Summary:In this paper, we present the analysis of a novel monopole antenna with a reflector. The proposed monopole antenna is printed on a TRF-45 substrate, and the reflector, which is positioned near the base of the antenna, is printed on the FR-4 substrate. Positioning the reflector near the base of the antenna was found to suppress current radiation toward the back of the monopole antenna. Comparative analysis of the proposed monopole antenna and a conventional monopole antenna without a reflector revealed that the bandwidths of the antenna with and without a reflector were 2.65 GHz and 2.88 GHz, respectively. Additionally, the antenna without a reflector was observed to have a bi-directional radiation pattern in the E-plane, and an omni-directional radiation pattern in the H-plane. However, only the antenna with a reflector was found to suppress back radiation, and provide non-uniform directional radiation in the E-plane and H-plane. 본 논문에서는 반사판을 갖는 새로운 모노폴 안테나를 제안 하였다. 제안한 안테나는 TRF-45 기판으로 제작하였으며, 제작한 안테나와 결합한 반사판도 FR-4 기판으로 제작하였다. 안테나 후면에 위치한 반사판으로 인해 후면에 반사되는 전류가 억제되는 것을 확인하였다. 제안한 모노폴 안테나의 대역폭은 2.65 GHz이며, 반사판이 없는 모노폴 안테나의 대역폭은 2.88 GHz이다. 또한, 반사판이 없는 안테나는 E-평면에서 양방향 방사 패턴이 관찰되었으며, H-평면에서는 무지향성의 방사패턴이 관찰되었다. 그러나 반사판을 갖는 안테나의 경우 후방 방사를 억제하며, E-평면과 H-평면에서 지향성 방사를 제공한다.
