초록

본 논문에서는 이동 무선 통신 기기에 적합하고 다중 대역에서 동작하도록 설계된 칩 슬롯 안테나를 제안하였다. 제안된 안테나는 시스템 회로 기판(30 mm$\times$60 mm$\times$0.8 mm) 위에 칩 안테나(10 mm$\times$20 mm$\times$1.27 mm)를 접속시킨 구조이며, 안테나의 F자 형태의 패턴의 끝단은 비아를 통해 시스템 회로 기판과 연결되어졌다. 따라서 칩 안테나는 시스템 회로 기판의 마이크로스트립 선로로부터 접지면 슬롯 사이의 전이(transition)를 통하여 효과적으로 에너지를 방사한다. 제작된 안테나의 측정 결과 3:1 VSWR 임피던스 대역폭($\leq$-6 dB)은 1.98 GHz(1.61~3.59 GHz)와 0.8 GHz(5.2~6 GHz)로 나타났다. 제안된 안테나는 DCS, PCS, UMTS, WLAN의 주파수 대역을 만족함으로 무선 통신 기기에 적용 가능할 것으로 사료된다.

In this paper, the chip slot antenna which is used for mobile devices and designed for multi-band is proposed. The proposed antenna is comprised of a chip antenna(10 mm$\times$20 mm$\times$1.27 mm) and a system circuit board(30 mm$\times$60 mm$\times$0.8 mm). The chip slot antenna is mounted on the system circuit board and the end of F-type strip line which is patterned on the chip antenna is connected by a via with a ground plane of the system circuit board. So, a chip antenna radiates effectively the energy by transition between a microstrip line of the system circuit board and a open slot structure of the chip antenna. In the results of proposed antenna, impedance bandwidth of 3:1 VSWR(-6 dB return loss) is 1.98 GHz(1.61~3.59 GHz) and 0.8 GHz(5.2~6 GHz). So, it can cover multi-band of DCS, PCS, UMTS, WLAN. The proposed antenna can be applied to mobile devices.
