Abstract

In this paper, a low-profile and broadband bowtie antenna using multi-layer substrate for UWB sensor application is presented. A compact bowtie antenna is designed and implemented on two multi-layered substrate with total thickness of 4.5 mm. The antenna consists of bowtie radiator and planar-type balun. The designed radiator and balun are connected to each other so that it can be easily implemented in various structures. The implemented antenna provides 3 to 6 dBi of gain for whole frequency range from 6.8 to 10 GHz.

본 논문에서는 UWB 센서에 응용 가능한 다층기판을 이용한 광대역 특성을 가지는 보우타이 안테나를 설계하였다. 제안된 소형 보우타이 안테나는 2층의 기판으로 설계 및 제작되었으며 전체 안테나의 두께는 4.5mm이다. 제안된 안테나는 보우타이 모양의 방사체와 평면형 발룬으로 구성된다. 설계된 방사체와 발룬의 간단한 연결로 안테나가 설계되도록 하여 다양한 구조로 쉽게 구현 가능하도록 하였다. 제작된 안테나는 6.8~10 GHz의 주파수 범위에서 3~6dBi의 이득을 가졌다.
