (PCS) and a Wireless Local Loop (WLL) terminal. It relates to a patch antenna.

현재, 가장 많이 사용되고 있는 단말기 안테나는 수축되었을 때 헬리컬 안테나로 동작하고, 확장되었을 때 헬리컬 안테나와 모노폴 안테나가 결합에 의해 동작하고 있으며, 또 휴대용 단말기 본체의 하우징을 접지로 이용하고 있다. 도 4a 및 도 4b에 도시한 바와 같이, 헬리컬 안테나의 일예를 들면 섀시(25)와 그리고 안테나와 통신장비와의 전기적 접속을 마련하는 급전점(22) 및 무선신호를 송수신하는 회로(23)를 포함하고 있다. 또한, 섀시(23)의 외부에 고정된 중공의 나선형 안테나(6)와, 이 나선형 안테나(6)를 통해 슬라이드할 수 있는 직립의 방사체(1)의 부분인 안테나 로드(1)를 포함한다.Currently, the most commonly used terminal antenna operates as a helical antenna when it is contracted, and when a helical antenna and a monopole antenna are operated when they are expanded, the housing of the portable terminal main body is used as the ground. As shown in Figs. 4A and 4B, an example of a helical antenna is a chassis 25, a feed point 22 for providing an electrical connection between the antenna and communication equipment, and a circuit 23 for transmitting and receiving radio signals. It is included. It further comprises a hollow spiral antenna 6 fixed to the outside of the chassis 23 and an antenna rod 1 which is part of an upright radiator 1 which can slide through this spiral antenna 6.

또, 나선형 안테나(6)는 1/4파 형식의 것이며, 급전점(22)을 경유하여 회로(23)에 항상 결합되어 있다.The spiral antenna 6 is of the quarter wave type and is always coupled to the circuit 23 via the feed point 22.

그리고, 직립의 방사체(1)는 1/4파 방사체이고, 안테나 장치는 스위칭 장치(2,12,13)가 마련되어 있어, 안테나 로드를 연장하는 때에 이는 급전점(22)을 경유하여 4분의 1파 방사체(1)를 나선형 안테나와 병렬로 회로(23)에 결합하지만, 안테나 로드를 수축하는 때에는 4분의 1파 방사체를 회로(23)와 급전점(22)으로부터 분리한다.The upright radiator 1 is a quarter wave radiator, and the antenna device is provided with switching devices 2, 12, 13, and when the antenna rod is extended, it is divided into four minutes via the feed point 22. The one-wave radiator 1 is coupled to the circuit 23 in parallel with the helical antenna, but when the antenna rod is retracted, the quarter wave radiator is separated from the circuit 23 and the feed point 22.

이러한 구조의 단말기 안테나는 방사패턴이 안테나 전체의 중심부에서 나타나게 되어 전자파에 의해 인체 두부가 영향을 받을 뿐 아니라, 사용자에 의해 안테나의 방사가 방해를 받아 방사효율의 저하를 초래한다.In the terminal antenna of such a structure, the radiation pattern appears in the center of the entire antenna, and not only the human head is affected by the electromagnetic waves, but also the radiation of the antenna is disturbed by the user, resulting in a decrease in radiation efficiency.

또한, 안테나의 크기가 크고 외부에 부착되어 있어서 단말기 소형화에 많은 제한을 준다.In addition, the size of the antenna is large and attached to the outside, which places a lot of restrictions on the miniaturization of the terminal.

본 발명의 목적은 휴대용 통신 단말기에서 발생된 전자파가 인체에 미치는영향을 줄임과 동시에 방사효율이 높은 1요소로 구성된 지그재그형 마이크로 스트립 패치 안테나를 제공하는 데에 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide a zigzag microstrip patch antenna composed of one element having a high radiation efficiency while reducing the effect of electromagnetic waves generated on a portable communication terminal.

또한, 본 발명의 다른 목적은 휴대용 단말기를 소형,경량화할 수 있는 1요소로 구성된 지그재그형 마이크로 스트립 패치 안테나를 제공하는 데에 있다.In addition, another object of the present invention is to provide a zigzag microstrip patch antenna composed of one element capable of miniaturizing and reducing the weight of a portable terminal.
