Abstract

In this paper, a compact antenna is designed for the UWB lower half-band WVAN Gbps data-rate transceiver. The proposed antenna broadens the bandwidth less than -10 dB by placing the ring stubs and an open stub on the rectangular monopole above the partial ground and creating multiple resonant current paths. The designed antenna goes through the electromagnetic simulation and is fabricated and the implemented antenna has the characteristics of the return loss lower than -10 dB, the antenna gain greater than 5 dBi, and the efficiency over 80 % in the UWB lower half-band ranging from 3.197 GHz to 4.732 GHz. Therefore, it is thought that the proposed antenna is suitable for the size-reduced and excellently performing wireless communication transceiver.

본 논문에서는 UWB 하반 대역의 WVAN Gbps 데이터 전송률 트랜시버용 소형 안테나를 설계하였다. 제안된 안테나는 광대역 특성을 얻기 위하여 부분 접지면 상에서 사각형 모노폴에 링형 스터브와 개방 스터브를 부착하여 다수의 공진 전류 경로를 가짐으로써 -10 dB 이하 반사 손실 영역을 넓혔다. 설계된 안테나는 전자기모의시험을 거쳐 제작되었고, UWB 하반 대역인 3.197~4.732 GHz에서 -10 dB 이하의 반사 손실과 5 dBi 이상의 안테나 이득과 80 % 이상의 효율 특성을 보였다. 따라서 제작된 안테나는 소형화는 물론 우수한 성능의 무선 통신 트랜시버용으로 적합한 것으로 판단된다.
