A part except the feeding point and the offset point is formed so as to have a vertiginous shape.

Description

폴디드 모노폴 인테나 {Folded Monopole Intenna}Folded Monopole Intenna

본 발명은 인테나에 관한 것으로, 더 상세하게는 L값을 형성하도록 일방으로 진행된 피딩포인트와 피딩포인트와 인접한 위치에서 나란히 위치되어 C값을 형성하는 상쇄포인트를 가짐으로써 임피던스값을 금속자체 저항수준으로 줄여 무선신호의 송수신 품질을 획기적으로 향상시킨 폴디드모노폴인테나에 관한 것이다.The present invention relates to an intenna, and more particularly, an impedance value is set to a metal self-resistance level by having a feeding point that has been progressed in one direction to form an L value and an offset point which is located side by side at a position adjacent to the feeding point to form a C value. The present invention relates to a folded monopole antenna, which dramatically improves the transmission and reception quality of a wireless signal.

일반적으로, 인테나(Intenna)란 무선기기의 외부에 장착되는 안테나(Antenna)와 달리 무선기기의 내부에 장착되어 무선기기의 전체 부피를 감소시켜 슬림화시킨 장치를 말한다.In general, intenna refers to a device that is slimmed by reducing the overall volume of a wireless device by being mounted inside the wireless device, unlike an antenna mounted to the outside of the wireless device.

그러나, 종래의 인테나는 핸드폰과 같이 슬림화를 지향하는 무선기기에 탑재되는 용도로 개발된 것이 거의 드물고, 특히 CDMA주파수방식 혹은 PCS주파수방식에서 사용하도록 개발된 것이 전무한 실정이어서 축소지향적인 핸드폰 개발경향의 걸림돌로 인식되어왔다.However, the conventional intenna is rarely developed for use in a wireless device aiming at slimming, such as a mobile phone, and in particular, it is rarely developed for use in the CDMA frequency method or the PCS frequency method. It has been recognized as a stumbling block.

본 발명은 상술한 문제점을 해소하기 위한 것으로, 장착하고자 하는 핸드폰본체의 내부에 구비되어, L값을 형성하도록 일방으로 진행된 피딩포인트와 피딩포인트와 인접한 위치에서 나란히 위치되어 C값을 형성하는 상쇄포인트를 가짐으로써 임피던스값을 금속자체 저항수준으로 줄여 무선신호의 송수신 품질을 획기적으로 향상시킨 폴디드모노폴인테나를 제공하는것이다.The present invention is to solve the above-described problems, provided in the interior of the mobile phone body to be mounted, the offset point to be positioned side by side at a position adjacent to the feeding point and the feeding point to form an L value to form a C value By providing a reduced monopole antenna, the impedance value is reduced to the resistance level of the metal itself, which greatly improves the transmission and reception quality of the radio signal.
