초록

본 논문에서는 집적회로 구성을 위 한 초광대역(ultra wideband: UWB) coplanar waveguide(CPW) 급전 L자 평면형 모노폴 안테나 구조를 제시한다. 제안된 CPW 급전 초광대역 L자 평면형 모노폴 안테나는 유전체 기판(${\varepsilon}_{r}=3.38,\;@10\;GHz$)을 이용하여 설계 및 제작되었으며 안테나의 $50{\Omega}$ 급전 선로와 방사면이 RFIC 설계에 적합하도록 동일한 평면 위에서 인쇄되었다. 설계된 안테나의 임피던스 대역폭($VSWR{\leq}2$)은 3.0 GHz로부터 11.0 GHz였으며 전형적인 모노폴 안테나의 방사 패턴이 측정되었다. 안테나의 임피던스 대역폭에 해당하는 주파수 이득(gain)은 $1.4{\sim}4.6\;dBi$로 측정되었고 RFIC 설계에 적합한 초광대역 안테나로 동작하고 있음을 확인할 수 있었다.

This paper presents a coplanar waveguide fed L-planar type monopole antenna which covers ultra wideband(UWB) region of 3.1 GHz to 10.6 GHz. The proposed UWB L-planar type monopole antenna is designed and implemented on the organic substrates( ${\varepsilon}_{r}=3.38,\;@10\;GHz$). The radiation elements, feed line, and ground planes of the antenna are printed on the same conductive layer of the substrates. The bandwidth of the proposed antenna is measured in the range of 3.0 GHz to 11.0 GHz. The measured radiation patterns are symmetrical in E-plane and omni-directional in H-plane. Antenna gains ranges from 1.4 dBi to 4.6 dBi. The proposed UWB antenna shows that the structure is adequate for the design of RFIC.
